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…

Numerical Approximation Methods for Antenna Radiation Patterns for Motus Wildlife Tracking Systems

Erik Carlson, Douglas Gobeille, Robert Deluca +1

As plans for offshore wind energy development increase in the US, the developing methods to monitor migratory birds and bats offshore is an important area of research. To contribut…

Discovery of Candidate X-ray Jets in High-Redshift Quasars

Bradford Snios, Daniel A. Schwartz, Aneta Siemiginowska +8

We present Chandra X-ray observations of 14 radio-loud quasars at redshifts , selected from a well-defined sample. All quasars are detected in the 0.5-7.0 keV energy ban…

Relativistic X-ray jets at high redshift

Daniel A Schwartz, Aneta Siemiginowska, Diana M Worrall +6

Powerful radio sources and quasars emit relativistic jets of plasma and magnetic fields that travel hundreds of kilo-parsecs, ultimately depositing energy into the intra- or inter-…

VLA Observations of a Complete Sample of Radio Loud Quasars between redshifts 2.5 and 5.28: I. high-redshift sample summary and the radio images

Doug B. Gobeille, John F. C. Wardle, C. C. Cheung

We present high resolution (arcsecond or better) observations made with the Karl G. Jansky Very Large Array of 123 radio-loud quasars with redshifts in the range $2.5 \leq z \leq 5…
