Upper Limit on the QCD Axion Mass from Isolated Neutron Star Cooling
Malte Buschmann, Christopher Dessert, Joshua W. Foster +2
The quantum chromodynamics (QCD) axion may modify the cooling rates of neutron stars (NSs). The axions are produced within the NS cores from nucleon bremsstrahlung and, when the nu…
Dark Matter from Axion Strings with Adaptive Mesh Refinement
Malte Buschmann, Joshua W. Foster, Anson Hook +4
Axions are hypothetical particles that may explain the observed dark matter (DM) density and the non-observation of a neutron electric dipole moment. An increasing number of axion…
The Galactic potential and dark matter density from angular stellar accelerations
Malte Buschmann, Benjamin R. Safdi, Katelin Schutz
We present an approach to measure the Milky Way (MW) potential using the angular accelerations of stars in aggregate as measured by astrometric surveys like Gaia. Accelerations dir…
