Cosmological Neutron Stars Produce Diffuse Axion X-Ray Signatures
Orion Ning, Kailash Raman, Benjamin R. Safdi
Axion-like particles can be abundantly produced through scattering processes in the cores of neutron stars (NSs). If they are ultralight ( eV), then they can…

Axion lines from nuclear de-excitations in galactic stellar populations
Orion Ning, Anupam Ray, Benjamin R. Safdi
We show that mono-energetic axions are produced in abundance through nuclear de-excitations in nearby galaxies such as M87, which is the central galaxy of the Virgo cluster, and th…

Probing the Axion-Electron Coupling with NuSTAR Observations of Galaxies
Orion Ning, Benjamin R. Safdi
We search for the existence of ultralight axions coupling to electrons and photons using data from the NuSTAR telescope directed toward the galaxies M82, M87, and M31. We focus on…
