Identification and Characterization of a Large Sample of Distant Active Dwarf Galaxies in XMM-SERVS
Fan Zou, W. N. Brandt, Qingling Ni +10
Active dwarf galaxies are important because they contribute to the evolution of dwarf galaxies and can reveal their hosted massive black holes. However, the sample size of such sou…
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…
Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE

We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…
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

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…
A Chandra Virgo cluster survey of spiral galaxies. I. Introduction to the survey and a new ULX sample
Roberto Soria, Mari Kolehmainen, Alister W. Graham +10
We present an analysis of the ultraluminous X-ray source (ULX) population in 75 Virgo cluster late-type galaxies, including all those with a star formation rate >~ 1 M_{sun}/yr and…
Central X-ray point-sources found to be abundant in low-mass, late-type galaxies predicted to contain an intermediate-mass black hole
Alister W. Graham, Roberto Soria, Benjamin L. Davis +5
Building upon three late-type galaxies in the Virgo cluster with both a predicted black hole mass of less than 10 M and a centrally-located X-ray point-source,…
Potential Black Hole Seeding of the Spiral Galaxy NGC 4424 via an Infalling Star Cluster
Alister W. Graham, Roberto Soria, Bogdan C. Ciambur +2
Galaxies can grow through their mutual gravitational attraction and subsequent union. While orbiting a regular high-surface-brightness galaxy, the body of a low-mass galaxy can be…
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…
