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…
