A UV to X-Ray View of Soft Excess in Type 1 Active Galactic Nuclei. II. Broadband Correlations
Shi-Jiang Chen, Jun-Xian Wang, Jia-Lai Kang +5
The physical origin of soft X-ray excess (SE) is a long lasting question, with two prevailing theories -- ``warm corona'' and ``ionized reflection'' -- dominating the discussion. I…
The Average Soft X-ray Spectra of eROSITA Active Galactic Nuclei
Shi-Jiang Chen, Johannes Buchner, Teng Liu +16
Context. AGNs are strong X-ray emitters shaped by disk-corona interactions. The soft excess (0.5-2.0 keV) reveals key information about the "warm corona" bridging the disk and hot…
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…
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…
XMM Observations of the Seyfert 2 Galaxy NGC 7590: the Nature of X-ray Absorption
X. W. Shu, T. Liu, J. X. Wang
We present the analysis of three XMM observations of the Seyfert 2 galaxy NGC 7590. The source was found to have no X-ray absorption in the low spatial resolution ASCA data. The XM…
