Broad-band Spectral Modeling of Large-Scale X-ray Jets in High-Redshift Quasars: An MHD-Informed Approach

Patryk Liniewicz, Łukasz Stawarz, C. C. Cheung +2

We present a systematic spectral analysis of kiloparsec-scale jets in high-redshift quasars, modeling their radio-to-X-ray emission as synchrotron radiation and inverse-comptonizat…

A Weak Fe K Emission Line in the Broad-Line Radio Galaxy 3C 111 Observed with XRISM: An Ionized Wind Absorption Feature?

Kouichi Hagino, Motoki Kino, Lukasz Stawarz +3

We present the results of an observation of the broad-line radio galaxy 3C 111 with the X-Ray Imaging and Spectroscopy Mission (XRISM). The unprecedentedly high spectral resolution…

Prospects for the detection of gamma rays using Cherenkov telescopes enhanced by a ground array observatory

C. Alispach, A. Araudo, A. Bakalová +67

We study through detailed simulated data and their optimized analysis the expected performance of the Single-Mirror Small-Size imaging atmospheric Cherenkov Telescopes (SST-1M) pot…

VLASS-based survey of transition state galaxies and their relationship to compact peaked-spectrum radio sources

M. Kunert-Bajraszewska, A. Krauze, A. E. Kimball +6

We present multi-frequency and high-resolution studies of a sample of 24 radio transients sources discovered by comparing the NRAO VLA Sky Survey (NVSS) and Very Large Array Sky Su…

Curvature in the very-high energy gamma-ray spectrum of M87

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +132

The radio galaxy M87 is a variable very-high energy (VHE) gamma-ray source, exhibiting three major flares reported in 2005, 2008, and 2010. Despite extensive studies, the origin of…
