Scaling relations of star-forming regions: from kpc-sized clumps to H II regions
We present the properties of eight star-forming regions, or ‘clumps,’ in three galaxies at z ∼ 1.3 from the WiggleZ Dark Energy Survey, which are resolved with the OH Suppressing InfraRed Imaging Spectrograph (OSIRIS) integral field spectrograph. Within turbulent discs, σ ∼ 90 km s−1, clumps are measured with average sizes of 1.5 kpc and average Jeans masses of 4.2 × 109 M , in total accounting...
متن کاملThe star-forming content of the W3 giant molecular cloud
We have surveyed a ∼0.9-square-degree area of the W3 giant molecular cloud and star-forming region in the 850-μm continuum, using the SCUBA bolometer array on the James Clerk Maxwell Telescope. A complete sample of 316 dense clumps was detected with a mass range from around 13 to 2500M⊙. Part of the W3 GMC is subject to an interaction with the Hii region and fast stellar winds generated by the ...
متن کاملStructure and Conditions in Massive Star Forming Giant Molecular Clouds
Massive stars form in clusters within self-gravitating molecular clouds. The size scale of these clusters is sufficiently large that nonthermal, or turbulent, motions of the gas must be taken into account when considering their formation. Millimeter wavelength radio observations of the gas and dust in these clouds reveal a complex, self-similar structure that reflects the turbulent nature of th...
متن کاملMerging time-scales of stellar sub-clumps in young star-forming regions
Recent observations and hydrodynamical simulations of star formation inside a giant molecular cloud have revealed that, within a star forming region, stars do not form evenly distributed throughout this region, but rather in small sub-clumps. It is generally believed that these subclumps merge and form a young star cluster. The time-scale of this merging process is crucial for the evolution and...
متن کاملOutflow Feedback Regulated Massive Star Formation in Parsec-Scale Cluster Forming Clumps
We investigate massive star formation in turbulent, magnetized, parsec-scale clumps of molecular clouds including protostellar outflow feedback using three dimensional numerical simulations of effective resolution 2048. The calculations are carried out using a block structured adaptive mesh refinement code that solves the ideal MHD equations including self-gravity and implements accreting sink ...
