The study of ultraluminous X-ray sources (ULXs) has changed dramatically over the last
decade. In this review we first describe the most important observations of ULXs in various …

Abstract Contents:(1) Introduction.(2) Inferences insensitive to detailed model: Some fiducial
numbers. Processes in ultrahot thermal plasma. Cyclotron/synchrotron and inverse Compton …

We present a review of the influence of cosmic repulsion and external magnetic fields on
accretion disks rotating around rotating black holes and on jets associated with these …

Accretion discs in astrophysics ADS Classic is now deprecated. It will be completely retired in
October 2019. This page will automatically redirect to the new ADS interface at that point …

Powerful extragalactic radio sources comprise two extended regions containing magnetic
field and synchrotron-emitting relativistic electrons, each linked by a jet to a central compact …

Abstract Models of thick accretion disks surrounding black holes are developed which have
a consistent time-averaged stationary behavior, and implications of these models for disk …

We describe a conservative, shock-capturing scheme for evolving the equations of general
relativistic magnetohydrodynamics. The fluxes are calculated using the Harten, Lax, & van …

While apparently supplying tremendous power to their extended radio-emitting regions, the
nuclei of most radio galaxies emit little detectable radiation. It is proposed that at the centre …

Black hole (BH) accretion flows and jets are dynamic hot relativistic magnetized plasma
flows whose radiative opacity can significantly affect flow structure and behaviour. We …

The M87 jet is extensively examined by utilizing general relativistic magnetohydrodynamic
(GRMHD) simulations, as well as the steady axisymmetric force-free electrodynamic (FFE) …
