Dust plays a central role in regulating astrophysical
environments across a wide range of scales. In active galactic
nuclei (AGN), radiation pressure on dust launches large-scale winds
that couple energy from the black hole to the surrounding
galaxy...
Supermassive black hole binaries (SMBHBs) should be common in
galactic nuclei as a result of frequent galaxy mergers. Yet they
remain undetectable, especially during the final stage of their
evolution. At this stage, SMBHBs are expected to emit...
Abstract: The uniqueness of the Kerr-de Sitter
family of black hole spacetimes as stationary solutions to
the Einstein vacuum equations is a crucial ingredient to
understanding the final states of positive cosmological
constant universes, such as...
I will discuss the current status of DESI-1, some forecasts for
the next set of cosmological constraints from DESI and highlight
the southern expansion of the footprint happening between now and
December 2028. Then I will present the current plans...
