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…
A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294
Shifra Mandel, Kaya Mori, Paul A. Draghis +37
For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…
Observation of gamma rays up to 320 TeV from the middle-aged TeV pulsar wind nebula HESS J1849000
M. Amenomori, S. Asano, Y. W. Bao +115
Gamma rays from HESS J1849000, a middle-aged TeV pulsar wind nebula (PWN), are observed by the Tibet air shower array and the muon detector array. The detection significance of…
The universal shape of the X-ray variability power spectrum of AGN up to
M. Paolillo, I. E. Papadakis, W. N. Brandt +12
We study the ensemble X-ray variability properties of Active Galactic Nuclei (AGN) over a large range of timescales (20 ks 14 yrs), redshift (), lu…
Study of variability in long-term multiwavelength optical lightcurves of blazar AO 0235+164
Abhradeep Roy, Alok C. Gupta, Varsha R. Chitnis +9
We present a long-term and intraday variability study on optical multiwaveband () data from the blazar AO 0235+164 collected by various telescopes for 44 years (19…
GW190521 and the GWTC-1 Events: Implication on the Black Hole Mass Function of Coalescing Binary Black Hole Systems
Yuan-Zhu Wang, Shao-Peng Tang, Yun-Feng Liang +5
With the black hole mass function (BHMF; assuming an exponential cutoff at a mass of ) of coalescing binary black hole systems constructed with the events detecte…
