MeV dark matter decay forecasts for the COSI mission
Robin Anthony-Petersen, Orion Ning, Yu Watanabe +21
The decay of dark matter (DM) is a generic prediction of many particle physics models, producing distinctive monochromatic signatures in environments such as the Galactic halo. Sea…
No Evidence for Superradiant Axions in LIGO-Virgo-KAGRA GWTC-5 Binary Black Hole Spins
Orion Ning, Benjamin R. Safdi, Catherine Welch
The quantum chromodynamics (QCD) axion and axion-like particles may form bound clouds around spinning black holes (BHs) when their Compton wavelength is comparable to the BH gravit…
Crowdsourcing Gravitational Waves from Superradiant Axions
Sebastian A. R. Ellis, Orion Ning, Nicholas L. Rodd +1
Black hole superradiance is a powerful probe of ultralight axions. If nature contains a boson with a mass of order eV, will lead to…
Blazar Constraints on Axions through New Spectral Modulation Searches in 1ES 1959+650 & B2 1811+31
Andrea Giovanni De Marchi, Orion Ning, Tianzhuo Xiao
Blazars are unique astrophysical environments whose high-energy -ray spectra are susceptible to modulations in the presence of ultralight axions. We search for these modulations…
