The disk luminosity deficit as a tracer of receding disk during Soft-to-Hard transitions in Black Hole X-ray Binaries
Sai-En Xu, Bei You, Yi Long +4
Tracing the evolution of the thin accretion disk during the soft-to-hard state transition in black hole X-ray binaries (BHXRBs) remains difficult because conventional spectral esti…
Constraining Disk-to-Corona Power Transfer Fraction, Soft X-ray Excess Origin, and Black Hole Spin Population of Type-1 AGN across Mass Scales
Labani Mallick, Ciro Pinto, John Tomsick +6
Understanding the nature of the accretion disk, its interplay with the X-ray corona, and assessing black hole spin demographics remain open challenges in astrophysics. In this pape…
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…
BlazEr1: The eROSITA Blazar Catalog. Blazars and Blazar Candidates in the First eROSITA Survey
S. Haemmerich, A. Gokus, F. McBride +28
Aims. eROSITA, on board the Spectrum Roentgen Gamma (SRG) spacecraft, performed its first X-ray all-sky survey (eRASS1) between December 2019 and June 2020. It detected about 93000…
Optical and cm follow-ups of the Changing-Look event in Mkn 590
Biswaraj Palit, Abhijeet Borkar, Agata RóżaÅska +5
The Changing-Look active galactic nucleus Mkn 590 is currently in a rejuvenated state, exhibiting a contemporaneous flux rise across X-rays, UV, optical and cm wavelengths. In this…
