In our exciting era of experimental cosmology,
rapid developments in instrumentation and highly sensitive
superconducting detectors have provided a wealth of
arcminute-scale cosmic microwave background (CMB) data. These
measurements are transforming...
For more than 15 years, NANOGrav and other pulsar-timing array
collaborations have been carefully monitoring networks of pulsars
across the Milky Way. The goal was to find a tell-tale correlation
signature amid the data from all those pulsars that...
In this talk, I will present a method to remove the effects of
stellar activity from radial velocity measurements.
This method is based on a novel factorization of the measured
spectra to a sum of time independent eigen-spectra convolved with
small...
Abstract: This talk will explore recent
insights into the structure of classical self dual gravity and
non-Kerr-Newman black holes from the study of celestial holography
and scattering amplitudes. “Self dual gravity” refers to a theory
in which the...
The Vera C. Rubin Observatory’s Legacy Survey of Space and Time
(LSST) will constrain our models of the universe through
observations of galaxies and galaxy clusters as well as transients
such as supernovae and strongly lensed quasars. We analyze...
Accretion-powered X-ray pulsars are neutron stars that accrete
matter from a companion star in a binary system, which exhibit
fascinating dynamics. The strong magnetic field of the neutron star
guides material onto the magnetic poles, which are...
