Unlocking the Hidden Potential of ALMA Calibrators: A Pilot Blind Search for Galactic Molecular Gas in ALMA Band 1
Kanako Narita, Bunyo Hatsukade
We present a pilot blind absorption line search using calibrator observations with the Atacama Large Millimeter/submillimeter Array (ALMA) Band 1 receiver (35 GHz to 50 GHz). Radio…

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…

ALMA Lensing Cluster Survey: Molecular Gas Properties of Line-Emitting Galaxies from a Blind Survey
Kanako Narita, Bunyo Hatsukade, Seiji Fujimoto +16
We present results of a blind search for line-emitting galaxies using ALMA Lensing Cluster Survey data. We detected seven line emitters, one of which is [C\,{\sc ii}] at $z = 6.071…
