Disc gravitational instability has a strong impact on galaxy scaling relation

 

Abstract

It is well known that gravitational instability is one of the engines behind the dynamics of disc galaxies, where it enters a variety of processes.  Brand new work is demonstrating that disc gravitational instability has even a strong impact on galaxy scaling relations.  In this talk, we will look at the atomic gas-to-stellar and stellar-to-halo mass relations from such a new perspective, we will show that such new diagnostics can be used as critical tests for simulations of galaxy formation and evolution, and we will finally discuss an intriguing astrophysical implication.  Welcome!
