Abstract

天文学談話会 兼GPPUセミナー

I report the results of large cosmological N-body simulations of small and large scale structure formation in the Universe. In the first topic, I will show the density structures of subhalos of dwarf spheroidal galaxies and discuss how we can constrain the nature of dark matter by comparing with observations. In the second topic, I will introduce the Uchuu suite of large high-resolution cosmological N-body simulations. The largest simulation, named Uchuu, consists of 2.1 trillion dark matter particles in a box of 2.0 Gpc/h. We can follow the evolution of dark matter halos (and subhalos) spanning from dwarf galaxies to massive galaxy cluster hosts. We make publicly available various N-body products, as part of Data Release 1. I will also present a roadmap for Data Release 2, in which galaxies and AGN mock catalogs constructed by various models are provided.
