Understanding the Broad-line Region of Active Galactic Nuclei with Photoionization. II. Slim disks, Self-shadowing, and BLR sizes
Qiaoya Wu, Yue Shen, Chris Done +2
Reverberation-mapping (RM) measurements have revealed that high-accretion-rate active galactic nuclei (AGNs) systematically lie below the canonical broad-line region (BLR) radius -…
Directly tracking the re-brightening of a supermassive black hole accretion disk
R. Middei, E. Nardini, C. Done +12
Accretion onto supermassive black holes powers the most luminous persistent sources in the Universe, the so-called active galactic nuclei, whose emission is characterized by two di…
Unveiling BLR Structure in AGN with High Resolution X-Ray Spectra: An Analytic Approach to Wind Emission Line Profiles
Scott Hagen, Chris Done, Gabriele A. Matzeu +1
XRISM has provided an unprecedented view of the emission and absorption lines in the X-ray. Notably, early results showed significant complexity to the Fe-K line profile in AGN,…
Disk-jet-wind coupling from stellar mass to supermassive black holes
Chris Done
Black holes are the simplest possible objects, characterised by only mass and spin. We see them via accretion, so there is one more fundamental parameter which is the mass accretio…
Accretion disc winds in X-ray binaries
Teo Muñoz-Darias, María Díaz Trigo, Chris Done +2
Despite early theoretical expectations that large-scale, massive outflows would be triggered by accretion onto black holes and neutron stars, their presence was not firmly establis…
First Light and Reionization Epoch Simulations (FLARES) -- XVIII: the ionising emissivities and hydrogen recombination line properties of early AGN
Stephen M. Wilkins, Aswin P. Vijayan, Scott Hagen +10
One of the most remarkable results from the \emph{James Webb Space Telescope} has been the discovery of a large population of compact sources exhibiting strong broad H emission,…
Disk-jet coupling across the spectral transition in supermassive black holes
Jia-Lai Kang, Chris Done, Scott Hagen +5
Accretion flows in both stellar and supermassive black holes show a distinct spectral transition. This is seen directly in binaries and changing look AGN, and also in a recent samp…
Systematic collapse of the accretion disc in AGN confirmed by UV photometry and broad line spectra
Jia-Lai Kang, Chris Done, Scott Hagen +4
A recent study on the spectral energy distribution (SED) of AGN combined unobscured X-ray sources from the eROSITA eFEDS Survey with high quality optical imaging from Subaru's Hype…
Common origin for black holes in both high mass X-ray binaries and gravitational-wave sources
K. Belczynski, C. Done, S. Hagen +2
Black-hole (BH) high-mass X-ray binary (HMXB) systems are likely to be the progenitors of BH-BH mergers detected by LIGO/Virgo/KAGRA (LVK). Yet merging BHs reach higher masses ($\s…
The impact of thermal winds on the outburst lightcurves of black hole X-ray binaries
G. Dubus, C. Done, B. E. Tetarenko +1
The observed signatures of winds from X-ray binaries are broadly consistent with thermal winds, driven by X-ray irradiation of the outer accretion disc. Thermal winds produce mass…
