A Mapping Survey of Dense Clumps Associated with Embedded Clusters : Evolutionary Stages of Cluster-Forming Clumps
We have carried out a survey of the dense clumps associated with 14 embedded clusters in the CO (J=1–0) line emission with the Nobeyama 45m telescope in order to understand the formation and evolution of stellar clusters in dense clumps of molecular clouds. We have selected these clusters at distances from 0.3 to 2.1 kpc and have mapped about 6 × 6 to 10 × 10 regions (corresponding to 3.8 pc × ...
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 ...
متن کاملThe Spiderweb Galaxy: a Forming Massive Cluster Galaxy
We present a deep image of the radio galaxy MRC 1138 262 taken with the Hubble Space Telescope (HST) at a redshift of . The galaxy is known to have properties of a cD galaxy progenitor and be surrounded z p 2.2 by a 3 Mpc–sized structure, identified with a protocluster. The morphology shown on the new deep HST ACS image is reminiscent of a spider’s web. More than 10 individual clumpy features a...

15 صفحه اولGiant clumps in the FIRE simulations: a case study of a massive high-redshift galaxy
The morphology of massive star-forming galaxies at high redshift is often dominated by giant clumps of mass ∼ 10 − 10 M and size ∼ 100 − 1000 pc. Previous studies have proposed that giant clumps might have an important role in the evolution of their host galaxy, particularly in building the central bulge. However, this depends on whether clumps live long enough to migrate from their original lo...
