Journal ArticleDOI
Isolating signatures of major cloud–cloud collisions using position–velocity diagrams
Thomas J. Haworth,Elizabeth J. Tasker,Yasuo Fukui,Kazufumi Torii,James E. Dale,Kazuhiro Shima,Ken Takahira,Asao Habe,Keisuke Hasegawa +8 more
TL;DR: In this paper, a broad bridge feature connecting two intensity peaks, spatially correlated but separated in velocity, is identified as a signature of a high velocity cloud-cloud collision, at least 25Myr after the formation of the first massive (ionising) star.
Journal ArticleDOI
Protoplanetary disc truncation mechanisms in stellar clusters: comparing external photoevaporation and tidal encounters
Andrew J Winter,Cathie J. Clarke,Giovanni P. Rosotti,Jegug Ih,Stefano Facchini,Thomas J. Haworth +5 more
TL;DR: In this paper, the authors compare the effects of photoevaporation and tidal truncation on the distribution of PPD radii in real cluster environments, and show that photo evaporation is always the dominating influence.
Journal ArticleDOI
Triggered O Star Formation in M20 via Cloud–Cloud Collision: Comparisons between High-resolution CO Observations and Simulations
Kazufumi Torii,Yasuki Hattori,Kenji Hasegawa,Akio Ohama,Thomas J. Haworth,Kazuhiro Shima,Asao Habe,Kengo Tachihara,Norikazu Mizuno,Toshikazu Onishi,Akira Mizuno,Yasuo Fukui +11 more
TL;DR: In this paper, the authors presented the new CO J = 1−0 and J = 3−2 observations of the colliding clouds in M20 performed with the Mopra and ASTE telescopes.
Journal ArticleDOI
Isolating signatures of major cloud–cloud collisions – II. The lifetimes of broad bridge features
Thomas J. Haworth,Kazuhiro Shima,Elizabeth J. Tasker,Yasuo Fukui,Kazufumi Torii,James E. Dale,Ken Takahira,Asao Habe +7 more
TL;DR: In this article, the authors investigated the lifetime of broad bridge features in position-velocity diagrams that appear as a result of cloud-cloud collisions and showed that broad bridges will have a finite lifetime due to the action of feedback, conversion of gas into stars and the timescale of the collision.
Journal ArticleDOI
The dangers of being trigger-happy
TL;DR: In this paper, the authors examined the evidence offered for triggered star formation against the backdrop provided by recent numerical simulations of feedback from massive stars at or below giant molecular cloud sizescales, and found that none of the observational markers improved the chances of correctly identifying a given star as triggered by more than factors of two at most.
