VLA Observations at 6 and 19 GHz of a Complete Sample of Radio Loud Quasars with redshifts between 2.5 and 5.28: II. Sample definition, radio images, and analysis
John F. C. Wardle, Mark Birkinshaw, Diana M. Worrall +4
We present high resolution (subarcsecond) observations at 6.2 and 19.6 GHz made with the Karl G. Jansky Very Large Array of 113 radio-loud quasars that form a complete flux limited…
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…
The JWST View of Cygnus A: Jet-Driven Coronal Outflow with a Twist
Patrick M. Ogle, B. Sebastian, A. Aravindan +29
We present first results from James Webb Space Telescope (JWST) Near-Infrared Spectrograph (NIRSpec), Mid-Infrared Instrument (MIRI), and Keck Cosmic Webb Imager (KCWI) integral fi…
DRUID: Source Detection and Deblending in Astronomical Images with Persistent Homology
R. A. Shaw, S. Fotopoulou, M. Birkinshaw +2
Source detection is a vital part of any astronomical survey analysis pipeline. In addition, a versatile source finder that can recover and handle sources of all morphological types…
A Multiwavelength Portrait of the 3C 220.3 Lensed System
Sóley Ã. Hyman, Belinda J. Wilkes, S. P. Willner +10
The 3C 220.3 system is a rare case of a foreground narrow-line radio galaxy ("galaxy A," ) lensing a background submillimeter galaxy (). New spe…
