In the last decade, increasingly strong efforts have been devoted to understand the role of active galactic nuclei (AGN) during the cosmic evolution of galaxies, groups and clusters of galaxies. Chandra, XMM-Newton, and Hitomi have unveiled spectacular interactions of the central supermassive black hole (SMBH) with the host atmosphere in the form of resolved X-ray cavities, shocks, metal uplifts, and turbulence. At the same time, the hot halos of galaxies, groups, and clusters recurrently condense in localized regions forming multiphase filaments and clouds that rain onto the central SMBH and that are detected via optical/IR/radio telescopes (e.g., HST, Magellan, VLT, IRAM, SOFIA). In the nuclear region, spectroscopical studies of AGN have discovered an amazing diversity of feeding and feedback phenomena, including ultrafast outflows, warm absorbers, massive ionized, neutral and molecular outflows. With the advent of next-generation telescopes (e.g., ALMA, MUSE, JWST, XARM, Athena, LOFAR/SKA), we are starting to learn that multiphase outflows are an ubiquitous phenomenon in cosmic structures of different masses and ages. Linking the macro to micro scales — and vice versa — of feeding and feedback processes is thus vital to advance our knowledge on the (co)evolution of black holes, galaxies, and clusters of galaxies. The aim of the workshop is to bring together active researchers in the above tightly related — but often disjointed — fields in order to discuss the latest results, confront state-of-the-art simulations/models and observations, as well as promote new collaborations and set the path to future observational and numerical campaigns.

Cosmology offers today one of the most important frontiers of physics. The mystery of dark matter and the puzzle of dark energy are still outstanding. On the observational side, there is an exponential growth of accurate and important data, which will help in establishing the new needed theories. In this conference we plan to bring together researchers from the observational, computer simulation and theoretical sides working in cosmology, astrophysics and astroparticle physics, to discuss the current situation as well as prospects for the future improvements.

The topics to be discussed will include: DM (Theory, Observations, Detection) , The present Cosmological Model , Structures in the Universe , New observational probes of the Universe , Multimessenger cosmology (Gravitational waves, Cosmic rays, Neutrinos)

The workshop will gather together a group of experts on surveys, follow-up observations, stellar evolutionary theory, stellar physics, and population synthesis aimed at confronting the observational properties of each subclass with theory.

NOW 2020 is the 11th workshop of a series started in 1998 in Amsterdam and held since 2000 in the Apulian region of Italy. The aim of the workshop is: to discuss Neutrino Oscillation Physics, in particular current experimental data and their theoretical interpretation; to outline future investigations of neutrino masses and mixings; and to explore the links with various research fields in Astroparticle Physics and Cosmology.

The discovery of multiple stellar populations in globular clusters (GCs) represents one of the most important results of the research in the field of stellar astrophysics. The last two decades witnessed a growing number of studies which, by reversing our vision of simple stellar systems compatible with an isochrone, unveiled the complex nature of the GCs . High-precision photometry color-magnitude diagrams revealed that GCs are composed of two or more discrete stellar groups with specific chemical compositions: one with abundances typical of halo field stars, the other(s) with enhanced light-elements as nitrogen and sodium. A sub-group of clusters also exhibits variations in heavy-elements and iron. Several scenarios of formation and evolution of multiple stellar populations have been proposed so far but none of them fulfills at once all the numerous observational constraints. Important questions, therefore, are still open: How did GCs form in the early Universe? What is their role in the assembly of the Galaxy? Did they significantly contribute to the reionization of the Universe? The aim of this conference is to connect observation and theory to review the state-of-the-art on multiple populations in GCs and discuss the developments of GC studies in the next future.

"The 9th Microquasar Workshop: Celebrating over 50 years of discovery" will be held in Cagliari (Sardinia), Italy, on 21-25 September 2020. It is the ninth in a series of conferences mainly devoted to microquasars but also covering relativistic jet sources in a broader context. It will also be an occasion to celebrate the 50 years since the discovery of variable radio emission from X-ray binaries. The workshop aims to present and discuss the latest results related to X-ray binaries, in particular accretion/ejection physics (multi-wavelength observations and theory/simulations), the properties, mechanisms and interplays of the accretion disk, disk winds, jets, accretion/ejection at all scales, and comparison with the various accretions (BH, NS, CV). The formation, evolution and merging of compact objects in binaries will also be addressed. In the context of recent missions devoted to transient sources, new facilities will be discussed (such as NICER, HXMT, MeerKAT, ASKAP, etc), in addition to new tools and diagnostics based on X-ray timing.

This conference will cover all the topics related to the classical nova phenomenology and related systems, and will include a series of lecture-style talks held by experts in the respective fields anticipating the main conference. The reason for this structure consists in providing to all the attending researcher the right tools and background to follow the multi-disciplinary approach to the phenomenology of nova systems.

A conference to gather an overview of the status and future prospects of astrophysics and cosmology with a multimessenger approach. The conference will feature only plenary sessions on the following topics: astrophysics with electromagnetic waves, astrophysics with gravitational waves, astroparticle physics and neutrino astrophysics, nuclear astrophysics, cosmology. The conference was originally planned for 2020 and moved to 2021 because of the Covid-19 emergency situation.
