Inverse Multview I: Multi-Calibrator inverse phase referencing for Microarcsecond VLBI Astrometry
Lucas J. Hyland, Mark J. Reid, Simon P. Ellingsen +5
Very Long Baseline Interferometry (VLBI) astrometry is a well established technique for achieving as parallax accuracies at frequencies well above 10~GHz. At lower frequen…
PKS 1954-388: RadioAstron Detection on 80,000 km Baselines and Multiwavelength Observations
P. G. Edwards, Y. Y. Kovalev, R. Ojha +24
We present results from a multiwavelength study of the blazar PKS 1954-388 at radio, UV, X-ray, and gamma-ray energies. A RadioAstron observation at 1.66 GHz in June 2012 resulted…
Parallaxes of 6.7-GHz Methanol Masers towards the G305.2 High-Mass Star Formation Region
V Krishnan, S P Ellingsen, M J Reid +5
We have made measurements to determine the parallax and proper motion of the three 6.7-GHz methanol masers G305.2000.019, G305.2020.208 and G305.2080.206. The combined par…
BL LAC PKSB1144-379 an extreme scintillator
R. J. Turner, S. P. Ellingsen, S. S. Shabala +4
Rapid variability in the radio flux density of the BL Lac object PKSB1144-379 has been observed at four frequencies, ranging from 1.5 to 15 GHz, with the VLA and the University of…
The first resolved imaging of milliarcsecond-scale jets in Circinus X-1
J. C. A. Miller-Jones, A. Moin, S. J. Tingay +7
We present the first resolved imaging of the milliarcsecond-scale jets in the neutron star X-ray binary Circinus X-1, made using the Australian Long Baseline Array. The angular ext…
