Massive star formation in W51A triggered by cloud-cloud collisions
Shinji Fujita, Kazufumi Torii, Nario Kuno +18
W51A is one of the most active star-forming region in our Galaxy, which contains giant molecular clouds with a total mass of 10^6 Msun. The molecular clouds have multiple velocity…
Evolution of Molecular Clouds in the Superwind Galaxy NGC 1808 Probed by ALMA Observations
Dragan Salak, Yuto Tomiyasu, Naomasa Nakai +3
ALMA imaging of the cold molecular medium in the nearby starburst galaxy NGC 1808 is presented. The observations reveal the distribution of molecular gas, traced by CO (1-0)…
Diverse nuclear star-forming activities in the heart of NGC 253 resolved with ten-pc scale ALMA images
Ryo Ando, Kouichiro Nakanishi, Kotaro Kohno +13
We present an 8 pc x 5 pc resolution view of the central ~ 200 pc region of the nearby starburst galaxy NGC 253, based on ALMA Band 7 (λ ~ 0.85 mm or ν ~ 350 GHz) observations cove…
Large-scale CO J=1-0 observations of the giant molecular cloud associated with the infrared ring N35 with the Nobeyama 45-m telescope
Kazufumi Torii, Shinji Fujita, Mitsuhiro Matsuo +14
We report an observational study of the giant molecular cloud (GMC) associated with the Galactic infrared ring-like structure N35 and two nearby HII regions G024.392+00.072 (HII re…
FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) I: Project Overview and Initial Results
Tomofumi Umemoto, Tetsuhiro Minamidani, Nario Kuno +41
The FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) project is one of the legacy projects using the new multi-beam FOREST receiver installed…
FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) 2: Possible evidence for formation of NGC~6618 cluster in M17 by cloud-cloud collision
Atsushi Nishimura, Tetsuhiro Minamidani, Tomofumi Umemoto +15
We present CO 1--0, CO 1--0 and CO 1--0 images of the M17 giant molecular clouds obtained as part of FUGIN (FOREST Ultra-wide Galactic Plane Survey…
FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) : Molecular clouds toward W33 ; possible evidence for a cloud-cloud collision triggering O star formation
Mikito Kohno, Kazufumi Torii, Kengo Tachihara +14
We observed molecular clouds in the W33 high-mass star-forming region associated with compact and extended HII regions using the NANTEN2 telescope as well as the Nobeyama 45-m tele…
CO observations of the molecular gas in the galactic HII region Sh2-48; Evidence for cloud-cloud collision as a trigger of high-mass star formation
Kazufumi Torii, Yusuke Hattori, Mitsuhiro Matsuo +15
Sh2-48 is a Galactic HII region located at 3.8 kpc with an O9.5-type star identified at its center. As a part of the FOREST Unbiased Galactic plane Imaging survey using the Nobeyam…
Discovery of a distant molecular cloud in the extreme outer Galaxy with the Nobeyama 45-m telescope
Mitsuhiro Matsuo, Hiroyuki Nakanishi, Tetsuhiro Minamidani +10
We report the discovery of the molecular cloud whose kinematic distance is the largest in the Galaxy at the present moment, named G213.0420.003, at 213.042 and $b…
Variation in GMC Association Properties Across Bars, Spiral Arms, Inter-Arms, and Circumnuclear Region of M100 (NGC 4321) Extracted from ALMA Observations
Hsi-An Pan, Nario Kuno
We study the physical properties of giant molecular cloud associations (GMAs) in M100 (NGC 4321) using the ALMA Science Verification feathered (12-m+ACA) data in 12CO (1-0). To exa…
