The next frontier of Massive Galaxies and Quasars at the Cosmic Dawn

About this event

Abstract:  I will discuss recent progress in cosmological hydrodynamic simulations of galaxy formation at unprecedented volumes and resolution. I will focus on predictions for the first quasars and their host galaxies and their contribution to reionization from the BlueTides simulation. BlueTides is a uniquely large volume and high resolution simulation of the high redshift universe: with 0.7 trillion particles in a volume half a gigaparsec on a side. This is the first simulation large enough to resolve the relevant scales relevant to the formation of the first large galaxies and quasars. These massive objects at high redshifts will be investigated with the next generation telescopes (Euclid, JWST and WFIRST).

Bio:  TIZIANA DI MATTEO is a Professor in the McWilliams Center for Cosmology of the Physics Department at Carnegie Mellon University. She received her PhD in 1998 at Cambridge University, UK and prior to coming to Carnegie Mellon she was a Chandra Fellow at Harvard and a junior faculty member at the Max Planck Institute for Astrophysics in Germany. Di Matteo is a theorist with expertise in both high energy astrophysics and cosmology. Her interests focus on state-of-the-art cosmological simulations of galaxy formation with special emphasis on modeling the impact of black holes on structure formation in the Universe. Her research makes extensive use of high-performance computing. Di Matteo became a Fellow of the American Physical Society in 2014, she is the recipient of a  Pittsburgh Foundation fellowship, and 2008 Award for Excellence from the Carnegie Science Center. Among other national committees, she has served on the Blue Waters Science and Engineering Team Advisory Committee, NSD XSEDE Allocation Committee, NASA Chandra User Committee and she is a member of the LSST Dark Energy Science Collaboration.
