The parsec-scale jet of PKS 0637-752 (2006)
Edwards, Philip G., Piner, B. Glenn, Tingay, Steven J., Lovell, James E. J., Kataoka, Jun, Ojha, Roopesh, ...
Chandra observations of the quasar PKS 0637-752 during its checkout phase resulted in the unexpected detection of a luminous kiloparsec-scale X-ray jet. The apparent superluminal speed of this jet on...

Discovery of a Sub-Parsec Radio counterjet in the Nucleus of Centarus A (2004)
Jones, Dayton L., Tingay, Steven J., Murphy, David W., Meier, David L., Jauncey, David L., Reynolds, John E., ...
A sub-parsec scale radio counterjet has been detected in the nucleus of the closest radio galaxy, Centarus A (NGC 5128), with VLBI imaging at 2.3 and 8.4 GHz.
The Radio Variability of the Gravitational Lens PMN J1838-3427 (2004)
Winn, Joshua N., Lovell, James E. J., Bignall, Hayley, Gaensler, Bryan M., Getts, Tracy J., Kedziora-Chudczer, Lucyna, ...
We present the results of a radio variability study of the gravitational lens PMN J1838-3427. Our motivation was to determine the Hubble constant by measuring the time delay between variations of the...
The Quintuple Quasar: Radio and Optical Observations (2003)
Winn, Joshua N., Kochanek, Christopher S., Keeton, Charles R., Lovell, James E. J.
We present results from high-resolution radio and optical observations of PMN J0134-0931, a gravitational lens with a unique radio morphology and an extremely red optical counterpart. Our data...
PMN J0134-0931: A gravitationally lensed quasar with an unusual radio morphology (2001)
Winn, Joshua N., Lovell, James E. J., Chen, Hsiao-Wen, Fletcher, Andre B., Hewitt, Jacqueline N., Patnaik, Alok R., ...
The radio-loud quasar PMN J0134-0931 was discovered to have an unusual morphology during our search for gravitational lenses. In VLA and MERLIN images, there are 5 compact components with maximum...
PMN J1632-0033: A new gravitationally lensed quasar (2001)
Winn, Joshua N., Morgan, Nicholas D., Hewitt, Jacqueline N., Kochanek, Christopher S., Lovell, James E. J., Patnaik, Alok R., ...
We report the discovery of a gravitationally lensed quasar resulting from our survey for lenses in the southern sky. Radio images of PMN J1632-0033 with the VLA and ATCA exhibit two compact,...
