Dissecting the Angular Momentum of Dark Matter Halos

Date posted: February 15th, 2018

Sam Llaneta with Andreas Berlind (Vanderbilt)
Dissecting the Angular Momentum of Dark Matter Halos
We want to test the current theory that the dark matter of a halo imparts its angular momentum on infalling gas, dust, and stars that ultimately forms the disks of galaxies. …Read more.

John Dulin with Glenn Starkman
Hearing the Shape of the Universe
The past few years of work on discerning the topology of the universe have focused on methods like cosmic crystallography and circles-in-the-sky searches, as well as examinations of the correlation matrix to uncover manifolds with non-trivial topology.   …Read more.

The Accelerating Universe and Vacuum Energy

Daniel Pfeffer with Claudia de Rham
The Accelerating Universe and Vacuum Energy

During his senior project, Daniel Pfeffer will investigate the acceleration of the Universe.  He will explore whether or not it is possible to screen the effect of a large vacuum energy and give rise the amount of acceleration currently observed by supernovae and other probes.  …Read more.

Axion Electrodynamics

Michael Sammon with Harsh Mathur
Axion Electrodynamics

Axions were introduced in particle physics in the 1970s to explain CP violation in the standard model. Subsequently axions have become a leading candidate for dark matter in Cosmology. …Read more.
