Quantifying and Understanding the Galaxy—Halo Connection

Coordinators: Andrey Kravtsov, Alexie Leauthaud, Risa Wechsler, and Andrew Zentner

Scientific Advisors: Carlos Frenk, Marla Geha, Romain Teyssier, and Martin White

Galaxy clustering statistics are fundamental observables that can be used to inform models of galaxy formation and constrain cosmology. Empirical models of the relationship between galaxies and dark matter halos, in which they form and evolve, have proven to be very useful in interpreting such observed statistics. Their proper interpretation is also critical for using observations to constrain galaxy evolution and cosmology, including the nature of the dark energy and dark matter, the neutrino mass, or possible deviations from general relativity using the next generation of massive, wide-field surveys. However, maximizing the scientific impact of these forthcoming data sets requires bringing phenomenological models of the galaxy-dark matter halo connection to a qualitatively different level of accuracy.

This conference will provide an opportunity for researchers working on numerous aspects of theoretical, numerical and observational galaxy formation and cosmology to interact with the goals of understanding the following issues: (1) how contemporary data inform the galaxy-halo connection and its implications for models of galaxy formation and cosmology; (2) the ideas for more sophisticated models that include effects such as assembly bias; (3) the level of accuracy required for the interpretation of forthcoming data sets; and (4) the most promising avenues for developing empirical galaxy-halo models to interpret observations of galaxies and their spatial statistics. We encourage researchers with broad interests in these goals and questions to attend and contribute.

PLEASE NOTE: During the conference there will be an opportunity to present a poster. If you are interested in presenting a poster please visit the conference website and submit your title and abstract. Each poster board is 4 feet high x 6 feet wide. We ask that the posters be no larger than 44 inches high x 34 inches wide at the most.
