Photonic Freeze-In
Peter Cox, Matthew J. Dolan, Frederick J. Hiskens
We present a new scenario of freeze-in, where the dark matter is produced exclusively via the annihilation of photons. We study fermionic and scalar dark matter models with a focus…
Constraining Dark Photons with Self-consistent Simulations of Globular Cluster Stars
Matthew J. Dolan, Frederick J. Hiskens, Raymond R. Volkas
We revisit stellar constraints on dark photons. We undertake dynamical stellar evolution simulations which incorporate the resonant and off-resonant production of transverse and lo…
Advancing Globular Cluster Constraints on the Axion-Photon Coupling
Matthew J. Dolan, Frederick J. Hiskens, Raymond R. Volkas
We improve the current upper bound on the axion-photon coupling derived from stellar evolution using the parameter, the ratio of stellar populations on the Asymptotic Giant B…
Constraining axion-like particles using the white dwarf initial-final mass relation
Matthew J. Dolan, Frederick J. Hiskens, Raymond R. Volkas
Axion-like particles (ALPs), a class of pseudoscalars common to many extensions of the Standard Model, have the capacity to drain energy from the interiors of stars. Consequently,…
