The Simons Observatory: Assessing the Impact of Dust Complexity on the Recovery of Primordial -modes
Yiqi Liu, Susanna Azzoni, Susan E. Clark +14
We investigate how dust foreground complexity can affect measurements of the tensor-to-scalar ratio, , in the context of the Simons Observatory, using a cross-spectrum component…

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…

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…
