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…
Axisymmetric MHD simulations of the collapsar model for gamma-ray bursts
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. We begin the simulations after the 1.7 MSUN…
On the relative frequencies of core-collapse supernovae sub-types: the role of progenitor metallicity
Nikos Prantzos, Samuel Boissier
We show that the observed ratio of the subtypes Ib,c and II core-collapse supernovae depends on the metallicity of the host galaxy, as expected on theoretical grounds. However, the…
Early Preheating and Galaxy Formation
A. J. Benson, P. Madau
Winds from pregalactic starbursts and 'miniquasars' may pollute the IGM with metals and raise its temperature to a high adiabat, and so inhibit the formation of early galaxies. We…
Follow-up of the 9C survey: Initial results
R. C. Bolton, G. Cotter, T. J. Pearson +4
We present initial results from a follow-up of the 9C survey, complete to 25 mJy at 15 GHz, designed to assemble and investigate a sample of young radiosources. We have made radio…
