Nobeyama 45 m Local Spur CO survey. I. Giant molecular filaments and cluster formation in the Vulpecula OB association
Mikito Kohno, Atsushi Nishimura, Shinji Fujita +13
We have performed new large-scale CO, CO, and CO 1-0 observations toward the Vulpecula OB association () as part of the Nobeyama 45 m Loca…
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…
Evidence for a Cloud-Cloud Collision in Sh2-233 Triggering the Formation of the High-mass Protostar Object IRAS 05358+3543
R. I. Yamada, Y. Fukui, H. Sano +7
We have carried out a new kinematical analysis of the molecular gas in the Sh2-233 region by using the CO = 2-1 data taken at 0.5 pc resolution. The molecular gas consist…
A Kinematic Analysis of the Giant Molecular Complex W3; Possible Evidence for Cloud-Cloud Collisions that Triggered OB Star Clusters in W3 Main and W3(OH)
R. I. Yamada, H. Sano, K. Tachihara +6
W3 is one of the most outstanding regions of high-mass star formation in the outer solar circle, including two active star-forming clouds, W3 Main and W3(OH). Based on a new analys…
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…
ALMA Observations of Giant Molecular Clouds in M33 III: Spatially Resolved Features of the Star-Formation Inactive Million-solar-mass Cloud
Hiroshi Kondo, Kazuki Tokuda, Kazuyuki Muraoka +16
We present CO ( = 2-1), CO ( = 2-1), and CO ( = 2-1) observations toward GMC-8, one of the most massive giant molecular clouds (GMCs) in M33 using ALM…
