Limits on the size of electron density fluctuations in the early universe and implications for the Hubble tension
Gabriel P. Lynch, Jens Chluba, Richard Battye +1
Little is known about the early universe on scales smaller than those resolved by the cosmic microwave background (CMB), where electron density fluctuations on kiloparsec to megapa…
Peering Beyond the Veil of Last Scattering: A View of the Universe with CMB Spectral Distortions
Bryce Cyr, Nabila Aghanim, Ethan Baker +37
The frequency spectrum of the cosmic microwave background is the most precise blackbody ever measured in nature, with deviations constrained at the level of almost one part per mil…
Self-field of a moving string
Richard A. Battye, Lukasz P. Bunio, Steven J. Cotterill
We discuss the effectiveness of the recently proposed quantity in suppressing the contribution of a string's self-field to its spectrum, which is used in field theory simul…
Evolution of Cosmic String Loops under Gravitational Backreaction
Lasse Gerblich, Richard A. Battye, E. P. S. Shellard
Nambu-Goto cosmic string loops generically develop cusps, points where the string momentarily reaches the speed of light. These cusps produce strong gravitational wave bursts with…
Kinky vortons in the 2HDM
Richard A. Battye, Steven J. Cotterill, Adam K. Thomasson
We construct and analyse two-dimensional, current-carrying ring solutions, known as kinky vortons, in the -symmetric global two-Higgs-doublet model (2HDM). We demonst…
