Tracing the gravitational potential using cosmic voids
Seshadri Nadathur, Shaun Hotchkiss, Robert Crittenden
The properties of large underdensities in the distribution of galaxies in the Universe, known as cosmic voids, are potentially sensitive probes of fundamental physics. We use data…
Can a supervoid explain the Cold Spot?
Seshadri Nadathur, Mikko Lavinto, Shaun Hotchkiss +1
The discovery of a void of size Mpc and average density contrast of aligned with the Cold Spot direction has been recently reported. It has been argued…
Self-similarity and universality of void density profiles in simulation and SDSS data
S. Nadathur, S. Hotchkiss, J. M. Diego +4
The stacked density profile of cosmic voids in the galaxy distribution provides an important tool for the use of voids for precision cosmology. We study the density profiles of voi…
The Jubilee ISW Project II: observed and simulated imprints of voids and superclusters on the cosmic microwave background
S. Hotchkiss, S. Nadathur, S. Gottlöber +4
We examine the integrated Sachs-Wolfe (ISW) imprint of voids and superclusters on the cosmic microwave background. We first study results from the Jubilee -body simulation. From…
