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…
Very-high-energy -ray emission from young massive star clusters in the Large Magellanic Cloud
F. Aharonian, F. Ait Benkhali, J. Aschersleben +129
The Tarantula Nebula in the Large Magellanic Cloud is known for its high star formation activity. At its center lies the young massive star cluster R136, providing a significant am…
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…
On the Origin of the X-ray Emission in Heavily Obscured Compact Radio Sources
Dominika Ł. Król, Małgosia Sobolewska, Łukasz Stawarz +4
X-ray continuum emission of active galactic nuclei (AGNs) may be reflected by circumnuclear dusty tori, producing prominent fluorescence iron lines at X-ray frequencies. Here we di…
Multiwavelength Observations of the Blazar PKS~0735+178 in Spatial and Temporal Coincidence with an Astrophysical Neutrino Candidate IceCube-211208A
M. Pohl, K. Mori
We report on multiwavelength target-of-opportunity observations of the blazar PKS 0735+178, located 2.2 degrees away from the best-fit position of the IceCube neutrino event 211208…
