Forward cascade of large-scale primordial magnetic fields during structure formation
Molly Abramson, Emma Clarke, Tina Kahniashvili +3
The origin of large scale magnetic fields in the Universe is widely thought to be from early Universe processes, like inflation or phase transitions. These magnetic fields evolve v…
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…
Connecting Inflation to the NANOGrav 15-year Data Set via Massive Gravity
Ved Kenjale, Tina Kahniashvili
Several pulsar timing array (PTA) missions have reported convincing evidence of a stochastic gravitational wave background within their latest datasets. This background could origi…
Intergalactic medium rotation measure of primordial magnetic fields
Salome Mtchedlidze, Paola Domínguez-Fernández, Xiaolong Du +5
The Faraday rotation effect, quantified by the Rotation Measure (RM), is a powerful probe of the large-scale magnetization of the Universe - tracing magnetic fields not only on gal…
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…
Relic Gravitational Waves from the Chiral Plasma Instability in the Standard Cosmological Model
Axel Brandenburg, Emma Clarke, Tina Kahniashvili +2
In the primordial plasma, at temperatures above the scale of electroweak symmetry breaking, the presence of chiral asymmetries is expected to induce the development of helical hype…
