Numerical Analysis of Resonant Axion-Photon Mixing: Part I
Estanis Utrilla Ginés, Dion Noordhuis, Christoph Weniger +1
Many present-day axion searches attempt to probe the mixing of axions and photons, which occurs in the presence of an external magnetic field. While this process is well-understood…
Axion Clouds around Neutron Stars
Dion Noordhuis, Anirudh Prabhu, Christoph Weniger +1
Recent work has shown that axions can be efficiently produced via non-stationary pair plasma discharges in the polar cap region of pulsars. Here, we point out that for axion masses…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
Novel Constraints on Axions Produced in Pulsar Polar-Cap Cascades
Dion Noordhuis, Anirudh Prabhu, Samuel J. Witte +3
Axions can be copiously produced in localized regions of neutron star magnetospheres where the ambient plasma is unable to efficiently screen the induced electric field. As these a…
Astrophysical and Cosmological Probes of Dark Matter
Kimberly K. Boddy, Mariangela Lisanti, Samuel D. McDermott +16
While astrophysical and cosmological probes provide a remarkably precise and consistent picture of the quantity and general properties of dark matter, its fundamental nature remain…
Axion-Photon Conversion in Neutron Star Magnetospheres: The Role of the Plasma in the Goldreich-Julian Model
Samuel J. Witte, Dion Noordhuis, Thomas D. P. Edwards +1
The most promising indirect search for the existence of axion dark matter uses radio telescopes to look for narrow spectral lines generated from the resonant conversion of axions i…
