Isolating signatures of major cloud-cloud collisions - II. The lifetimes of broad bridge features
(2015-12-01)
We investigate the longevity of broad bridge features in position–velocity diagrams that appear as a result of cloud–cloud collisions. Broad bridges will have a finite lifetime due to the action of feedback, conversion of ...
STARBENCH: the D-type expansion of an H II region
(2015-10-21)
STARBENCH is a project focused on benchmarking and validating different star formation and stellar feedback codes. In this first STARBENCH paper we perform a comparison study of the D-type expansion of an H II region. The ...
The dangers of being trigger-happy
(2015-06-21)
We examine 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. We compile a catalogue ...
Isolating signatures of major cloud-cloud collisions using position-velocity diagrams
(2015-06-01)
Collisions between giant molecular clouds are a potential mechanism for triggering the formation of massive stars, or even super star clusters. The trouble is identifying this process observationally and distinguishing it ...
