DESCRIPTION:Recent JWST and ALMA observations have revealed that a substant
 ial fraction of galaxies at very high redshift are rotationally supported d
 isks. Many of these systems host kinematically cold\, or “settled\,” gaseou
 s disks\, a finding that stands in tension with the expectations of many ga
 laxy-formation models. In this seminar\, I will present an overview of cosm
 ological simulations of disk-galaxy formation. I will discuss the propertie
 s of gas-rich\, high-redshift disks\, their turbulent nature\, and how thes
 e early phases of disk assembly connect to spectroscopic and astrometric ob
 servations of the Milky Way. Finally\, I will show new results indicating t
 hat turbulent\, early-Universe galaxies are more susceptible to global grav
 itational instabilities\, such as bar formation\, than previously thought. 
 These results carry important implications for the rapid buildup of galacti
 c bulges and the fueling of central black holes. To arrange a visit with th
 e speaker during the visit\, please contact their host: Eva Schinnerer\n\nI
