Investigating the Multiwavelength Emission of Binary SMBH Candidate SDSS J095036.75+512838.1
Cassandra Daniele, Adi Foord, Jessie Runnoe +2
We present results from a multiwavelength study of the binary AGN candidate SDSS J095036.75+512838.1, which was identified as a candidate binary SMBH system due to its significant…
Simulating Disky Broad Line Region Reverberation
Mary Ogborn, Michael Eracleous, Jessie C. Runnoe +3
Variability studies of the broad emission lines of Active Galactic Nuclei (AGNs) and quasars show stochastic radial velocity variations (i.e., fluctuations in the centroid of the l…
Spectroscopic Variability of the Broad H Emission Line in Sloan Digital Sky Survey Quasars
Collin M. Dabbieri, Jessie C. Runnoe, Michael Eracleous +3
We present a catalog of broad H variability properties for all spectra of quasars with and at least two observations included in the Sloan Digital Sky Survey (SDSS) Dat…
The Tantalizing Case of the Quasar J0950+5128 -- I. Presentation of the Data and Detailed Exploration of the Binary Supermassive Black Hole Scenario
Niana N. Mohammed, Jessie C. Runnoe, Michael Eracleous +8
Spectroscopic observations of the quasar J09505128 spanning 22 years reveal monotonic radial velocity variations in its broad H emission line. Moreover, the line profile bec…
