Our Galactic Ecosystem: Opportunities and Diagnostics in the Infrared and Beyond
28 fév 2022 - 04 mar 2022 • UCLA Lake Arrowhead Lodge, Lake Arrowhead, États-Unis
Résumé:
The far infrared contains critical information about galactic ecosystem; The circle of life of stars and planets. How does interstellar material cycle between atomic and molecular clouds, and how does its chemical composition (and particularly the abundance of hydride molecules) reflect the environment in which it is found? What is the role of feedback (from young and old stars) on the interstellar medium (ISM)? What is the role of magnetic fields in the evolution of the ISM and star formation?

SOFIA provides a flexible, and our currently only, general access to the far infrared (30-300 µm) and its tracers of atomic and molecular lines and FIR polarization. This conference will allow in-person discussions of the results and future opportunities in studying galactic ecosystem using FIR methods, from SOFIA and other platforms. A goal will be to explore synergy with other observatories, including JWST and ALMA, and with theory.

Fifty Years of the Skumanich Relations
08 mar 2022 - 11 mar 2022 • Boulder, États-Unis
Résumé:
In February 1972, the Astrophysical Journal published "Time Scales for Ca II Emission Decay, Rotational Braking, and Lithium Depletion" by Dr. Andrew Skumanich, a research scientist at the High Altitude Observatory (HAO) in Boulder, Colorado. The paper is one of the most impactful publications in the history of HAO, with more than 1500 citations to date. To celebrate the 50th anniversary of this publication, we will host an in-person conference on 8‑11 March 2022, organized around the major science themes of the paper: magnetic activity, stellar rotation, and lithium depletion.

Building Bridges: Towards a Unified Picture of Stellar and Black Hole Binary Accretion and Evolution
14 mar 2022 - 17 mar 2022 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
Binary systems are ubiquitous in nature, from stars to the supermassive black holes expected to reside in galactic nuclei. In many circumstances, the binary system is enveloped by circumbinary gas. How does circumbinary gas evolve and influence the embedded binary? What observational signatures of this gas are most informative? What novel numerical techniques must we deploy to better model these systems? This conference will bring together two distinct communities: those working on massive black hole binaries with those working on stellar binaries. Because recent years have seen remarkable progress in observations of stellar binaries, and numerical modeling of both stars and black holes, now is the ideal time to bring together these two groups. The conference will highlight the remarkable similarities of problems at such varied astrophysical scales, and shed light on the crucial next steps for pushing the boundaries of our knowledge.

Storming the Gravitational Wave Frontier
19 avr 2022 - 22 avr 2022 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
The detection of gravitational waves by Advanced LIGO/Virgo has opened a new frontier in physics, with impact on areas ranging from field theory through stellar evolution and cosmology. It has also seeded new connections between theoretical communities, especially between field theorists and classical relativists. An even brighter future lies ahead, with more sensitive ground-based detectors and, eventually, a space-based observatory. Current and future experiments demand precision modelling of gravitational-wave signals in order to interpret the strongest gravitational-wave events and to enable sensitive searches for new physics which may be embedded in these signals. The conference will bring together experts from three communities: classical relativity, effective field theory, and scattering amplitudes. Building on the current state of the art, we will discuss the needs of the next generation of gravitational-wave experiments; identify which challenges theory must overcome; highlight recent advances in gravitational wave modelling for more detailed study; and uncover the most promising emerging tools and techniques from classical and quantum field theory for further development.

Computational Astrophysics in the ngVLA Era: Synergistic Simulations, Theory, and Observations
07 jui 2022 - 09 jui 2022 • Flatiron Institute, New York, NY, États-Unis
Résumé:
The goal of this meeting is to bring together theoreticians, modelers, and observers to discuss the computational astrophysics and observational challenges for the next generation of observatories, focusing on the next generation Very Large Array (ngVLA). The formation of planetary systems, the evolution of galaxies, and the observation of electromagnetic counterparts of gravitational wave events will be fertile grounds for discovery in the next decades and are core science goals for the ngVLA. The challenge to simulators is to develop predictive models that can be accurately compared against observations, while observers need to generate measurements that can effectively constrain the models.

SETI Symposium — The First Penn State Extraterrestrial Intelligence Symposium
27 jui 2022 - 30 jui 2022 • University Park, États-Unis
Organisateur:
Presented by the Penn State Extraterrestrial Intelligence Center
Résumé:
The symposium will take an ecumenical view of SETI as the astronomical search for technosignatures, and as a subfield of astrobiology. It will encompass technosignatures across and beyond the electromagnetic spectrum, including (but not limited to) radio, microwave, optical, and NIR signals compressed in the time and frequency domains; multimessenger astronomy; megastructures in transit and thermal emission; and solar system SETI.

The symposium will lean heavily towards astronomical, observational programs that can detect or put quantitative upper limits on technosignatures, and theoretical work in direct support of such programs such as calculations of relative and absolute figures of merit of past and current programs, or target selection and observation strategy work. Abstracts on putting current efforts in a historical context, interfaces with the social sciences, the funding and cultural landscape of SETI, and curricular and academic dimensions of the field are also welcome.

2022 Sagan Summer Workshop — Exoplanet Science in the Gaia Era
25 jul 2022 - 29 jul 2022 • California Institute of Technology, Pasadena, CA - hybrid, États-Unis
Organisateur:
Hosted by The NASA Exoplanet Science Institute, California Institute of Technology, Pasadena, CA
Résumé:
The 2022 Sagan Summer Workshop will focus on the topic of exoplanet science in the Gaia era. The ESA Gaia mission has been mapping the Galaxy for over seven years, measuring very accurate positions and motions of over 1 billion stars. It has already greatly contributed to exoplanet science through the determination of more accurate stellar parameters, which in turn improve planet parameters, the detection of stellar companions, and the identification and characterization of young moving groups. In the near future, the unprecedented astrometric accuracy will result in the discovery of new exoplanets, as well as the characterization of known planets. The workshop will introduce the basics of astrometry, the impact of Gaia astrometry on astrophysics, and the astrometric detection and characterization of exoplanets. The synergy between the different planet detection techniques of astrometry, transits, radial velocities, and imaging will be discussed, as well as future advances in astrometry.

The Sagan Summer Workshops are aimed at advanced undergraduates, grad students, and postdocs, however all are welcome to attend. There is no registration fee for these workshops and the registration link will be available in February 2022.

White Dwarfs as Probes of the Evolution of Planets, Stars, the Milky Way and the Expanding Universe
17 oct 2022 - 16 dec 2022 • Santa Barbara, California, États-Unis
Résumé:
This program is motivated by the recent observational insights concerning white dwarfs as individuals and as a population, based on the astrometry from Gaia and large photometric (Kepler, TESS, ZTF, VeraRubin) and spectroscopic (SDSS-V, DESI, WEAVE, 4MOST) surveys. Some of the questions that these data, combined with improved input physics and white dwarf models, will answer are: How does crystallization affect white dwarf cooling? How good is our understanding of convection, overshoot, and mixing in general? How good are the predictions of the low-frequency gravitational wave foreground and thermonuclear supernovae rates (SN Ia, Iax, Ca transients)? What is the nature of the recently discovered stellar remnants of thermonuclear supernova and/or their donors? What are the architectures of planetary systems that survive the metamorphosis of their host stars into white dwarfs, and what is their ultimate fate?

White Dwarfs from Physics to Astrophysics
14 nov 2022 - 17 nov 2022 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
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.

Gravity from algebra: modern field theory methods for holography
23 jan 2023 - 26 jan 2023 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
The last several years have seen rapid development of a new language for conformal field theory(CFT), including insights from the conformal bootstrap program. This conference will bring to bear the modern arsenal of conformal field theory on the foundations of holography and quantum gravity. A theme of the conference will be the extent to which consistency conditions on quantum gravity are inherited from those of CFT, and whether they naturally lead to string/M-theory. By bringing together scientists on both sides of holographic duality, we hope to explore these issues in a broad way.Topics to be covered include large N bootstrap and the structure of holographic CFTs dual to general relativity; CFT sum rules and gravitational effective field theory; aspects of supersymmetry in holography; low-dimensional holography, modularity and quantum chaos; black holes from strongly-coupled finite temperature physics; symmetry constraints on gravitational path integrals and AdS vacua; S-matrices, their relation to CFT correlators, and holography away from AdS.

The Co-evolution of the Cosmic Web and Galaxies across Cosmic Time
06 fév 2023 - 09 fév 2023 • Santa Barbara, États-Unis
Organisateur:
UC Santa Barbara, Kavli Institute for Theoretical Physics (KITP)
Résumé:
The cosmic web of the matter distribution in the universe provides the framework for the formation and evolution of galaxies and is fundamental to connect galactic properties to cosmology. This conference will address the effects of the cosmic web upon galaxies and vice versa. The aim is to create both a broad-brush and then, for some aspects, a more detailed, early to late time joint history of the web and galaxies. Indeed, the web reflects what the universe is on intermediate scales, which are informative, both in terms of cosmic evolution and quantity of data. It acts as a dynamically relevant intermediate-density bridge (easier to model) between cosmology and galaxies. It is also the source of all anisotropy, critical for angular momentum acquisition, which is the number two parameter in galaxy formation.
