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…

PACHA: Probing AGN Coronae with High-redshift AGN

Xiurui Zhao, Elias Kammoun, Marco Ajello +18

The X-ray emission of active galactic nuclei (AGN) is generally attributed to inverse Compton scattering of accretion-disk photons by hot electrons in a compact corona. In local AG…

Transient Relativistic Iron Emission Line from an X-ray Flaring Supermassive Black Hole

Xiurui Zhao, Marco Ajello, Francesca Civano +16

We report the discovery of the first transient relativistic iron Kα line in an Active Galactic Nucleus (AGN) J1047+5907. The line was detected 21.5 days (rest-frame) after an X-ray…

Dwarf Galaxy Number Counts within 25 Mpc: Predictions from Local Group Analogues in TNG50

Evangela E. Shread, Joanna M. Piotrowska, Daniel R. Weisz +2

The modern generation of wide-field galaxy surveys, such as LSST, Euclid and Roman, will enable studies of dwarf galaxies beyond the Local…

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…
