eRASSU J043115.8-711730 :the first pulsating symbiotic super-soft X-ray source in the Magellanic Bridge
Tathagata Saha, Chandreyee Maitra, Philip Charles +11
The paper reports the discovery and multi-wavelength analysis of J0431-71, the first pulsating symbiotic super-soft X-ray source in the Magellanic Bridge, identifying it as a white…
The spectral state transition of Mkn 590, a potential link between AGNs and X-ray binaries?
B. Palit, A. Rozanska, A. G. Markowitz +8
Using the decade-long multi-band \textit{Swift} observations of the changing look AGN Markarian~590, we capture a clear state transition associated with its recent changing look ev…
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…
Multiwavelength study of extreme variability in LEDA 1154204: A changing-look event in a type 1.9 Seyfert
T. Saha, A. Markowitz, D. Homan +16
Context. Multiwavelength studies of transients in actively accreting supermassive black holes have revealed that large-amplitude variability is frequently linked to significant cha…
The Close AGN Reference Survey (CARS). Long-term spectral variability study of the changing look AGN Mrk 1018
T. Saha, M. Krumpe, A. Markowitz +9
Changing-look AGNs (CLAGN) are accreting supermassive black hole systems that undergo variations in optical spectral type, driven by major changes in accretion rate. Mrk 1018 has u…
