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…

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…

Monitoring AGNs with H Asymmetry. V. Long-term Variation and Evolution of the Broad H Emission-Line Profiles

Feng-Na Fang, Pu Du, Michael S. Brotherton +40

The physical origins of the diverse emission-line asymmetries observed in the spectra of active galactic nuclei (AGNs) remain incompletely understood. Monitoring the temporal varia…

Monitoring AGNs with H Asymmetry. IV. First Reverberation Mapping Results of 14 AGNs

T. E. Zastrocky, Michael S. Brotherton, Pu Du +41

We report first-time reverberation mapping results for 14 AGNs from the ongoing Monitoring AGNs with H Asymmetry campaign (MAHA). These results utilize optical spectra obtained…

X-ray properties of reverberation-mapped AGNs with super-Eddington accreting massive black holes

Jaya Maithil, Michael S. Brotherton, Ohad Shemmer +7

The X-ray properties of Active Galactic Nuclei (AGNs) depend on their underlying physical parameters, particularly the accretion rate. We identified eight reverberation-mapped AGNs…
