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…

The "SPectrogram Analysis and Cataloguing Environment" (SPACE) Labelling Tool

C. K. Louis, C. M. Jackman, S. W. Mangham +6

The SPectrogram Analysis and Cataloguing Environment (SPACE) tool is an interactive python tool designed to label radio emission features of interest in a time-frequency map (calle…

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…

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…

Do Reverberation Mapping Analyses Provide an Accurate Picture of the Broad Line Region?

S. W. Mangham, C. Knigge, P. Williams +6

Reverberation mapping (RM) is a powerful approach for determining the nature of the broad-line region (BLR) in active galactic nuclei. However, inferring physical BLR properties fr…

The reverberation signatures of rotating disc winds in active galactic nuclei

S. W. Mangham, C. Knigge, J. H. Matthews +3

The broad emission lines (BELs) in active galactic nuclei (AGN) respond to ionizing continuum variations. The time and velocity dependence of their response depends on the structur…
