galaxy formation and evolution, stellar core collapses, supernova explosions

In the last few years there has been renewed interest in QCD and hadronic dynamics using holographic gauge/gravity duality, resurge of the large N methods, progress in string models, integrability, unitarity and bootstrap and more. Also, many new experimental results were reported by ALICE at LHC regarding collectivization in pp and pA collisions, by LHCb at CERN and the B- and C-factories regarding the existence of exotics and the spectroscopy of heavy-light systems, and more recently the reporting of 2 neutron star mergers by the LIGO collaboration and its constraint on the nuclear dense equation of state. The conference will bring together practitioners of these interdisciplinary fields to discuss these exciting new developments, and explore the relevance of the holographic framework for addressing these observations.

The International Cosmic Ray Conference, or ICRC, is a physics conference organized biennially by the Commission C4 (Astroparticle Physics) of the International Union of Pure and Applied Sciences (IUPAP) since 1947, where physicists from the world present the results of their research in Astroparticle Physics. The meeting covers cosmic-ray physics, neutrino physics, gamma-ray astonomy, dark matter, particle astrophysics, and detector techniques in these fields.

The Kurt Gödel Society intends to celebrate the 70th anniversary of Gödel’s seminal publication and the 100th anniversary of the decisive experimental verification of general relativity by organizing a conference at the University of Vienna, Austria. This event should bring together the prominent researchers from the fields of Physics, Mathematics, Philosophy and Artificial Intelligence.

The nature of the progenitors of Type Ia supernovae (SNe Ia) has remained unclear though SNe Ia play a vital role in many areas of modern astrophysics. Numerous progenitor models have been proposed in the past, including the single-degenerate (SD) model, the double-degenerate (DD) model, the sub-Chandrasekhar mass model, and quite a few variants of these. The progenitor debate has remained heated in recent years as new observations, new explosion simulations and new supernova models have provided a wealth of new, sometimes contradictory constraints; different population synthesis models also make different predictions, although - with standard assumptions - they generally do not produce the required rates in either the Chandrasekhar-mass SD or DD model. On the other hand, there has been doubt whether sub-Chandrasekhar models can reproduce the observed properties of the majority of SN Ia explosions. Different observational constraints seem to favour different progenitor models. This conference is held to deepen our understanding of the progenitors of SNe Ia, to elucidate the connection between the progenitors and the observed properties of SNe Ia and their remnants and to provide a pathway of how to ultimately resolve the debate.

One of the most important and long-lasting challenges of modern astrophysics is understanding and unveiling the nature of dark matter. Despite the many uncertainties on its composition, dark matter is considered the main driver of large-scale structure formation in the Universe and, together with dark energy, accounts for 95 per cent of the total energy budget of the universe. The nature of dark matter and the standard LCDM models can be tested on many scales, from the shape of the cosmic web to the properties of galaxies and galaxy clusters, down to particle physics experiments aiming at detecting the dark matter particles. This conference aims at bringing together experts on galaxies, galaxy clusters, numerical simulations and observations, as well as dark matter detectors and alternative cosmological models. In this way, we hope to encourage stimulating and comprehensive discussions on the state of the art of dark matter models and boost research collaboration between different sides.

The purpose of the meeting is to bring together experts and young researchers in the areas of nuclear, particle and astro-physics as well as cosmology and the pertinent interrelations among these fields. The aim is to discuss the current status of the field and to explore future directions, both in experiment and theory. With the recent observation of gravitational-wave signals of black-hole and neutron-star mergers - for the latter in coincidence with electromagnetic signals -, the meeting is particularly timely. The aim is to cover a broad range of topics to elucidate synergies and identify areas of future progress. This should be especially beneficial to the younger participants of the meeting.

The rich taxonomy of galaxies we observe today is understood to be regulated by two competing processes: accretion and feedback. Understanding the intricate exchange of regular matter between star-forming regions and the intergalactic space and its impact on subsequent galaxy growth remains a primary goal in astrophysics research. This meeting will bring together leading theorists and observers to discuss the latest progress in studying baryonic flows in and out of galaxies with an outlook towards key growth areas in the era of giant telescopes.

Gravitational waves promise a new window into the highest-energy events in the evolution of the universe. The recent LIGO/Virgo detections of gravitational waves from the mergers of binary black holes and binary neutron stars and have ignited interest in the future direction of gravitational wave astronomy. A space-based laser interferometer, pioneered by NASA's LISA concept and the European Space Agency's eLISA program and ESA's recent spectacularly successful LISA Pathfinder mission, would enable direct detection of gravitational waves in the milliHertz range. A lower frequency range would allow detection of supermassive black hole mergers, tracing the galaxy merger history and serving as cosmic sirens to probe the universe's expansion history, as well as precursors for the LIGO sources. A space-based detector would also be sensitive to stochastic gravitational wave backgrounds produced by unknown physics operating in the very early universe, including an electroweak phase transition. This Nordita program will bring scientists together to engage in an effort to characterize and detect sources contributing to the gravitational wave background from the early universe, and the implications for new physics at the TeV scale and beyond.

One of the greatest current unsolved problems in physics is whether gravity, which is the least understood of the fundamental "forces", is universally Newtonian in the classical limit. The nature of gravitation is even unclear, but whatever the physical origin of gravitation, the empirical formulation of how a body is accelerated as a result of the mass-distribution around it can be applied to study the formation and evolution of galaxies.

With this meeting we aim to foster a discussion between the scientists who have been studying galaxies and cosmology in the dark matter and Milgromian frameworks which constitute two fundamentally different hypotheses. The aim is to achieve an exchange notably also on the technical challenges in applying both hypothesis to computational astrophysics problems in view of recent advances in understanding stellar populations, which are important for quantifying feedback processes.

NuSTAR (Nuclear Spectroscopic Telescope Array)

Ten years after the celebration of the First Workshop on robotic autonomous observatories in Málaga, the number of automatic astronomical facilities worldwide has significantly grown, as well as the level of robotisation, autonomy, and networking, with many recent developments motivated by the search of new electromagnetic counterparts to gravitational waves in the next months. This has a strong impact in many other astrophysical fields, like fireballs detection, minor planet studies, the search for extra-solar planets, the monitoring of variable stars in our Galaxy, the study of active galactic nuclei, the detection and monitoring of supernovae, and the immediate follow-up of high-energy transients such as cosmic gamma-ray bursts, besides the search of neutrino and gravitational waves electromagnetic counterparts. Last, but not least, space debris surveillance and tracking is another field of increasing interest. Educational aspects will be also covered.

Thus, the main focus of the workshop will be on the new and existing astronomical facilities whose goal is to observe a wide variety of astrophysical targets with no (or very little) human interaction. As in the past 10 years, we expect the workshop will continue as an international forum for researchers to summarize the most recent developments and ideas in the field, with a special emphasis given to the Technical and Scientific results obtained within the last two years and future developments, with specific sessions on Educational Activities and Space Surveillance and Tracking.

Following the tradition of the previous NuSYM symposia, NuSYM2019 is aimed to host synergies between the studies of nuclear structure, of nuclear reactions and of astrophysics, including new exciting ideas and all possible breakthroughs. The nuclear symmetry energy and its density dependence are known to govern to a large extent the physics of nuclear masses and radii, the collective excitations at moderate excitation energies, up to the dynamics and observables of the high-energy heavy-ion collisions that explore regimes characterized by higher densities and isospin asymmetry of nuclear matter, especially, with radioactive beams. Last but not least, the understanding of the density dependence of nuclear symmetry energy is of paramount importance in the context of the forefront research related to the astrophysical modelling of the stellar and explosive nucleosynthesis, of supernovae and kilonovae (first observed in the aftermath of GW170817), as well as of the properties of neutron stars and their mergers.

The goal of this meeting is to bring together a focused group of experts (~40, see below) who are actively working on the circumgalactic medium, from both the theoretical and observational perspectives.

One of the challenges of the LSST community is to optimize the scientific return of observations by preparing participants to source separation (i.e. de-blending) for different science cases. The purpose of the workshop is to study in detail the application of the Scarlet pipeline for de-blending sources in different astrophysical contexts of interest for the LSST community.

NuSTAR (Nuclear Spectroscopic Telescope Array)

The two Fermi instruments have been surveying the high-energy sky since August 2008. The Large Area Telescope (LAT) has discovered more than a thousand new sources and many new source classes, bringing the importance of gamma-ray astrophysics to an ever-broadening community.

The interplay between ubiquitous dust, ice and gas in space knits an interesting tale from collapsing interstellar clouds to the formation of new stars, planets, moons and comets. Along this path, the formation of complex organic molecules necessary to construct the building blocks of life brings us a step closer to the understanding of the evolution of life. The advancement in the understanding of these vast intricacies of space lies in the development of varied laboratory techniques and astrophysical modelling in close connection with space exploration and astronomical observations. We are living a very exciting time at the interplay between current and future missions/facilities. Return of extra-terrestrial samples is one of the drivers of these missions (e.g. Hayabusa 2, OSIRIS-Rex) together with a more and more detailed exploration of the Solar System planets, moons and other bodies (e.g. Martian rovers ExoMars and Mars 2020, BepiColumbo for Mercury, the future JUICE and Europa Clipper missions for Jupiter and its moon Europa). From the astronomical side, new perspectives arise from progress in high angular resolution observations from the optical/infrared (VLT and the coming JWST and ELT) to the sub-mm/mm range (ALMA, NOEMA) to the mid-radio frequencies (SKA) together with a better coverage of the electromagnetic spectrum (e.g. ATHENA for X-rays) and the discovery of new exo-worlds (e.g. PLATO, ARIEL). The ECLA 2020 conference will provide the opportunity for interdisciplinary exchanges between scientists active in different research fields, which range from astronomy to geology and from chemistry to instrumentation. These interactions will foster collaborations that will result in better scientific exploitation of missions/facilities in planetology and astronomy in relation with the major questions on our origins.

As general structure for the programme, we aim at discussing probes of cosmic expansion, tests of structure growth and at understanding the implications of combining them. Different competing theoretical scenarios, both of the “modified matter” and “modified gravity” kinds, will be compared against each another. Both the theoretical and experimental/observational viewpoints will be represented and discussed.

This conference will synthesize recent observational discoveries of massive star clusters in nearby galaxies and the high-redshift universe. It will connect the observations to theoretical modeling of galaxy formation on large scales and star formation on small scales. The topics for discussion will include the efficiency of star cluster formation as a function of environment, and the origins of the cluster age and metallicity distributions. The meeting will aim to highlight the similarities and differences in star formation in low-redshift and high-redshift galaxies.

This programme will bring together experts with complementary expertise in observation, theory, solar system and extrasolar planets to assess the current status of planet formation models, highlight problems in each formation stage, and explore the possibility of developing comprehensive models that can be applied to different planetary systems.

The LSST project is moving forward in the construction phase, and activities in the LSST Science Collaborations (Solar System; Stars, the Milky Way and Local Volume; Transients and Variable Stars; Galaxies; AGN; Strong Lensing; Dark Energy and Informatics and Statistics) are vibrant and involve a significant European participation.

Kavli Institute for Theoretical Physics (KITP)

The circumgalactic medium (CGM) can be viewed as an atmosphere that surrounds a galaxy and sustains star formation within it. Much of what we know about the CGM has come from absorption-line spectroscopy, mainly in the UV band, of gas at temperatures below the galaxy's virial temperature. A comparable amount of hotter gas, closer to the virial temperature, may also be present but has been harder to detect. If it is there, then the properties of the cooler clouds and the hotter ambient medium are likely to be complementary, deeply interwoven, and physically complex. It follows that the physics of cosmic rays, magnetic fields, turbulent mixing layers, conductive interfaces, and shocks may then play a leading role in setting the fate of the multiphase CGM. This conference will examine the evidence for a virial-temperature component along with the observations capable of revealing its properties and its relationship to the cooler components. Probes that complement UV absorption-line observations will be emphasized, including X-ray emission and absorption, UV and optical emission, Sunyaev-Zel'dovich probes, Fast Radio Bursts, and signposts of non-thermal particle acceleration.

Kavli Institute for Theoretical Physics (KITP)

Astrometric, photometric and spectroscopic all-sky surveys provide the first complete, unbiased view of the Galactic population of the most abundant type of stellar remnants: white dwarfs. This wealth of observational data provides an array of opportunities to use white dwarfs as probes of a wide range of astrophysics, including the formation and evolution of stars and planets, the star formation rate of the Galaxy, and the populations of low-frequency gravitational wave sources and progenitors of thermonuclear supernovae. These applications require improved models of these electron-degenerate stars, which in turn rely on developments in the relevant input physics, including equations of state and opacities. This conference will provide a joint platform for experts in the observational and theoretical study of white dwarfs, scientists working on the underlying fundamental physics, and astronomers using white dwarfs as diagnostic tools to gain a panoramic overview of the state-of-the-art, to identify remaining limitations of the current models, and to explore novel scientific opportunities arising from the new data.
