SUMMARY:IllustrisTNG and insights about the evolution of galaxies in differ
 ent environments
DESCRIPTION:IllustrisTNG and insights about the evolution of galaxies in di
 fferent environments\nDr. Annalisa Pillepich\n\nI will describe the numeri
 cal efforts to simulate galaxies with the  moving-mesh code AREPO across a
 n unprecedented range of halo masses,  environments, evolutionary stages a
 nd cosmic times. In particular, I  will focus on the IllustrisTNG project 
 (www.tng-project.org <http://www.tng-project.org>),  a series of thr
 ee gravity+magnetohydrodynamics cosmological volumes of  50, 100, and 300 
 Mpc a side, respectively, in a LCDM cosmology. With  these, we are capable
  of both resolving the inner structures of galaxies  as small as the class
 ical dwarfs of the Milky Way, as well as of  sampling the large scale stru
 cture of the Universe with thousands among  massive groups and clusters of
  galaxies. I will discuss what is  explicitly and empirically solved in gr
 avity+magnetohydrodynamics  simulations for galaxy formation in a cosmolog
 ical context and what is  required and what it means to “successfull
 y” reproduce populations of  galaxies which resemble the real ones. 
 I will therefore show novel  insights allowed by the new simulations, rang
 ing from the assembly of  the most massive structures in the Universe, to 
 the effects of baryons  of the phase-space properties of dark matter and t
 o the changes in the  star-formation activity and morphological mix of gal
 axies at early  epochs.
