This is a talk held during the regular colloquium series (usually Tuesdays at 4pm).
While our present picture for the formation of galactic disks can be largely traced to analytic ideas first explored in the 1980s, where a galactic disk’s angular momentum is tied to the angular momentum of its host dark matter halo, our understanding of galaxy disk formation remains incomplete.
Astronomical transients are signposts of catastrophic events in space, including the most extreme stellar deaths, stellar tidal disruptions by supermassive black holes, and mergers of compact objects.
Normalizing Flows (NF) are bijective maps from the data to a Gaussian (normal) distribution or viceversa. In contrast to other generative models they are lossless and provide data likelihood via the Jacobian of the transformation.
Betelgeuse's "Great Dimming" in the winter of 2020 quickly became a source of fascination for both professional and amateur astronomers.
The rarest galaxies formed early in the Universe’s history pose unique problems for galaxy formation and evolution in a Lambda-CDM universe. I will discuss two separate observational campaigns — one with ALMA and one with JWST — aimed at finding and characterizing massive (M*>10^10 Msun) gala
