Dynamic Accretion Disk-Corona Connection and Broad Fe K Variability in Mrk 766 Revealed by Time-Resolved High Resolution X-Ray Spectroscopic Analysis
Ayon Mondal, Tathagata Saha, Arijit Sar +1
We present a multi-epoch, primarily X-ray study of the narrow-line Seyfert 1 (NLSy1) galaxy Mrk~766 by combining archival \textit{XMM-Newton} observations spanning nearly two decad…
eRASSU J043115.8-711730 :the first pulsating symbiotic super-soft X-ray source in the Magellanic Bridge
Tathagata Saha, Chandreyee Maitra, Philip Charles +9
The Magellanic Bridge stellar population is a relic of the tidal interaction between the Large and Small Magellanic Clouds. A comprehensive view of the evolution of the Bridge stel…
A Changing-Look Seyfert Discovered by eROSITA Reveals a Two-Component Broad-Line Region
Alex Markowitz, Mirko Krumpe, David Homan +12
Extreme sudden changes in the flow of accreting gas onto SMBHs manifest themselves via large-amplitude continuum variability and changes to broad Balmer emission profiles, driving…
A break in the X-ray loudness of Markarian 590: evidence for an AGN spectral state transition?
B. Palit, A. Rozanska, A. G. Markowitz +8
Using decade-long multi-band {\it Swift} observations of the changing-look AGN Markarian 590, we identify a clear break in the dependence of the X-ray loudness parameter $α_{\rm ox…
