On the diversity and complexity of absorption line profiles produced by outflows in Active Galactic Nuclei
Margherita Giustini, Daniel Proga
Understanding the origin of AGN absorption line profiles and their diversity could help to explain the physical structure of the accretion flow, and also to assess the impact of ac…
Parker Winds Revisited: An Extension to Disc Winds
Timothy R. Waters, Daniel Proga
A simple 1D dynamical model of thermally driven disc winds is proposed, based on the results of recent, 2.5D axi-symmetric simulations. Our formulation of the disc wind problem is…
Synthetic X-ray spectra for simulations of the dynamics of an accretion flow irradiated by a quasar
S. A. Sim, D. Proga, R. Kurosawa +3
Ultraviolet and X-ray observations show evidence of outflowing gas around many active galactic nuclei. Some of these outflows may be driven off gas infalling towards the central bl…
Regulation of Black Hole Winds and Jets Across the Mass Scale
Ashley L. King, Jon M. Miller, John Raymond +7
We present a study of the mechanical power generated by both winds and jets across the black hole mass scale. We begin with the study of ionized X-ray winds and present a uniform a…
On time variability and other complications in studying the UV broad absorption lines of quasars: results from numerical simulations of radiation driven disk winds
Daniel Proga, Paola Rodríguez Hidalgo, Fred Hamann
We review the main results from axisymmetric, time-dependent hydrodynamical simulations of radiation driven disk winds in AGN. We illustrate the capability of such simulations to p…
Parker Winds Revisited: An Extension to Disk Winds
Tim Waters, Daniel Proga
A simple, one-dimensional dynamical model of thermally driven disk winds, one in the spirit of the original Parker (1958) model, is presented. We consider two different axi-symmetr…
