Discovery of molecular and atomic clouds associated with the gamma-ray supernova remnant Kesteven 79
M. Kuriki, H. Sano, N. Kuno +21
We carried out CO( = 1-0) observations of the Galactic gamma-ray supernova remnant (SNR) Kesteven 79 using the Nobeyama Radio Observatory 45 m radio telescope, which has…
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…
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…
Molecular and Atomic Clouds toward the Wolf-Rayet Nebula NGC 2359: Possible Evidence for Isolated High-Mass Star Formation Triggered by a Cloud-Cloud Collision
Hidetoshi Sano, Katsuhiro Hayashi, Rei Enokiya +17
NGC 2359 is an HII region located in the outer Galaxy that contains the isolated Wolf-Rayet (WR) star HD 56925. We present millimeter/submillimeter observations of CO( =…
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…
Molecular clouds toward three Spitzer bubbles S116, S117 and S118: Evidence for the cloud-cloud collision which formed the three \HII \ regions and a 10-pc scale molecular cavity
Yasuo Fukui, Akio Ohama, Mikito Kohno +6
We carried out a molecular line study toward the three Spitzer bubbles S116, S117 and S118 which show active formation of high-mass stars. We found molecular gas consisting of two…
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…
High-mass star formation possibly triggered by cloud-cloud collision in the HII region RCW 34
Katsuhiro Hayashi, Hidetoshi Sano, Rei Enokiya +12
We report a possibility that the high-mass star located in the HII region RCW 34 was formed by a triggering induced by a collision of molecular clouds. Molecular gas distributions…
RCW 36 in the Vela Molecular Ridge: Evidence for a high-mass star cluster formation triggered by Cloud-Cloud Collision
Hidetoshi Sano, Rei Enokiya, Katsuhiro Hayashi +21
A collision between two molecular clouds is one possible candidate for high-mass star formation. The HII region RCW 36, located in the Vela molecular ridge, contains a young star c…
High-mass star formation in Orion possibly triggered by cloud-cloud collision III, NGC2068 and NGC2071
Shinji Fujita, Daichi Tsutsumi, Akio Ohama +12
Using the NANTEN2 Observatory, we carried out a molecular line study of high-mass star forming regions with reflection nebulae, NGC 2068 and NGC 2071, in Orion in the 13CO(J=2-1) t…
Molecular gas in the compact H{\sc ii} region RCW 166; possible evidence for an early phase of cloud-cloud collision prior to the bubble formation
Akio Ohama, Mikito Kono, Shinji Fujita +8
Young HII regions are an important site to study O star formation based on distributions of ionized and molecular gas. We revealed that two molecular clouds at km s$^{-1}…
