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…
The Secret Higgstory of the Highest Temperature during Reheating
Samuel Passaglia, Wayne Hu, Andrew J. Long +1
We study the role of the Standard Model Higgs condensate, formed during cosmological inflation, in the epoch of reheating that follows. We focus on the scenario where the inflaton…
No evidence for axions from Chandra observation of magnetic white dwarf
Christopher Dessert, Andrew J. Long, Benjamin R. Safdi
Ultralight axions with axion-photon couplings GeV may resolve a number of astrophysical anomalies, such as unexpected ~TeV transpare…
Dipole Radiation and Beyond from Axion Stars in Electromagnetic Fields
Mustafa A. Amin, Andrew J. Long, Zong-Gang Mou +1
We investigate the production of photons from coherently oscillating, spatially localized clumps of axionic fields (oscillons and axion stars) in the presence of external electroma…
