The next-generation space VLBI mission, VSOP-2, is expected to provide unprecedented spatial resolutions at 8.4, 22, and 43GHz. In this report, phase referencing with VSOP-2 is examined in detail...
Two decades of pulsar timing of Vela (2006)
Dodson, Richard, Lewis, Dion, McCulloch, Peter
Pulsar timing at the Mt Pleasant observatory has focused on Vela, which can be tracked for 18 hours of the day. These nearly continuous timing records extend over 24 years allowing a greater insight...
Milli-arcsecond--scale Spectral Properties and Jet Motions in M87 (2005)
Dodson, Richard, Edwards, Philip G., Hirabayashi, Hisashi
We have combined high resolution VLBI Space Observatory Programme (VSOP) data at 1.6 and 4.8 GHz with Very Long Baseline Array (VLBA) data at higher frequencies and with similar resolutions to study...
The Complex Wind Torus and Jets of PSR B1706-44 (2005)
Romani, Roger W., Ng, C. -Y., Dodson, Richard, Brisken, Walter
We report on Chandra ACIS imaging of the pulsar wind nebula (PWN) of the young Vela-like PSR B1706-44, which shows the now common pattern of an equatorial wind and polar jets. The structure is...
Measurement of core-shifts with astrometric multi-frequency calibration (2005)
Rioja, Maria J., Dodson, Richard, Porcas, Richard W., Suda, Hiroshi, Colomer, Francisco
VLBI is unique, among the space geodetic techniques, in its contribution to defining and maintaining the International Celestial Reference Frame, providing precise measurements of coordinates of...
Measurement of the proper motion of Vela with the LBA (2004)
Dodson, Richard, Legge, David, McCulloch, Peter, Reynolds, John
The first accurate measurements of Vela's proper motion were produced using the Parkes-Tidbinbilla Interferometer (PTI) (Bailes et al 1989). This 275 km baseline at 1.6 GHz gave a resolution of 140...
The Vela pulsar, the key? (2004)
Dodson, Richard, Lewis, Dion, Legge, David, McCulloch, Peter, Reynolds, John, McConnell, David, ...
Of all pulsars known Vela has been one of the most productive in terms in understanding pulsars and their characteristics. We present the latest results derived from Australian telescopes. These...
The Vela Pulsar Wind Nebula at 6cm (2001)
Lewis, Dion, Dodson, Richard, McConnell, David, Deshpande, Avinash
Observations using the Australia Telescope Compact Array at a wavelength of 6 cm have uncovered the radio counterpart to the compact X-ray nebula surrounding the Vela pulsar. Two lobes were found...
