The Millimeter/X-ray Relation in Rapidly Accreting Supermassive Black Holes at
Sophie M. Venselaar, Claudio Ricci, Santiago Del Palacio +12
A tight correlation between nuclear millimeter and X-ray emission has recently been found in nearby () and low-Eddington ratio () radio-quiet Active Ga…
UGC 2369S: a Kpc Scale Triple Merger Candidate Identified in a Nearby Luminous Infrared Galaxy
Yuanze Ding, Michael J. Koss, Fiona A. Harrison +12
We present high spatial resolution (1.0''), multi-wavelength observations of UGC 2369S, a nearby luminous infrared galaxy showing three distinct cores separated on kpc sc…
BASS. LI. Cool gas supply of HI-massive local Seyfert galaxies
Jeein Kim, Aeree Chung, O. Ivy Wong +19
We present neutral atomic hydrogen (HI) imaging observations of 22 HI-rich (), hard X-ray-selected local Seyferts to explore how cool gas is su…
An Investigation of 5-year Simultaneous X-ray and Radio Light Curves of the Dwarf Seyfert Galaxy UGC 6728
Krista Lynne Smith, Macon Magno, Michael Koss
We present serendipitous simultaneous radio and X-ray light curves of the dwarf Seyfert galaxy UGC 6728 spanning 5 years. The X-ray light curve exhibits a flaring period, followed…
VLA FRAMEx. III. Circumnuclear Radio Emission Mechanisms in Hard X-ray Selected Active Galactic Nuclei
Andrew J. Sargent, Alexander J. van der Horst, Megan C. Johnson +5
We present Stokes I continuum analysis for a volume-limited sample () of hard X-ray selected active galactic nuclei (AGNs) using GHz observations with the Karl…
BASS LII: The prevalence of double-peaked broad lines at low accretion rates among hard X-ray selected AGN
Charlotte Ward, Michael J. Koss, Michael Eracleous +18
A fraction of active galactic nuclei (AGN) have double-peaked H, H and Mg II broad lines attributed to emission from rotating gas in the accretion disk. Using optical spectro…
BASS. XLIX. Characterization of highly luminous and obscured AGNs: local X-ray and [NeV]3426 emission in comparison with the high-redshift Universe
Alessandro Peca, Michael J. Koss, Kyuseok Oh +21
We present a detailed analysis of the most luminous and obscured Active Galactic Nuclei (AGNs) detected in the ultra-hard X-ray band (14-195 keV) by Swift/BAT. Our sample comprises…
Millimeter emission from supermassive black hole coronae
S. del Palacio, C. Yang, S. Aalto +28
Active Galactic Nuclei (AGN) host accreting supermassive black holes (SMBHs). The accretion can lead to the formation of a hot, X-ray emitting corona close to the SMBH capable of a…
BASS XLVII: 22 GHz Radio Atlas of Swift-BAT Selected AGN
Macon Magno, Krista L. Smith, O. Ivy Wong +16
We present the third phase of the largest high-frequency, high-resolution imaging survey of 231 nearby, hard X-ray selected AGN, with a very high detection fraction. T…
The Nature of the IMBH Candidate CXO~J133815.6+043255: High-Frequency Radio Emission
Krista Lynne Smith, Macon Magno, Ashutosh Tripathi
The ultra-luminous X-ray source CXO~J133815.6+043255 is a strong candidate for a bona-fide intermediate mass black hole, residing in the outskirts of NGC~5252. We present 22~GHz ra…
UGC 4211: A Confirmed Dual Active Galactic Nucleus in the Local Universe at 230 pc Nuclear Separation
Michael J. Koss, Ezequiel Treister, Darshan Kakkad +23
We present multi-wavelength high-spatial resolution (~0.1'', 70 pc) observations of UGC 4211 at z=0.03474, a late-stage major galaxy merger at the closest nuclear separation yet fo…
Curvature-slope correlation of nuclear symmetry energy and its imprints on the crust-core transition, radius and tidal deformability of canonical neutron stars
Bao-An Li, Macon Magno
Background: The nuclear symmetry energy encodes information about the energy necessary to make nuclear systems more neutron-rich. While its slope parameter L at the sa…
A Study of H Line Profile Variations in Lyr
Richard Ignace, Sharon Gray, Macon Magno +2
We examine over 160 archival H spectra from the Ritter Observatory for the interacting binary ~Lyr obtained between 1996 and 2000. The emission is characteristically double-p…
Diffuse X-ray-emitting Gas in Major Mergers
Beverly J. Smith, Kristen Campbell, Curtis Struck +5
Using archived data from the Chandra X-ray telescope, we have extracted the diffuse X-ray emission from 49 equal-mass interacting/merging galaxy pairs in a merger sequence, from wi…
