MHD simulations of the collapsar model for GRBs
D. Proga, A. I. MacFadyen, P. J. Armitage +1
We present results from axisymmetric, time-dependent magnetohydrodynamic (MHD) simulations of the collapsar model for gamma-ray bursts. Our main conclusion is that, within the coll…
X-ray Pulsars in the Small Magellanic Cloud
W. A. Majid, R. C. Lamb, D. J. Macomb
XMM-Newton archival data for the Small Magellanic Cloud have been examined for the presence of previously undetected X-ray pulsars. One such pulsar, with a period of 202 s, is dete…
Modelling of the continuum emission from Class 0 sources
M. Rengel, D. Froebrich, S. Wolf +1
Class 0 sources are objects representing the earliest phase of the protostellar evolution. Since they are highly obscured by an extended dusty envelope, these objects emit mainly i…
The impact of shocks on the chemistry of molecular clouds: high resolution images of chemical differentiation along the NGC1333-IRAS2A outflow
J. K. Jorgensen, M. R. Hogerheijde, G. A. Blake +3
This paper presents a detailed study of the chemistry in the outflow associated with the low-mass protostar NGC1333-IRAS2A down to 3" (650 AU) scales. Millimeter-wavelength apertur…
Near-Infrared Colors of Submillimeter-Selected Galaxies
D. T. Frayer, N. A. Reddy, L. Armus +3
We report on deep near-infrared (NIR) observations of submillimeter-selected galaxies (SMGs) with the Near Infrared Camera (NIRC) on the Keck I telescope. We have identified K-band…
The structure of the NGC1333-IRAS2 protostellar system on 500 AU scales: an infalling envelope, a circumstellar disk, multiple outflows, and chemistry
J. K. Jorgensen, M. R. Hogerheijde, E. F. van Dishoeck +2
This paper investigates small-scale structures of dense gas and dust around the low-mass protostellar binary NGC1333-IRAS2 using millimeter-wavelength aperture-synthesis observatio…
