ALP Dark Matter, Cosmological Magnetic Fields and the Direct Collapse Black Hole Formation Scenario
Ashu Kushwaha, Robert Brandenberger
Assuming that dark matter is an ultralight pseudoscalar particle which couples to electromagnetism like an axion (an ALP), we demonstrate that the coupling of the cosmological magn…

An upper limit on cosmological chiral gravitational wave background
Mohammad Ali Gorji, Ashu Kushwaha, Teruaki Suyama
Within the standard framework in which electroweak sphaleron processes relate lepton and baryon number, we derive an upper limit on the amplitude of a chiral gravitational wave bac…

Helical magnetic fields from Riemann coupling lead to baryogenesis
Ashu Kushwaha, S. Shankaranarayanan
The spectrum of energy density fluctuations, baryon asymmetry, and coherent large-scale magnetic fields are the three observables that provide crucial information on physics at ver…
