This is a talk held during the regular colloquium series (usually Tuesdays at 4pm).
Self-interactions of dark matter could solve the “small-scale problems” of the cold dark matter paradigm. They are ubiquitous when dark matter is part of dark sectors.
Given its proximity, the solar neighborhood has long been considered a fundamental laboratory for understanding how stars form.
The filamentary network of intergalactic medium (IGM) gas that gives origin to the "Lyman-α forest" encodes information on the physics of structure formation and the early thermodynamics of diffuse baryonic material.
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.
The epoch of reionization (EoR) was a landmark event, when radiation from the first stars and accreting black holes permeated the intergalactic medium (IGM) and ionized hydrogen.
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.
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
Large-scale photometric, spectroscopic, and astrometric surveys have revolutionized our understanding of the Milky Way and its satellite systems.
As astronomers near the commissioning of the extremely large telescopes, the Rubin Observatory, as well as new space-based observatories like the Roman Space Telescope and JWST to peer more deeply into our Universe, our community is challenged to develop a theoretical and modeling framework to ch
