Constraints on Axions from a Theoretical Model of Spatially-Extended Gamma-Ray Emission from Neutron Stars
Bijan Berenji
Axions are hypothetical particles proposed to solve the strong CP problem in QCD and may constitute a significant fraction of the dark matter in the Universe. Axions are expected t…

Axion Gamma-Ray Signatures from Quark Matter in Neutron Stars and Gravitational Wave Comparisons
Bijan Berenji
We present a theoretical model for detecting axions from neutron stars in a QCD phase of quark matter. The axions would be produced from a quark-antiquark pair or $d\bar…
