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…
Crimson Behemoth: a Massive Clumpy Structure Hosting a Dusty AGN at
Takumi S. Tanaka, John D. Silverman, Yurina Nakazato +40
The current paradigm for the co-evolution of galaxies and their supermassive black holes postulates that dust-obscured active galactic nuclei (AGNs) represent a transitional phase…
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…
A Two-zone Accretion Disk in the Changing-look Active Galactic Nucleus 1ES 1927+654: Physical Implications for Tidal Disruption Events and Super-Eddington Accretion
Ruancun Li, Luis C. Ho, Claudio Ricci +1
The properties of slim accretion disks, while crucial for our understanding of black hole growth, have yet to be studied extensively observationally. We analyze the multi-epoch bro…
The Interplay between the Disk and Corona of the Changing-look Active Galactic Nucleus 1ES 1927+654
Ruancun Li, Claudio Ricci, Luis C. Ho +4
Time-domain studies of active galactic nuclei (AGNs) offer a powerful tool for understanding black hole accretion physics. Prior to the optical outburst on 23 December 2017, 1ES 19…
A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6
Masafusa Onoue, Xuheng Ding, John D. Silverman +45
Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): Broad-line AGN at revealed by JWST/NIRCam WFSS
Xiaojing Lin, Feige Wang, Xiaohui Fan +33
Low-luminosity AGNs with low-mass black holes (BHs) in the early universe are fundamental to understanding the BH growth and their co-evolution with the host galaxies. Utilizing JW…
COSMOS-Web: The over-abundance and physical nature of "little red dots"--Implications for early galaxy and SMBH assembly
Hollis B. Akins, Caitlin M. Casey, Erini Lambrides +38
JWST has revealed a population of compact and extremely red galaxies at , which likely host active galactic nuclei (AGN). We present a sample of 434 ``little red dots'' (LRDs)…
A quasar-galaxy merger at : rapid host growth via accretion of two massive satellite galaxies

We present ALMA band-7 observations of J2057-0030, a multi-component merger system at 4.68 spanning at least 50 kpc in size, using the [CII] 157.74 m line and unde…
Joint ALMA/X-ray monitoring of the radio-quiet type 1 AGN IC 4329A
E. Shablovinskaya, C. Ricci, C-S. Chang +20
The origin of a compact millimeter (mm, 100-250 GHz) emission in radio-quiet active galactic nuclei (RQ AGN) remains debated. Recent studies propose a connection with self-absorbed…
