By precisely measuring the motions stars on the sky over time,
the Gaia mission is conducting a comprehensive census of the Milky
Way's binary stars. These data are transformative both for
population modeling and for discovery of rare objects. I...
The DESI galaxy survey has recently placed the tightest
constraint on the sum of neutrino masses to date. For such effects
“below the detection limit”, where data can only infer upper
bounds, Bayesian and frequentist methods can give important...
Abstract: The holographic principle states that
in the limit of a large number of degrees of freedom, some quantum
systems give rise to an emergent gravitational spacetime with one
more dimension. What are these quantum systems, and which
properties...
Over the past 30 years, nearly 6000 exoplanets have been
discovered, revealing a remarkable diversity of planetary systems.
Essential information about the formation of these systems can be
found in their current architectures, as they serve as a...
The first structures of particle dark matter form by
gravitationally condensing out of the smooth mass distribution of
the early universe. This formation mechanism leaves these "prompt
cusps" with uniquely compact r^-1.5 density profiles and
links...
Established in 1954, the “Conseil Européen pour la Recherche
Nucléaire” or “CERN” has been the leading European laboratory for
accelerator-based studies of the fundamental particles and their
interactions. CERN has hosted several large particle...
Virialized clusters and super-clusters of galaxies, which reside
in massive dark matter halos, are the most rare objects in our
Universe but contain most of its matter. As such, obtaining
accurate measures of large cluster masses will put tight...
Abstract: A remarkable feature of general
relativity is the presence of spacetime singularities. One of the
central aims of a complete theory of (quantum) gravity is to
resolve these singularities. In this talk, I will describe ongoing
work—building...
