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…
Mass Outflows from Accretion Disks: Old and New Challenges
D. Proga
We summarize recent developments in modeling of mass outflows from accretion disks in AGN. We illustrate how the hydrodynamical and magnetohydrodynamical wind structures revealed i…
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…
Accretion of low angular momentum material onto black holes: 2D magnetohydrodynamical case
D. Proga, M. C. Begelman
We report on the second phase of our study of slightly rotating accretion flows onto black holes. We consider magnetohydrodynamical (MHD) accretion flows with a spherically symmetr…
