Evidence for Inflow in High-Mass Star-Forming Clumps
Evidence for Inflow in High-Mass Star-Forming Clumps
2011/10/17
We analyze the HCO+ 3-2 and H13CO+ 3-2 line profiles of 27 high-mass star-forming regions to identify asymmetries that are suggestive of mass inflow. Three quantitative measures of line asymmetry are ...
Dense DM clumps seeded by cosmic string loops and DM annihilation
dark matter cosmic string cosmology
2011/10/9
The annihilation of the dark matter in clumps around cosmic string loops is studied. These clumps form at the radiation dominated stage and may have densities \gg\rho_{eq}. We conclude that 100 GeV ne...
We study the mass-density relationship n m^x in molecular cloud clumps, considering various relations between the gravitational, kinetic, internal and magnetic energy. Clumps are described statistical...
Short-lived star-forming giant clumps in cosmological simulations of z~2 disks
galaxies evolution— galaxies formation— galaxies high-redshift—galaxies structure
2010/11/9
Many observed massive star-forming z ≈ 2 galaxies are large disks that exhibit irregular morphologies, with ≈ 1 kpc, ≈ 108-10M⊙ clumps. We present high-resolution cosmological SPH simulations that zoo...
