Chandra X-ray imaging and IC/CMB model for the inner jet of PKS 0637-752
Jaya Maithil, Daniel A. Schwartz, Aneta Siemiginowska +2
We present the X-ray surface brightness maps of the jet from the quasar PKS 0637-752, using two epochs of archival Chandra observations (1999 and 2017). We present, for the first t…
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…
The LIRA-Ising Model: Estimating the boundaries of irregularly shaped X-ray sources
Kathryn McKeough, Vinay L. Kashyap, Aneta Siemiginowska +5
Mapping the boundary of an extended source is a key step in the study of its morphology. The background contamination and statistical fluctuations of typical astronomical images ma…
The changing impact of radio jets as they evolve: The view from the cold gas
Tom Oosterloo, Raffaella Morganti, Clive Tadhunter +3
We present ALMA CO(1-0) and CO(3-2) observations of a powerful young radio galaxy, PKS 0023-26, hosted by a far-infrared bright galaxy. The galaxy has a luminous optical AGN and a…
Investigating the emission mechanism in the spatially-resolved jet of two z 3 radio-loud quasars
Jaya Maithil, Daniel A. Schwartz, Aneta Siemiginowska +9
This study focuses on high-redshift, z > 3, quasars where resolved X-ray jets remain underexplored in comparison to nearby sources. Building upon previous work, we identify and con…
NuSTAR observations of a varying-flux quasar in the Epoch of Reionization
Lea Marcotulli, Thomas Connor, Eduardo Bañados +13
With enough X-ray flux to be detected in a 160s scan by SRG/eROSITA, the quasar CFHQS J142952+544717 is, by far, the most luminous X-ray source known at . We pres…
