Dynamics of Line-driven Disk Winds in Active Galactic Nuclei

TL;DR: In this paper, the authors present the results of axisymmetric time-dependent hydrodynamic calculations of line-driven winds from accretion disks in active galactic nuclei (AGNs).

The Hot and Energetic Universe: A White Paper presenting the science theme motivating the Athena+ mission

Kirpal Nandra, +239 more
TL;DR: The Advanced Telescope for High Energy Astrophysics (Athena+) mission as discussed by the authors provides the necessary performance (e.g., angular resolution, spectral resolution, survey grasp) to address these questions and revolutionize our understanding of the Hot and Energetic Universe.
Journal ArticleDOI

Dynamics of line-driven disk winds in active galactic nuclei. ii. effects of disk radiation

TL;DR: In this article, a radiation-driven disk wind model for mass outflows from active galactic nuclei (AGNs) was proposed and axisymmetric time-dependent hydrodynamic calculations were performed using the same computational technique as Proga, Stone, and Kallman.
Journal ArticleDOI

Discerning the physical origins of cosmological Gamma-ray bursts based on multiple observational criteria: the cases of z=6.7 GRB 080913, z=8.3 GRB 090423, and some short/hard GRBs

TL;DR: In this article, the authors perform a more thorough investigation on two physically distinct types (Type I/II) of cosmological GRBs and their observational characteristics, and they suggest that GRB 080913 and GRB 090423 are more likely Type II events.
