25 Years of Mrk 421 with XMM-Newton: Unveiling Structured Jets and Energy-Dependent Escape
Tek P. Adhikari, Gopal Bhatta, Sangeetha Kizhakkekalam +4
We present a long-term X-ray spectral and timing analysis of the TeV blazar Mrk~421 based on nearly a quarter century of archival \textit{XMM-Newton}/pn observations obtained betwe…
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…
Large-amplitude modulations and hours-timescale variability in the early X-ray light curve of a tidal disruption flare
A. Malyali, A. Rau, P. Baldini +11
We present new X-ray, optical, and UV observations of the tidal disruption event candidate eRASSt J234402.9-352640, (hereafter J2344). Between 50 and 60 days after peak optical bri…
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…
