The effect of photoionising feedback on star formation in isolated and colliding clouds
Kazuhiro Shima, Elizabeth J. Tasker, Christoph Federrath +1
We investigate star formation occurring in idealised giant molecular clouds, comparing structures that evolve in isolation versus those undergoing a collision. Two different collis…
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…
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…
Formation of Massive, Dense Cores by Cloud-Cloud Collisions
Ken Takahira, Kazuhiro Shima, Elizabeth J. Tasker +1
We performed sub-parsec ( 0.014 pc) scale simulations of cloud-cloud collisions of two idealized turbulent molecular clouds (MCs) with different masses in the range of $0.76…
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…
A new look at the molecular gas in M42 and M43; possible evidence for cloud-cloud collision which triggered formation of the OB stars in the Orion Nebula Cluster
Yasuo Fukui, Kazufumi Torii, Yusuke Hattori +10
The Orion Nebula Cluster toward the HII region M42 is the most outstanding young cluster at the smallest distance 410pc among the rich high-mass stellar clusters. By newly analyzin…
