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…
Nonabelian Kinetic Mixing in a Confining Phase
Gonzalo Alonso-Álvarez, Ruike Cao, James M. Cline +2
Dark matter from a hidden sector with SU() gauge symmetry can have a nonabelian kinetic mixing portal with the standard model. The dark photon becomes massive in the confining p…
The Flavor of QCD Axion Dark Matter
Gonzalo Alonso-Álvarez, James M. Cline, Tianzhuo Xiao
We argue that demanding a consistent cosmological history, including the absence of domain walls and strongly interacting relics at the Peccei-Quinn scale, singles out two concrete…
Blazar constraints on neutrino-dark matter scattering
James M. Cline, Shan Gao, Fangyi Guo +5
Neutrino emission in coincidence with gamma rays has been observed from the blazar TXS 0506+056 by the IceCube telescope. Neutrinos from the blazar had to pass through a dense spik…
