Colloquium
Star and galaxy formation, then and now
Abstract
This lecture will address recent progress in modeling the emergence of cosmic structure at high redshifts. Also new insights gained from numerical simulations into the processes relevant for star formation are presented. Rapid magnetic field growth in galaxies and the important role of proto-stellar outflows regulating star formation up to pc scales are particularly highlighted.

About the speaker
Dr. Abel's research interests are ab initio supercomputer calculations in cosmological and astrophysical systems. He has shown from first principles that the very first luminous objects are very massive stars and has developed novel numerical algorithms using adaptive mesh refinement simulations capturing over 14 orders of magnitude in length and time scales. He currently continues his work on the first stars and first galaxies and their role in chemical enrichment and cosmological reionization. Recently he has also studied relativistic astrophysical flows and magneto-hydrodynamic effects in present day star formation. His research program focuses on building galaxies one star at a time. He heads the KIPAC computational physics department which provides super-computing resources and algorithmic advice to members of KIPAC.
