The MHD collapsar model for GRBs: an inflow produces an outflow
Daniel Proga
We present our recent results from numerical simulations of a magnetized flow in the vicinity of a black hole in the context of the collapsar model for GRBs. The simulations show t…
On how much X-ray and UV radiation processes are coupled in accretion disks: AGN case
Daniel Proga
Within the standard accretion disk theory for active galactic nuclei (AGN), the observed X-rays are often modeled by Compton up-scattering of ultraviolet (UV) disk photons inside a…
On MHD jet production in the collapsing and rotating envelope
Daniel Proga
We present results from axisymmetric, time-dependent hydrodynamical (HD) and magnetohydrodynamical (MHD) simulations of a gaseous envelope collapsing onto a black hole (BH). We con…
X-ray/UV Observing Campaign on the Mrk 279 AGN Outflow: A Global Fitting Analysis of the UV Absorption
Jack R. Gabel, Nahum Arav, Jelle S. Kaastra +12
We present an analysis of the intrinsic UV absorption in the Seyfert 1 galaxy Mrk 279 based on simultaneous long observations with the Hubble Space Telescope (41 ks) and the Far Ul…
