Speaker: Dr. Xiaohui Fan – Steward Observatory
Topic: Dark Energy Spectroscopic Instrument (DESI)
Dr. Fan is an observational cosmologist. Answering questions such as: When did the first luminous objects appear
in the Universe? How did the first generation galaxies & quasars heat up the intergalactic gas, re-ionize the Universe
and end the cosmic dark ages with facilities such as ALMA and HST. He also is studying spectroscopic properties of the
first generation galaxies, using LBT, HST, and soon with JWST. In addition, he is working on a project called “MAMMOTH”, a novel survey of the most massive large scale structure and protocluster environments at the peak of cosmic star formation.
