Effects of an Immortal Stellar Population in AGN Disks
Adam S. Jermyn, Alexander J. Dittmann, B. McKernan +2
Stars are likely embedded in the gas disks of Active Galactic Nuclei (AGN). Theoretical models predict that in the inner regions of the disk these stars accrete rapidly, with fresh…
Predicting the spectrum of UGC 2885, Rubin's Galaxy with machine learning
Benne W. Holwerda, John F. Wu, William C. Keel +10
Wu & Peek (2020) predict SDSS-quality spectra based on Pan-STARRS broad-band \textit{grizy} images using machine learning (ML). In this letter, we test their prediction for a uniqu…
Aligning Nuclear Cluster Orbits with an Active Galactic Nucleus Accretion Disk
Gaia Fabj, Syeda S. Nasim, Freddy Caban +3
Active galactic nuclei (AGN) are powered by the accretion of disks of gas onto supermassive black holes (SMBHs). Stars and stellar remnants orbiting the SMBH in the nuclear star cl…
The first high-redshift changing-look quasars
Nicholas P. Ross, Matthew J. Graham, Giorgio Calderone +3
We report on three redshift quasars with dramatic changes in their C IV emission lines, the first sample of changing-look quasars (CLQs) at high redshift. This is also the fi…
The evolution of kicked stellar-mass black holes in star cluster environments II. Rotating star clusters
Jeremy J. Webb, Nathan W. C. Leigh, Roberto Serrano +5
In this paper, we continue our study on the evolution of black holes (BHs) that receive velocity kicks at the origin of their host star cluster potential. We now focus on BHs in ro…
Understanding extreme quasar optical variability with CRTS: II. Changing-state quasars
Matthew J. Graham, Nicholas P. Ross, Daniel Stern +8
We present the results of a systematic search for quasars in the Catalina Real-time Transient Survey exhibiting both strong photometric and spectroscopic variability over a decadal…
