Less isn't more: Cosmological bounds on the neutrino masses are robust to changes in the neutrino abundance
Sebastian J. Figueroa, Alexander C. Sobotka, Adrienne L. Erickcek
We investigate how neutrino-mass constraints from cosmology depend on the assumed thermal history of the universe. Photon injection after neutrino decoupling would decrease the neu…
Signatures of Very Early Dark Energy in the Matter Power Spectrum
Alexander C. Sobotka, Adrienne L. Erickcek, Tristan L. Smith
Axion-like scalar fields can induce temporary deviations from the standard expansion history of the universe. The scalar field's contribution to the energy density of the universe…
Comprehensive Constraints on Dark Radiation Injection After BBN
Alexander C. Sobotka, Adrienne L. Erickcek, Tristan L. Smith
We derive constraints on the injection of free-streaming dark radiation after big bang nucleosynthesis (BBN) by considering the decay of a massive hidden sector particle into dark…
