SIROCCO: A Publicly Available Monte Carlo Ionization and Radiative Transfer Code for Astrophysical Outflows

James H. Matthews, Knox S. Long, Christian Knigge +8

Outflows are critical components of many astrophysical systems, including accreting compact binaries and active galactic nuclei (AGN). These outflows can significantly affect a sys…

A multi-dimensional view of a unified model for TDEs

Edward J. Parkinson, Christian Knigge, Lixin Dai +3

Tidal disruption events (TDEs) can generate non-spherical, relativistic and optically thick outflows. Simulations show that the radiation we observe is reprocessed by these outflow…

Optical line spectra of tidal disruption events from reprocessing in optically thick outflows

Edward J. Parkinson, Christian Knigge, James H. Matthews +4

A significant number of tidal disruption events (TDEs) radiate primarily at optical and ultraviolet (UV) wavelengths, with only weak soft X-ray components. One model for this optic…

Accretion Disc Winds in Tidal Disruption Events: Ultraviolet Spectral Lines as Orientation Indicators

Edward J. Parkinson, Christian Knigge, Knox S. Long +4

Some tidal disruption events (TDEs) exhibit blueshifted broad absorption lines (BALs) in their rest-frame ultraviolet (UV) spectra, while others display broad emission lines (BELs)…

Thermal and radiation driving can produce observable disk winds in hard-state X-ray binaries

Nick Higginbottom, Christian Knigge, Stuart A. Sim +5

X-ray signatures of outflowing gas have been detected in several accreting black-hole binaries, always in the soft state. A key question raised by these observations is whether the…

Stratified disc wind models for the AGN broad-line region: ultraviolet, optical and X-ray properties

James H. Matthews, Christian Knigge, Nick Higginbottom +5

The origin, geometry and kinematics of the broad line region (BLR) gas in quasars and active galactic nuclei (AGN) are uncertain. We demonstrate that clumpy biconical disc winds il…
