Gas Accretion by Globular Clusters and Nucleated Dwarf Galaxies and the Formation of the Arches and Quintuplet Clusters
Douglas N. C. Lin, Stephen D. Murray
We consider here the collective accretion of gas by globular clusters and dwarf galaxies moving through the interstellar medium. In the limit of high velocity and/or sound speed of…
Energy Dissipation in Multi-Phase Infalling Clouds in Galaxy Halos
Stephen D. Murray, Douglas N. C. Lin
During the formation of large galaxies, thermal instability leads to the formation of a population of cool fragments embedded within a background of tenuous hot gas. The hot gas at…
Jet-Induced Star Formation: Good News From Big Bad Black Holes
Wil van Breugel, Chris Fragile, Stephen Croft +3
We discuss obbservations and numerical simulations which show that radiative shocks in jet-cloud collisions can trigger the collapse of intergalactic clouds and subsequent star for…
Jet-Induced Star Formation
Wil van Breugel, Chris Fragile, Peter Anninos +1
Jets from radio galaxies can have dramatic effects on the medium through which they propagate. We review observational evidence for jet-induced star formation in low ('FR-I') and h…
Star Formation and Feedback in Dwarf Galaxies
Shawfeng Dong, D. N. C. Lin, S. D. Murray
We examine the star formation history and stellar feedback effects of dwarf galaxies under the influence of extragalactic ultraviolet radiation. We consider the dynamical evolution…
Radiative Shock-Induced Collapse of Intergalactic Clouds
P. Chris Fragile, Stephen D. Murray, Peter Anninos +1
Accumulating observational evidence for a number of radio galaxies suggests an association between their jets and regions of active star formation. The standard picture is that sho…
Roche Lobe Overflow from Dwarf Stellar Systems
Stephen D. Murray, Shawfeng Dong, Douglas N. C. Lin
We use both analytical analyses and numerical simulations to examine the evolution of residual gas within tidally-limited dwarf galaxies and globular clusters. If the gas sound spe…
COSMOS: A Radiation-Chemo-Hydrodynamics Code for Astrophysical Problems
Peter Anninos, P. Chris Fragile, Stephen D. Murray
We have developed a new massively-parallel radiation-hydrodynamics code (Cosmos) for Newtonian and relativistic astrophysical problems that also includes radiative cooling, self-gr…
Supernova Enrichment of Dwarf Spheroidal Galaxies
P. Chris Fragile, Stephen D. Murray, Peter Anninos +1
(Abridged) Many dwarf galaxies exhibit sub-Solar metallicities, with some star-to-star variation, despite often containing multiple generations of stars. The total metal content in…
Accretion Disk Coronae in High Luminosity Systems
Stephen D. Murray, John I. Castor, Richard I. Klein +1
We present the results of self-consistent models of Compton-heated accretion disk coronae. The models are calculated using a new method for computing monochromatic radiative transf…
N-Body Simulations of Star-Disc Captures in Globular Clusters
S. D. Murray, C. J. Clarke
The presence of protostellar disks can greatly increase the dissipation during close stellar encounters, leading to the formation of a significant population of binaries during the…
