PKS 2123-463: a confirmed gamma-ray blazar at high redshift
F. D'Ammando, A. Rau, P. Schady +11
The flat spectrum radio quasar (FSRQ) PKS 2123-463 was associated in the First Fermi-LAT source catalog with the gamma-ray source 1FGL J2126.1-4603, but when considering the full f…
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…
Why Do Compact Active Galactic Nuclei at High Redshift Scintillate Less?
J. Y. Koay, J. -P. Macquart, B. J. Rickett +7
The fraction of compact active galactic nuclei (AGNs) that exhibit interstellar scintillation (ISS) at radio wavelengths, as well as their scintillation amplitudes, have been found…
ATCA monitoring of gamma-ray loud AGN
J. Stevens, P. G. Edwards, R. Ojha +8
As a critical part of the Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry (TANAMI) program, in November 2007 the Australia Telescope Compact Array (ATCA)…
First cosmological constraints on the proton-to-electron mass ratio from observations of rotational transitions of methanol
S. P. Ellingsen, M. A. Voronkov, S. L. Breen +1
We have used the Australia Telescope Compact Array to measure the absorption from the 2(0) - 3(-1}E 12.2 GHz transition of methanol towards the z=0.89 lensing galaxy in the PKS B 1…
