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…
ASKAP J005512.2-255834: A Luminous, Long-Lived Radio Transient at z = 0.1 -- an Orphan Afterglow or an off-nuclear TDE from an IMBH?
Ashna Gulati, Tara Murphy, David L. Kaplan +24
We report the discovery of a slowly evolving, extragalactic radio transient, ASKAP J005512.2--255834 (hereafter ASKAP J0055-2558), identified using the Australian SKA Pathfinder in…
ALMA discovery of Punctum -- a highly polarized mm source in nuclear starburst galaxy NGC 4945
E. Shablovinskaia, C. Ricci, C-S. Chang +9
We report the discovery of a highly polarized millimeter (mm) continuum source in the central region of NGC 4945, identified through ALMA Band 3 observations. This starburst Seyfer…
The luminosity history of fading local quasars over 10 years as observed by VLT/MUSE
C. Finlez, E. Treister, F. Bauer +10
We present a comprehensive study of five nearby active galaxies featuring large (tens of kpc) extended emission-line regions (EELRs). The study is based on large-format integral fi…
AGN with massive black holes have closer galactic neighbors: k-Nearest-Neighbor statistics of an unbiased sample of AGN at z~0.03
A. Mhatre, M. C. Powell, S. Yuan +10
The large-scale environments of active galactic nuclei (AGN) reveal important information on the growth and evolution of supermassive black holes (SMBHs). Previous AGN clustering m…
