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…
Development of TIFUUN: Terahertz Integral Field Units with Universal Nanotechnology
Akira Endo, Tom J. L. C. Bakx, Jochem J. A. Baselmans +50
TIFUUN (THz Integral Field Units with Universal Nanotechnology) is an ultra-wideband mm-submm wave imaging spectrometer that capitalizes on the highly scalable integrated supercond…
Testing masking effectiveness using multi-line image cubes based on COSMOS2020 for [CII] line intensity mapping at
J. Clarke, C. Karoumpis, A. Dev +5
We created line intensity mapping intensity cubes for CO and [CII] emission lines using the COSMOS2020 galaxy catalogue, forming predictions based on empirical data, for observatio…
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…
