This is a talk given at lunch time, usually in the conference room at noon.
It was once accepted that galaxies form thin disks early: collisional gas with high velocity dispersion should dissipate energy, conserve angular momentum, and develop strong disk-like rotational support in only a few galaxy crossing times (~few hundred Myr).
Surveys reach sub-Milky Way masses at z>2 and numerical models produce realistic
The origin of Type Ia Supernovae (SNe) is not well understood.
Understanding the gaseous halo surrounding a galaxy is an integral part to understanding galaxy evolution.
Novel methods in recent years have been developed for numerically solving the hydrodynamical and MHD equations relevant to all kinds of astrophysical flows. I will first
The detection of an electromagnetic counterpart associated with a gravitational wave detection by the Advanced LIGO and VIRGO interferometers is one of the great observational challenges of our time.
Less than 1 billion year after the Big Bang (< 8% of today’s age of the Universe), the cosmic star formation rate and stellar mass density of gala
