Italian Society of General Relativity and Gravitation (SIGRAV)

We are pleased to announce the international SIGRAV PhD school 2022, organised by the Italian Society of General Relativity and Gravitation (SIGRAV).

This year our PhD school aims at providing robust and deep knowledge of Cosmology in the context of General Relativity and its possible modifications, with particular attention to phenomenological consequences and observations. The School is based on four courses and two lectures focused on specific topics:

– Early Universe, Inflation and Primordial Gravitational Waves: Mairi Sakellariadou (King’s College)

– Observational perspectives for the Cosmic Microwave Background: Paolo de Bernardis (Sapienza Univ. di Roma)

– Neutrino Cosmology and Dark Matter: Massimiliano Lattanzi (INFN)

– Modified gravity cosmology: Emmanuel Saridakis (National Observatory of Athens)

– Machine learning in cosmology (focused talk): Nicoletta Krachmalnicoff (SISSA)

– Cosmic Microwave Background phenomenology (focused talk), Erminia Calabrese (University of Cardiff)

This is the thirty-fifth Workshop in Particle Physics being held yearly at the Planibel Hotel of La Thuile, Aosta Valley. La Thuile is a beautiful mountain village located 1450 m a.sl., about 40 km north of the city of Aosta, on the road to the Mont Blanc. The hotel is at the bottom of a vast skiing area connected with the French ski resort La Rosiere and it is an outstanding complex for winter sports and congresses. The Rencontres will bring together about 120 active experimentalists and theorists, as well as a number of young students supported by the Organizers, to review the status and the future prospects in elementary particle physics.

The topic of this workshop is the discussion of the “Latest Advances in X-ray Spectroscopy and Polarimetry” related to the upcoming launch of X-ray observatories, such as XRISM, IXPE and Athena, and future proposed missions, such as Lynx and eXTP. These new X-ray missions will enable us to achieve fundamental scientific progresses and discoveries in a wide variety of physical and astrophysical topics, from Galactic black holes and neutron stars to quasars and galaxy clusters, from plasma physics to tests of general relativity, from stellar to galaxy evolution, just to name a few.

Planck‘s recent measurements of the temperature and polarization anisotropies of the Cosmic Microwave Background (CMB) have established a cosmological framework that will remain the standard for many years to come. From space, the LiteBIRD mission will pick up on this legacy in the next decade, with the aim to improve dramatically on polarization observations at large angular scales. In a later time frame, ESA’s recently issued future scientific programme – Voyage 2050 – has highlighted the need for a large space mission to focus on high-precision spectroscopy of the CMB. And both ground-based and balloon-borne observatories are also expected in the coming years to improve significantly on Planck’s observations of the polarized anisotropies of the CMB, especially on smaller angular scales. In order to meet their ambitious objectives, all of these upcoming experiments will have to address and overcome very significant technical and data analysis challenges, some of which have already been revealed by Planck. It is therefore appropriate at this time to examine these challenges from the perspective of the experience accumulated by Planck in the design and operation of its instruments and in the preparation, conduct, and analysis of its all-sky surveys. In this context, the workshop is designed to bring together key members of the Planck and future experiment teams to foster discussion on some of the most challenging topics.

In the view of the forthcoming Big Data era for the astronomy community, the conference focuses on challenges coming from the application of ML/DL methods to open problems in astrophysics: novel AI techniques will be presented and joint discussions on their use with observational data will be fostered.

The Torino Workshops series started in Torino in 1995. Since then, 12 workshops have been held by various institutions around the world. Traditionally, the Torino Workshop focuses on the physics of asymptotic giant branch (AGB) stars and many related topics: stellar evolution and nucleosynthesis, observations (photometry, spectrometry, and asteroseismology), stellar winds, dust and presolar grain formation, galactic chemical evolution, theoretical and experimental nuclear astrophysics. The workshop will bring together experts, and friends, involved in these research fields to identify current key scientific questions and the possible ways to address them by interdisciplinary approaches. This meeting edition will celebrate Prof. Maurizio M. Busso on the occasion of his 70th birthday. Maurizio is among the founders of the Torino Workshop and during his career he has given important contributions to the study of AGB stars and related fields covered in the workshop.

The Nuclear Spectroscopic Telescope Array (NuSTAR) is the first focusing hard X-ray (>10 keV) satellite in orbit, and is providing unprecedented data on energetic phenomena ranging from the solar system to distant quasars. Since 2015, the observatory has primarily been run as a guest observer facility, with programs competitively selected by time allocation committees. A significant fraction of NuSTAR observatory time is coordinated with other high-energy observatories. This conference will be an opportunity to explore the range of science that NuSTAR is conducting, with sessions focused on topics including Galactic binaries, extreme transients, ultraluminous X-ray sources (ULXs), the census of obscured AGN in the local universe, black hole physics, and future high-energy facilities. Talks and posters on additional topics are also expected and encouraged.

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.

This conference will bring together experts in the study of the CGM and galaxy environment both from an observational and a theoretical point of view. Through close interactions across these fields, we aim to understand how the major physical processes occurring inside galaxies, in the CGM, and within the large-scale environment intertwine to regulate the formation of cosmic structures across time.
