Dark Photon Polarimetry
Fiesta Ting Yan Leung, Tao Liu, Sida Lu +3
We propose detecting dark photons (DP), a major candidate for wave dark matter, through polarimetry. The DP can modify Maxwell's equations due to its kinetic mixing with regular ph…

Pulsar Polarization Array Limits on Ultralight Axion-like Dark Matter
Xiao Xue, Shi Dai, Hoang Nhan Luu +20
We conduct the first-ever Pulsar Polarization Array (PPA) analysis to detect the ultralight Axion-Like Dark Matter (ALDM) using the polarization data of 22 millisecond pulsars from…
