Do Pulsar Timing Datasets Favor Massive Gravity?
Chris Choi, Tina Kahniashvili
Several observational phenomena suggest that the standard model of cosmology and particle physics requires revision. To address this, we consider the extension of general relativit…

Stochastic gravitational wave background detection using NANOGrav 15-year data set in the context of massive gravity
Chris Choi, Jacob Magallanes, Murman Gurgenidze +1
Convincing evidence of a stochastic gravitational wave (GW) background has been found by the NANOGrav Collaboration in the 15-year data set. From this signal, we can evaluate the p…
