SUMMARY:The Astrophysics of Gas with Simulations \, Astronomy Colloqui
um\, Simeon Bird\, UC Riverside
DESCRIPTION:The large scale distribution of gas in the Universe contai
ns
\nthe answers to many mysteries\, such as the nature of dark matter
\, the sources of ionizing photons\, and global trends in star formati
on. Cosmological simulations are the only way to understand these ques
tions. I will talk about our ongoing simulation effort\, ASTERIX. A pa
rticular focus of ASTERIX is z > 2\, the era probed by upcoming NASA f
lagship missions JWST and WFIRST. In pursuit of this focus\, we have i
mplemented novel models for hydrogen and helium reionization\, and run
a 250 Mpc/hbox simulation with a resolution comparable to Illustris-T
NG 100. I will discuss our models and present some preliminary results
at z > 5.
