Can AGN activity be enhanced by ram pressure stripping? -- X-ray perspective
Juhi Tiwari, Ming Sun, Rongxin Luo +3
Ram pressure stripping (RPS) is an important process that plays a significant role in shaping the evolution of cluster galaxies and their surrounding environment. Despite its recog…
The Most Obscured AGNs in the XMM-SERVS Fields
Wei Yan, W. N. Brandt, Fan Zou +9
We perform X-ray spectral analyses to derive characteristics (e.g., column density, X-ray luminosity) of 10,200 active galactic nuclei (AGNs) in the XMM-Spitzer Extragalac…
NuSTAR observations of a heavily X-ray obscured AGN in the dwarf galaxy J144013+024744
Shrey. Ansh, Chien-Ting J. Chen, W. N. Brandt +10
We present a multi-wavelength analysis of the dwarf Seyfert-2 galaxy J, a candidate obscured active galactic nucleus (AGN) thought to be powered by an intermediate-m…
Spectral Energy Distributions in Three Deep-Drilling Fields of the Vera C. Rubin Observatory Legacy Survey of Space and Time: Source Classification and Galaxy Properties
Fan Zou, W. N. Brandt, Chien-Ting Chen +9
W-CDF-S, ELAIS-S1, and XMM-LSS will be three Deep-Drilling Fields (DDFs) of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), but their extensive multi-waveleng…
Consistent analysis of the AGN LF in X-ray and MIR in the XMM-LSS field
Jack Runburg, Duncan Farrah, Anna Sajina +9
The luminosity function (LF) of active galactic nuclei (AGN) probes the history of supermassive black hole assembly and growth across cosmic time. To mitigate selection biases, we…
The XMM-SERVS survey: XMM-Newton point-source catalogs for the W-CDF-S and ELAIS-S1 fields
Q. Ni, W. N. Brandt, C. -T. Chen +30
We present the X-ray point-source catalogs in two of the XMM-Spitzer Extragalactic Representative Volume Survey (XMM-SERVS) fields, W-CDF-S (4.6 deg) and ELAIS-S1 (3.2 deg)…
Chandra Observations of Excess Fe K Line Emission in Galaxies with High Star Formation Rates: X-ray Reflection on Galaxy Scales?
Wei Yan, Ryan C. Hickox, Chien-Ting J. Chen +4
In active galactic nuclei (AGN), fluorescent Fe K (iron) line emission is generally interpreted as originating from obscuring material around a supermassive black hole (SMBH) on…
Observational Evidence for Enhanced Black Hole Accretion in Giant Elliptical Galaxies
Michael McDonald, Brian R. McNamara, Michael S. Calzadilla +5
We present a study of the relationship between black hole accretion rate (BHAR) and star formation rate (SFR) in a sample of giant elliptical galaxies. These galaxies, which live a…
A Large Population of Luminous Active Galactic Nuclei Lacking X-ray Detections: Evidence for Heavy Obscuration?
Christopher M. Carroll, Ryan C. Hickox, Alberto Masini +5
We present a large sample of infrared-luminous candidate active galactic nuclei (AGNs) that lack X-ray detections in Chandra, XMM-Newton, and NuSTAR fields. We selected all optical…
Piercing through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields. II. Are Highly Obscured AGNs the Missing Link in the Merger-Triggered AGN-Galaxy Coevolution Models?
Junyao Li, Yongquan Xue, Mouyuan Sun +12
By using a large highly obscured () AGN sample (294 sources at ) selected from detailed X-ray spectral analyses in the deepest Chandra…
Piercing Through Highly Obscured and Compton-thick AGNs in the Chandra Deep Fields: I. X-ray Spectral and Long-term Variability Analyses
Junyao Li, Yongquan Xue, Mouyuan Sun +13
We present a detailed X-ray spectral analysis of 1152 AGNs selected in the Chandra Deep Fields (CDFs), in order to identify highly obscured AGNs (…
Investigating the Covering Fraction Distribution of Swift/BAT AGN with X-ray and IR Observations
Lauranne Lanz, Ryan C. Hickox, Mislav Baloković +12
We present an analysis of a sample of 69 local obscured Swift/Burst Alert Telescope active galactic nuclei (AGNs) with X-ray spectra from NuSTAR and infrared (IR) spectral energy d…
A Tale of Two Narrow-Line Regions: Ionization, Kinematics, and Spectral Energy Distributions for a Local Pair of Merging Obscured Active Galaxies
Kevin N. Hainline, Ryan C. Hickox, Chien-Ting Chen +4
We explore the gas ionization and kinematics, as well as the optical--IR spectral energy distributions for UGC 11185, a nearby pair of merging galaxies hosting obscured active gala…
