More accurate gravitational wave backgrounds from cosmic strings
Jeremy M. Wachter, Ken D. Olum, Jose J. Blanco-Pillado
We derive a general procedure for calculating the gravitational wave background (GWB) from cosmic string loops whose typical shape evolves over time, as in gravitational backreacti…
Effective Actions for Domain Wall Dynamics
Jose J. Blanco-Pillado, Alberto García Martín-Caro, Daniel Jiménez-Aguilar +1
We introduce a systematic method to derive the effective action for domain walls directly from the scalar field theory that gives rise to their solitonic solutions. The effective a…
Numerical gravitational backreaction on cosmic string loops from simulation
Jeremy M. Wachter, Ken D. Olum, Jose J. Blanco-Pillado +2
We report on the results of performing computational gravitational backreaction on cosmic string loops taken from a network simulation. The principal effect of backreaction is to s…
Global String Instantons
Jose J. Blanco-Pillado, Georgios Fanaras, Alexander Vilenkin
We study the formation of gravitating global strings through quantum mechanical tunneling. The instantons that describe the nucleation process are characterized by two parameters:…
Tunneling Potentials to Nothing
J. J. Blanco-Pillado, J. R. Espinosa, J. Huertas +1
The catastrophic decay of a spacetime with compact dimensions, via bubbles of nothing (BoNs), is probably a generic phenomenon. BoNs admit a 4-dimensional description as singular C…
The NANOGrav 15-year Data Set: Search for Signals from New Physics
Adeela Afzal, Gabriella Agazie, Akash Anumarlapudi +120
The 15-year pulsar timing data set collected by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) shows positive evidence for the presence of a low-freque…
