Head-tail molecular clouds falling onto the Milky Way disk
Mikito Kohno, Yasuo Fukui, Takahiro Hayakawa +13
We report discovery of two CO clouds which are likely falling down to the Galactic plane at more than km s. The clouds show head-tail distributions elongated perpendicu…
Infrared bubble recognition in the Milky Way and beyond using deep learning
Shimpei Nishimoto, Toshikazu Onishi, Atsushi Nishimura +9
We propose a deep learning model that can detect Spitzer bubbles accurately using two-wavelength near-infrared data acquired by the Spitzer Space Telescope and JWST. The model is b…
Massive star formation in the Carina nebula complex and Gum 31 -- II. a cloud-cloud collision in Gum 31
Shinji Fujita, Hidetoshi Sano, Rei Enokiya +10
We present the results of analyses of the 12CO (J=1-0), 13CO (J=1-0), and 12CO (J=2-1) emission data toward Gum 31. Three molecular clouds separated in velocity were detected at -2…
Development of a new wideband heterodyne receiver system for the Osaka 1.85-m mm-submm telescope -- Corrugated horn & Optics covering 210-375 GHz band
Yasumasa Yamasaki, Sho Masui, Hideo Ogawa +21
The corrugated horn is a high performance feed often used in radio telescopes. There has been a growing demand for wideband optics and corrugated horns in millimeter and submillime…
Development of a new wideband heterodyne receiver system for the Osaka 1.85-m mm-submm telescope -- Receiver development & the first light of simultaneous observation in 230GHz and 345GHz bands with an SIS-mixer with 4-21GHz IF output
Sho Masui, Yasumasa Yamasaki, Hideo Ogawa +22
We have developed a wideband receiver system for simultaneous observations in CO lines of J = 2-1 and J = 3-2 transitions using the Osaka 1.85-m mm-submm telescope. As a frequency…
Observational demonstration of a low-cost fast Fourier transform spectrometer with a delay-line-based ramp-compare ADC implemented on FPGA
Atsushi Nishimura, Takeru Matsumoto, Teppei Yonetsu +5
In this study, a novel type of Fourier transform radio spectrometer (termed as all-digital radio spectrometer; ADRS) has been developed in which all functionalities comprising a ra…
