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…
FOREST unbiased Galactic plane imaging survey with the Nobeyama 45 m telescope (FUGIN): Possible evidence of cloud-cloud collisions triggering high-mass star formation in the giant molecular cloud M16 (Eagle Nebula)
Atsushi Nishimura, Shinji Fujita, Mikito Kohno +12
M16, the Eagle Nebula, is an outstanding \HII \ region which exhibits extensive high-mass star formation and hosts remarkable "pillars". We herein obtained new CO 1-0 da…
A kinematic analysis of the CO clouds toward a reflection nebula NGC 2023 observed with the Nobeyama 45 m telescope; Further evidence for a cloud-cloud collision in the Orion region
R. Yamada, R. Enokiya, H. Sano +6
We have analyzed new CO( = 1-0) data in the region of a reflection nebula NGC 2023 with a particular focus on the detailed kinematical properties of the molecular gas. The resul…
High-mass star formation in Orion B triggered by cloud-cloud collision: Merging molecular clouds in NGC 2024
Rei Enokiya, Akio Ohama, Rin Yamada +13
We performed new comprehensive CO(=2--1) observations toward NGC 2024, the most active star forming region in Orion B, with an angular resolution of 100'' obtained…
Molecular gas in a Spitzer bubble N4: possible evidence for cloud-cloud collisions as a trigger of massive star formation
Shinji Fujita, Kazufumi Torii, Kengo Tachihara +18
Herein, we present the 12CO (J=1-0) and 13CO (J=1-0) emission line observations via the FOREST Unbiased Galactic plane Imaging survey with the Nobeyama 45-m telescope (FUGIN) towar…
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…
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) 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…
High-mass star formation in Orion triggered by cloud-cloud collision II, Two merging molecular clouds in NGC2024
Akio Ohama, Daichi Tsutsumi, Hidetoshi Sano +9
We analyzed the NANTEN2 13CO (J=2-1 and 1-0) datasets in NGC 2024. We found that the cloud consists of two velocity components, whereas the cloud shows mostly single-peaked CO prof…
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
