CMB Birefringence from Axion String Networks Calibrated to an AMR Simulation
Mustafa A. Amin, Mudit Jain, Andrew J. Long +3
A cosmological network of axion strings may exist in the Universe today. If axion-like particles couple to electromagnetism, such a network induces spatially varying birefringence…

Extracting Axion String Network Parameters from Simulated CMB Birefringence Maps using Convolutional Neural Networks
Ray Hagimoto, Andrew J. Long, Mustafa A. Amin
Axion-like particles may form a network of cosmic strings in the Universe today that can rotate the plane of polarization of cosmic microwave background (CMB) photons. Future CMB o…

Vector Wave Dark Matter and Terrestrial Quantum Sensors
Dorian W. P. Amaral, Mudit Jain, Mustafa A. Amin +1
(Ultra)light spin- particles -- dark photons -- can constitute all of dark matter (DM) and have beyond Standard Model couplings. This can lead to a coherent, oscillatory signatu…
