Investigating Changing-Look Active Galactic Nuclei with Long-term Optical and X-Ray Observations
A. Jana, C. Ricci, M. J. Temple +7
Changing-look active galactic nuclei (CLAGNs) show the appearance and disappearance of broad emission lines in their UV/optical spectra on timescales of months to decades. Here, we…
HYPERION: broad-band X-ray-to-near-infrared emission of Quasars in the first billion years of the Universe
I. Saccheo, A. Bongiorno, E. Piconcelli +41
We aim at characterizing the X-ray-to-optical/near-infrared broad-band emission of luminous QSOs in the first Gyr of cosmic evolution to understand whether they exhibit differences…
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…
BASS XLI: the correlation between Mid-infrared emission lines and Active Galactic Nuclei emission
M. Bierschenk, C. Ricci, M. J. Temple +22
We analyze the Spitzer spectra of 140 active galactic nuclei (AGN) detected in the hard X-rays (14-195 keV) by the Burst Alert Telescope (BAT) on board Swift. This sample allows us…
BASS. XLIII: Optical, UV, and X-ray emission properties of unobscured Swift/BAT active galactic nuclei
Kriti K. Gupta, Claudio Ricci, Matthew J. Temple +19
We present one of the largest multiwavelength studies of simultaneous optical-to-X-ray spectral energy distributions (SEDs) of unobscured active galactic nuclei (AGN) in the local…
The SDSS-V Black Hole Mapper Reverberation Mapping Project: A Kinematically Variable Broad-Line Region and Consequences for Masses of Luminous Quasars
Logan B. Fries, Jonathan R. Trump, Keith Horne +27
We present a velocity-resolved reverberation mapping analysis of the hypervariable quasar RM160 (SDSS J141041.25+531849.0) at z = 0.359 with 153 spectroscopic epochs of data repres…
