Core-Halo Mass Relation in Cosmological Vector Dark Matter
Jiajun Chen, Yonghao Yao, David J. E. Marsh
We study the cosmological core-halo relation in vector dark matter using three-component Schrödinger-Poisson simulations. Starting from cosmological vector-field initial conditions…
Indirect detection of the QCD axion
Luca Visinelli, Bradley Johnson, Bradley J. Kavanagh +3
The QCD axion, originally proposed to solve the strong CP problem in QCD, is a prominent candidate for dark matter (DM). In the presence of strong magnetic fields, such as those ar…
Vector Dark Matter Halo: From Polarization Dynamics to Direct Detection
Jiajun Chen, Le Hoang Nguyen, David J. E. Marsh
This study investigates the characteristic polarization formation and evolution of vector dark matter (VDM) in the outer halo of galaxies. By employing numerical simulations, we an…
Axions in Andromeda: Searching for Minicluster -- Neutron Star Encounters with the Green Bank Telescope
Liam Walters, Jordan Shroyer, Madeleine Edenton +5
The QCD axion and axion-like particles are compelling candidates for galactic dark matter. Theoretically, axions can convert into photons in the presence of a strong external magne…
Multimessenger signals from compact axion star mergers
Liina Chung-Jukko, Eugene A. Lim, David J. E. Marsh
Axion dark matter can form stable, self-gravitating, and coherent configurations known as axion stars, which are rendered unstable above a critical mass by the Chern-Simons couplin…
