SHELLQs-JWST perspective on the intrinsic mass relation between supermassive black holes and their host galaxies at z > 6
John Silverman, Junyao Li, Xuheng Ding +36
The relation between the masses of supermassive black holes (SMBHs) and their host galaxies encodes information on their mode of growth, especially at the earliest epochs. The Jame…
Flares in the Changing Look AGN Mrk 590. II: Deep X-ray observations reveal a Comptonizing inner accretion flow
Daniel Lawther, Marianne Vestergaard, Sandra Raimundo +2
Mrk 590 is a Changing Look AGN currently in an unusual repeat X-ray and UV flaring state. Here, we report on deep X-ray observations with XMM-Newton, NuSTAR, and NICER, obtained at…
Direct Evidence for AGN Feedback from Fast Molecular Outflows in Reionization-Era Quasars
Justin S. Spilker, Jaclyn B. Champagne, Xiaohui Fan +4
Galactic outflows driven by rapidly-accreting quasars at high redshift are widely expected to play a key role in the short- and long-term future evolution of their host galaxies. U…
Time Evolution of Mg II in SDSS J2320+0024: Implications for a Subparsec Binary Supermassive Black Hole System
Marta FatoviÄ, Dragana IliÄ, Andjelka B. KovaÄeviÄ +8
Here we present results from our spectroscopic follow-up of SDSS J2320+0024, a candidate binary supermassive black hole (SMBH) with a suspected sub-pc separation, identified by a 2…
Discovery of a Unique Close Quasar-DSFG Pair Linked by a [C II] Bridge at
Yongda Zhu, Tom J. L. C. Bakx, Ryota Ikeda +11
We report the discovery of a unique quasar-dusty star-forming galaxy (DSFG) system at , consisting of the bright quasar J1133+1603 () and its compact…
Lack of Rest-frame UV Variability in Little Red Dots Based on HST and JWST Observations
Wei Leong Tee, Xiaohui Fan, Feige Wang +1
Variability is a fundamental signature for active galactic nuclei (AGN) activity, and serve as an unbiased indicator for rapid instability happened near the center supermassive bla…
