Inverse Gertsenshtein effect as a probe of high-frequency gravitational waves
Yutong He, Sambit K. Giri, Ramkishor Sharma +2
We apply the inverse Gertsenshtein effect, i.e., the graviton-photon conversion in the presence of a magnetic field, to constrain high-frequency gravitational waves (HFGWs). Using…
Modified propagation of gravitational waves from the early radiation era
Yutong He, Alberto Roper Pol, Axel Brandenburg
We study the propagation of cosmological gravitational wave (GW) backgrounds from the early radiation era until the present day in modified theories of gravity. Comparing to genera…
Modified gravity approaches to the cosmological constant problem
The FADE Collaboration, Heliudson Bernardo, Benjamin Bose +5
The cosmological constant and its phenomenology remain among the greatest puzzles in theoretical physics. We review how modifications of Einstein's general relativity could allevia…
Leading-order nonlinear gravitational waves from reheating magnetogeneses
Yutong He, Alberto Roper Pol, Axel Brandenburg
We study the leading-order nonlinear gravitational waves (GWs) produced by an electromagnetic (EM) stress in reheating magnetogenesis scenarios. Both nonhelical and helical magneti…
Simulations of helical inflationary magnetogenesis and gravitational waves
Axel Brandenburg, Yutong He, Ramkishor Sharma
Using numerical simulations of helical inflationary magnetogenesis in a low reheating temperature scenario, we show that the magnetic energy spectrum is strongly peaked at a partic…
Tensor spectrum of turbulence-sourced gravitational waves as a constraint on graviton mass
Yutong He, Axel Brandenburg, Aditya Sinha
We consider a generic dispersive massive gravity theory and numerically study its resulting modified energy and strain spectra of tensor gravitational waves (GWs) sourced by (i) fu…
Can we observe the QCD phase transition-generated gravitational waves through pulsar timing arrays?
Axel Brandenburg, Emma Clarke, Yutong He +1
We perform numerical simulations of gravitational waves (GWs) induced by hydrodynamic and hydromagnetic turbulent sources that might have been present at cosmological quantum chrom…
Relic gravitational waves from the chiral magnetic effect
Axel Brandenburg, Yutong He, Tina Kahniashvili +2
Relic gravitational waves (GWs) can be produced by primordial magnetic fields. However, not much is known about the resulting GW amplitudes and their dependence on the details of t…
