Gravitational Wave Opacity from Gauge Field Dark Energy
R. R. Caldwell, C. Devulder
We show that astrophysical gravitational waves can undergo an anomalous modulation when propagating through cosmic gauge field dark energy. A sufficiently strong effect, dependent…
Axion Gauge Field Inflation and Gravitational Leptogenesis: A Lower Bound on B Modes from the Matter-Antimatter Asymmetry of the Universe
R. R. Caldwell, C. Devulder
We present a toy model of an axion gauge field inflation scenario that yields viable density and gravitational wave spectra. The scenario consists of an axionic inflaton in a steep…
Gravitational Wave -- Gauge Field Dynamics
R. R. Caldwell, C. Devulder, N. A. Maksimova
The dynamics of a gravitational wave propagating through a cosmic gauge field are dramatically different than in vacuum. We show that a gravitational wave acquires an effective mas…
Gravitational Wave - Gauge Field Oscillations
R. R. Caldwell, C. Devulder, N. A. Maksimova
Gravitational waves propagating through a stationary gauge field transform into gauge field waves and back again. When multiple families of flavor-space locked gauge fields are pre…
