Probing neutrino interactions and dark radiation with gravitational waves
Marilena Loverde, Zachary J. Weiner
After their generation, cosmological backgrounds of gravitational waves propagate nearly freely but for the expansion of the Universe and the anisotropic stress of free-streaming p…
Nonperturbative structure in coupled axion sectors and implications for direct detection
David Cyncynates, Olivier Simon, Jedidiah O. Thompson +1
Pairs of misalignment-produced axions with nearby masses can experience a nonlinear resonance that leads to enhanced direct and astrophysical signatures of axion dark matter. In mu…
The Physics of Light Relics
Cora Dvorkin, Joel Meyers, Peter Adshead +19
Many well-motivated extensions of the Standard Model predict the existence of new light species that may have been produced in the early universe. Prominent examples include axions…
