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…
An Eddington Limited Accretion Disk Wind in the narrow line Seyfert 1, PG 1448+273
J. N. Reeves, V. Braito, A. Luminari +5
PG 1448+273 is a luminous, nearby (), narrow line Seyfert 1 galaxy, which likely accretes close to the Eddington limit. Previous X-ray observations of PG 1448 with XMM-Ne…
Revealing the burning and soft heart of the bright bare AGN ESO 141-G55: X-ray broadband and SED analysis
Delphine Porquet, James N. Reeves, Scott Hagen +4
[Abridged] ESO 141-G55 is a nearby X-ray bright BLS1, which has been classified as a bare AGN due to the lack of warm absorption along its line-of-sight, providing an unhampered vi…
Systematic Collapse of the Accretion Disc Across the Supermassive Black Hole Population
Scott Hagen, Chris Done, John D. Silverman +7
The structure of the accretion flow onto supermassive black holes (SMBH) is not well understood. Standard disc models match to zeroth order in predicting substantial energy dissipa…
The Peculiar Bursting Nature of CP Pup
M. Veresvarska, S. Scaringi, S. Hagen +5
The classical nova CP Puppis has been observed to have particularly puzzling and peculiar properties. In particular, this classical nova displays occasional bursts in its long-term…
What Drives the Variability in AGN? Explaining the UV-Xray Disconnect Through Propagating Fluctuations
Scott Hagen, Chris Done, Rick Edelson
Intensive broadband reverberation mapping campaigns have shown that AGN variability is significantly more complex than expected from disc reverberation of the variable X-ray illumi…
