Resonant Gravitational Production of Chiral Dark Photons
Leah Jenks, Marc Kamionkowski, Edward W. Kolb
Vector fields with a chiral, parity-odd coupling to a pseudoscalar field are known to undergo resonant amplification. In this work, we study this phenomenon in the context of cosmo…
Nonthermal leptogenesis via cosmological gravitational particle production is tested by inflationary gravitational waves
Tammi Chowdhury, Leah Jenks, Edward W. Kolb +2
We explore the coincidence of scales between cosmic inflation and right-handed neutrinos in seesaw models. We show that inflation models, which will be tested by next-generation CM…
Gravitational-Wave Propagation Through the Axiverse
Leah Jenks, Marc Kamionkowski
We study the effects of oscillating, ultralight scalar and pseudoscalar fields on the propagation of gravitational waves (GWs). We consider two potential couplings of the (pseudo)s…
Higgs Inflation: Particle Factory
Tammi Chowdhury, Leah Jenks, Edward W. Kolb +1
We study cosmological gravitational particle production (CGPP) in Higgs inflation, wherein the inflaton is a scalar field with quartic self-coupling and a nonminimal coupling t…
Gravitational Particle Production of Scalars: Analytic and Numerical Approaches Including Early Reheating
Leah Jenks, Edward W. Kolb, Keyer Thyme
Cosmological gravitational particle production (GPP) is a generic mechanism by which particles are produced during the inflationary epoch. In this work we consider the GPP of massi…
Parity-breaking galaxy 4-point function from lensing by chiral gravitational waves
Keisuke Inomata, Leah Jenks, Marc Kamionkowski
Recent searches for parity breaking in the galaxy four-point correlation function, as well as the prospects for greatly improved sensitivity to parity breaking in forthcoming surve…
Gravitational Production of Completely Dark Photons with Nonminimal Couplings to Gravity
Christian Capanelli, Leah Jenks, Edward W. Kolb +1
Dark photons are a theorized massive spin-1 particle which can be produced via various mechanisms, including cosmological gravitational particle production (GPP) in the early unive…
Runaway Gravitational Production of Dark Photons
Christian Capanelli, Leah Jenks, Edward W. Kolb +1
We demonstrate that gravitational particle production (GPP) of a massive, Abelian, vector (Proca) field during inflation in the presence of nonminimal coupling to gravity may suffe…
Dark Matter Isocurvature from Curvature
Ian Holst, Wayne Hu, Leah Jenks
Isocurvature fluctuations, where the relative number density of particle species spatially varies, can be generated from initially adiabatic, or curvature, fluctuations if the vari…
Cosmological Implications of Kalb-Ramond-Like-Particles
Christian Capanelli, Leah Jenks, Edward W. Kolb +1
The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most notably appears in the context of string theory, but has largely been unexplored in the context of cosmo…
