Secondary Production of Photons from ALP Dark Matter interacting with a Cosmological Magnetic Field
Abdias Aires, Robert Brandenberger, Ashu Kushwaha
Under the assumption that dark matter is a coherently oscillating pseudoscalar field coupled to electromagnetism by the usual Chern-Simons term, we study the production of secondar…

Mitigation of nonlinear galaxy bias with a theoretical-error likelihood
Abdias Aires, Nickolas Kokron, Rogerio Rosenfeld +2
Stage-IV galaxy surveys will measure correlations at small cosmological scales with high signal-to-noise ratio. One of the main challenges of extracting information from small scal…
