Meetings/Workshops on Astronomy, Astrophysics and Cosmology in Japan

Kavli IPMU, The University of Tokyo

Going into the 2020s, cosmic large scale structure will be mapped with increasing detail by the next generation of observational facilities operating at various wavelengths (radio, optical, infra-red) and exploiting various techniques. Meanwhile, theory and simulations are increasing in sophistication in their ability to describe large-scale structure. These advances could potentially allow greater constraints into cosmological parameters and theories of galaxy evolution.

The goal of this meeting at the Kavli Institute for the Physics and Mathematics of the Universe (IPMU) is to prepare for new and upcoming spectroscopic surveys such as DESI, Subaru PFS and MOONS, which will probe the cosmic web and large-scale structure at unprecedented target densities and redshifts, and to bring together a diverse group of researchers working on the cosmic web, its various tracers, and their embedded galaxies from both observational and theoretical perspectives. This will be an opportunity for researchers who may not usually encounter each other to interact.

Characterizing and modeling the cosmic web, Observational surveys of the cosmic web, ongoing and planned, The growth of protoclusters into clusters, Statistical measurements beyond 2-point, Galaxy evolution in the context of the cosmic web, Constrained realization modeling of large-scale structure, The intergalactic medium tracing the cosmic web, Exploiting cosmic voids for cosmology

The Local Group offers a unique opportunity to study galaxy formation, the epoch of reionization, chemical evolution, and the nature of dark matter in our cosmic backyard, through detailed observations of resolved stellar populations. Ongoing and upcoming space missions like Gaia, Roman and large spectroscopic/photometric surveys (DESI, SDSS-V, WEAVE, PFS, 4MOST, LSST), which will bring detailed phase-space and chemical information for millions/billions of stars, will revolutionize near-field cosmology. The sheer increase in size and depth of these samples will provide valuable information to propose new astrophysical tests on the nature of the dark matter and constrain the formation of galaxies. The goal of this meeting is to bring together experts to discuss all aspects of Galactic Archaeology and dark matter research in the Local Group (galaxy formation, dynamics, chemical evolution, EMPs, first stars) and offering a platform to forge new collaborations among scientists.

Galactic Archaeology in the Milky Way and Andromeda, Chemistry: (EMP and Chemical evolution), Galaxy formation in the Local Group (simulations), Satellites of the Local Group and beyond, Dark matter (substructure & distribution)
