Abstract: Most cosmological data analysis
today relies on the Friedmann-Lemaitre-Robertson-Walker (FLRW)
metric, which provides the basis of the current standard
cosmological model. Within this framework, interesting tensions
between our...
Abstract: At the center of our Milky Way
Galaxy lives a compact massive object called Sagittarius A* (Sgr
A*) which is believed to be a black hole. Its mass, as inferred
from the orbits of gravitationally bond stars as well as from
direct images...

Abstract: Celestial holography aims to
uncover aspects of a theory of quantum gravity in asymptotically
flat spacetime by studying a putative dual "celestial" conformal
field theory (cCFT) that lives on its boundary. A primary way to do
this is to...

Abstract: A new era in astrophysics was
inaugurated with the 2015 discovery of gravitational waves from the
collision of two black holes in data from the Laser Interferometer
Gravitational-wave Observatory (LIGO). Since then, LIGO and its
sister...
