Pushing the frontiers of gravitational encounters and collisionless dynamics
The long range nature of gravity complicates the dynamics of self-gravitating many-body systems such as galaxies and dark matter (DM) halos. Relaxation/equilibration of perturbed galaxies and cold dark matter halos...

Cosmology and astrophysics with the extragalactic light: background and fluctuations
Cosmology and astrophysics with the extragalactic light: background and fluctuations Abstract: The aggregate light emitted by all extragalactic sources can be measured either as an absolute intensity or through its...

Gabriela González, Louisiana State University
Albert Einstein predicted a century ago the existence of gravitational waves – ripples in the fabric of spacetime moving at the speed of light. It was believed that these ripples...

Cosmology with Massive Neutrinos
Ghostly neutrino particles continue to bring surprises to fundamental physics, from their existence to the phenomenon of neutrino oscillation which implies that their masses are nonzero. Their exact masses, among...

New probes of fundamental physics: Utilising small-scale signatures in the Universe.
The influx of new and high-quality cosmological data from upcoming cosmic microwave background (CMB) and large-scale structure surveys will provide unique and exciting opportunities to study the fundamental constituents of...

Neutrino mass and cosmic flows
Neutrinos are established to be massive and the mass differences have been measured, but the absolute neutrino mass values remain unknown. Cosmic neutrinos with finite mass slightly suppress the matter...

Cosmology from Condensed Matter Physics: A study of out-of-equilibrium physics
In this work, our prime focus is to study the one to one correspondence between the conduction phenomena in electrical wires with impurity and the scattering events responsible for particle...

Cosmology and cosmography from peculiar velocities in the nearby Universe
Maps of the mass density field can be used to predict peculiar velocities point-by-point. The comparison of these predictions to peculiar velocity data can be used to determine the cosmological...
