J0011+3443: a GPS compact symmetric object, gravitational lens, or dual AGN?
Efthalia Traianou, Tingting Liu, Roman Gold +1
We present new multi-frequency VLBA observations of J0011+3443 (TXS 0008+344, z = 0.89) at 2.3, 4.9, 8.5, and, for the first time, 23.6 GHz. The source consists of two compact comp…
An XMM-Newton Analysis of the Supermassive Black Hole Binary Candidate MCG+11--11--032
Yash A. Gursahani, Tingting Liu, Richard Mushotzky +2
We investigate the possibility of a binary supermassive black hole system at the center of MCG+11--11--032, a local (z = 0.036) Seyfert 2 galaxy. Prior work with stacked Swift/XRT…
BASS LV. Connecting X-ray variability with AGN physical properties and a new path to Cosmological distances
Matilde Signorini, Federica Ricci, Alessia Tortosa +18
X-ray variability is a well-established characteristic of active galactic nuclei (AGN), known to correlate inversely with both the supermassive black hole mass and luminosity, alth…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
Continuum Reverberation Mapping of Accretion Disks Surrounding Supermassive Black Hole Binaries: Observational Signatures
Yi-Xin Fu, Yan-Rong Li, Jian-Min Wang +9
It has remained challenging to reliably identify sub-parsec supermassive black hole binaries (SMBHBs), despite them being expected to be ubiquitous. We propose a new method using m…
Chandra Discovery of a Candidate Hyper-Luminous X-ray Source in MCG+11-11-032
Adi Foord, Francesca Civano, Julia M. Comerford +9
We present a multi-wavelength analysis of MCG+11-11-032, a nearby AGN with the unique classification of both a binary and a dual AGN candidate. With new Chandra observations we aim…
Prospects for Time-Domain and Multi-Messenger Science with AXIS
The AXIS Time-Domain, Multi-Messenger Science Working Group, : +19
The Advanced X-ray Imaging Satellite (AXIS) promises revolutionary science in the X-ray and multi-messenger time domain. AXIS will leverage excellent spatial resolution (<1.5 arcse…
Tracking Supermassive Black Hole Mergers from kpc to sub-pc Scales with AXIS
Adi Foord, Nico Cappelluti, Tingting Liu +8
We present an analysis showcasing how the Advanced X-ray Imaging Satellite (AXIS), a proposed NASA Probe-class mission, will significantly increase our understanding of supermassiv…
BASS-XL: X-ray variability properties of unobscured Active Galactic Nuclei
Alessia Tortosa, Claudio Ricci, Patricia Arévalo +15
We investigate the X-ray variability properties of Seyfert1 Galaxies belonging to the BAT AGN Spectroscopic Survey (BASS). The sample includes 151 unobscured (N c…
