Searching for Axion-like particle Dark Matter with Time-domain Polarization: Constraints from a protoplanetary disk

Kanako Narita, Tomohiro Fujita, Ryo Tazaki +1

Axion-like particles (ALPs) can induce a birefringence effect that rotates the polarization angle of light, offering a probe of ultralight dark matter. We analyze archival near-inf…
