Magnetic rigidity reveals the PeVatron acceleration region in SS 433
Jie Liao, Wancheng Xu, Lang Cui +10
PeVatrons are cosmic accelerators capable of driving particles to petaelectronvolt (PeV) energies. Recently, microquasar jets have emerged as compelling Galactic PeVatron candidate…
Synchrotron Self-Absorption Spectral Modeling Reveals a Magnetically Driven Shock-in-Jet Scenario in Blazar 1156+295
Wancheng Xu, Lang Cui, Tao An +6
Unveiling the launching and driving mechanisms of powerful jets in active galactic nuclei (AGNs) is crucial for understanding the co-evolution of supermassive black holes (SMBHs) a…
Sub-Parsec Acceleration and Collimation of NGC 4261's Twin Jets
Xi Yan, Lang Cui, Kazuhiro Hada +6
We report the first robust evidence for a co-spatial sub-parsec acceleration and collimation zone (ACZ) in the twin jets of the nearby low-luminosity active galactic nucleus (LLAGN…
From Equipartition to Curvature: The Spectral Evolution of 4FGL Blazars
Muhammad S. Anjum, Shu-Jin Hou, Liang Chen +2
We investigate the evolution of spectral energy distribution (SED) and underlying electron energy distribution (EED) by modeling the nearly simultaneous broadband spectra of select…
Signature of Seyfert-like component in a blazar 3C 273 and its reflection-based explanation
Haritma Gaur, Main Pal, Muhammad S. Anjum +4
We present the results of blazar 3C 273 obtained from simultaneous observations obtained using XMM-Newton and NuSTAR satellites during the period 2015-2019 in five epochs. When the…
Spectral Energy Distribution Variability of the Blazar OJ 287 during 2009-2021
Wenwen Zuo, Alok C. Gupta, Minfeng Gu +11
Using nearly simultaneous radio, near-infrared, optical, and ultraviolet data collected since 2009, we constructed 106 spectral energy distributions (SEDs) of the blazar OJ 287. Th…
