Brisken, Walter F., Macquart, Jean-Pierre, Gao, Jian-Jian, Rickett, Barney, Coles, William, Deller, Adam, ...
We have invented a novel technique to measure the radio image of a pulsar scattered by the interstellar plasma with 0.1 mas resolution. We extend the "secondary spectrum" analysis of parabolic arcs...
The Murchison Widefield Array: Design Overview (2009)
Lonsdale, Colin J., Cappallo, Roger J., Morales, Miguel F., Briggs, Frank H., Benkevitch, Leonid, Bowman, Judd D., ...
The Murchison Widefield Array (MWA) is a dipole-based aperture array synthesis telescope designed to operate in the 80-300 MHz frequency range. It is capable of a wide range of science...
The FRII Broad Line Seyfert 1 Galaxy: PKSJ 1037-2705 (2008)
Punsly, Brian, Clarke, Tracy E., Tingay, Steven, Gutierrez, Carlos M., Rasmussen, Jesper, Colbert, Ed
In this article, we demonstrate that PKSJ 1037-2705 has a weak accretion flow luminosity, well below the Seyfert1/QSO dividing line, weak broad emission lines (BELs) and moderately powerful FRII...
Very long baseline interferometry detection of an Infrared-Faint Radio Source (2008)
Ray P. Norris, Steven Tingay, Chris Phillips, Enno Middelberg, Adam Deller
Over the last two years, in collaboration with the Spitzer Wide-area
The VSOP 5 GHz active galactic nucleus survey. V. Imaging results for the remaining 140 (2008)
In 1997 February, the Japanese radio astronomy satellite HALCA was launched to provide the space-bourne element for the VLBI Space Observatory Program (VSOP) mission. Approximately 25% of the mission...
The FR II broad-line seyfert 1 galaxy: PKS J1037-2705 (2008)
Punsly, B., Clarke, T., Tingay, Steven, Gutierrez, C., Rasmussen, J., Colbert, E.
In this article we demonstrate that PKS J1037-2705 has a weak accretion flow luminosity, well below the Seyfert 1/QSO dividing line, weak broad emission lines (BELs), and moderately powerful FR II...
Tingay, Steven, Lenc, E., Brunetti, G., Bondi, M.
Images made with the Very Long Baseline Array (VLBA) have resolved the region in a nearby (z = 0.035) radio galaxy, Pictor A, where the relativistic jet that originates at the nucleus terminates in...
A deep, high-resolution survey of the low-frequency radio sky (2008)
Lenc, E., Garrett, M., Wucknitz, O., Anderson, J., Tingay, Steven
We report on the first wide-field, very long baseline interferometry (VLBI) survey at 90 cm. The survey area consists of two overlapping 28 deg2 fields centered on the quasar J0226+3421 and the...
Very long baseline interferometry detection of an Infrared-Faint Radio Source (2007)
Norris, Ray P., Tingay, Steven, Phillips, Chris, Middelberg, Enno, Deller, Adam, Appleton, Philip N.
Infrared-Faint Radio Sources represent a new and unexpected class of object which is bright at radio wavelengths but unusually faint at infrared wavelengths. If, like most mJy radio sources, they...

PKS 1018-42: A Powerful Kinetically Dominated Quasar (2006)
We have identified PKS 1018-42 as a radio galaxy with extraordinarily powerful jets, over twice as powerful as any 3CR source of equal or lesser redshift except for one (3C196). It is perhaps the...
PKS 0743$-$67: An Ultra-luminous Accretion Disk and a High Kinetic Luminosity Jet (2005)
In this letter, deep radio observations of the quasar PKS 0743$-$67 are presented that reveal a central engine capable of driving jets with enormous kinetic luminosity, $Q>4.1 \times...
PKS 1622-253: A Weakly Accreting, Powerful Gamma Ray Source (2005)
Punsly, Brian, Rodriguez, Luis, Tingay, Steven, Cellone, Sergio
In this Letter, we discuss new deep radio observations of PKS 1622-253 and their implications for the energetics of the central engine that powers this strong high energy gamma-ray source. Combining...
