Massive black hole formation in dense stellar environments: Enhanced X-ray detection rates in high velocity dispersion nuclear star clusters
Vivienne F. Baldassare, Nicholas C. Stone, Adi Foord +2
We analyze Chandra X-ray Observatory imaging of 108 galaxies hosting nuclear star clusters (NSCs) to search for signatures of massive black holes (BHs). NSCs are extremely dense st…
Investigating the Accretion Nature of Binary Supermassive Black Hole Candidate SDSS J025214.67-002813.7
Adi Foord, Xin Liu, Kayhan Gültekin +3
We present results on a multi-wavelength analysis of SDSS J025214.67-002813.7, a system which has been previously classified as a binary AGN candidate based on periodic signals det…
AGN Triality of Triple Mergers: Multi-wavelength Classifications
Adi Foord, Kayhan Gultekin, Jessie C. Runnoe +1
We present results from a multi-wavelength analysis searching for multiple AGN systems in nearby (z<0.077) triple galaxy mergers. Combining archival Chandra, SDSS, WISE, and VLA ob…
AGN Triality of Triple Mergers: Detection of Faint X-ray Point Sources
Adi Foord, Kayhan Gultekin, Jessie C. Runnoe +1
We present results from our X-ray analysis of the first systematic search for triple AGN in nearby (z<0.077) triple galaxy mergers. We analyze archival Chandra observations of 7 tr…
Extended X-ray emission from the z=4.26 radio galaxy 4C 63.20
Kate Napier, Adi Foord, Elena Gallo +5
We report on deep Chandra X-ray Telescope imaging observations of 4C 63.20, one of the few known radio galaxies at z>3.5. The X-ray counterpart is resolved into a core plus two off…
A Second Look at 12 Candidate Dual AGNs using
Adi Foord, Kayhan Gültekin, Rebecca Nevin +5
We present an analysis of 12 optically selected dual AGN candidates at . Each candidate was originally identified via double-peaked [O III] 5007 emission lines, and ha…
A Bayesian Analysis of SDSS J0914+0853, a Low-Mass Dual AGN Candidate
Adi Foord, Kayhan Gultekin, Mark T. Reynolds +6
We present the first results from BAYMAX (Bayesian AnalYsis of Multiple AGN in X-rays), a tool that uses a Bayesian framework to quantitatively evaluate whether a given Chandra obs…
A Multi-wavelength Analysis of Binary-AGN Candidate PSO J334.2028+01.4075
Adi Foord, Kayhan Gultekin, Mark Reynolds +4
We present analysis of the first Chandra observation of PSO J334.2028+01.4075 (PSO J334), targeted as a binary-AGN candidate based on periodic variations of the optical flux. With…
AGN Activity in Nucleated Galaxies as Measured by Chandra
Adi Foord, Elena Gallo, Edmund Hodges-Kluck +4
Motivated by theoretical expectations that Nuclear Star Clusters (NSCs) in galactic centers may provide a favorable environment for super-massive black holes to form and/or efficie…
