Revealing HI gas in emission and absorption on pc to kpc scales in a galaxy at z ~ 0.017
N. Gupta, R. Srianand, J. S. Farnes +6
We present a detailed study of the quasar-galaxy pair: J1243+4043 - UGC07904. The sight line of the background quasar ( = 1.5266) passes through a region of the galaxy (=…
Radio Polarization Properties of Quasars and Active Galaxies at High Redshifts
Tessa Vernstrom, Bryan Gaensler, Valentina Vacca +3
We present the largest ever sample of radio polarization properties for sources, with 14 sources having significant polarization detections. Using wideband data from the Karl…
A Unifying Theory of Dark Energy and Dark Matter: Negative Masses and Matter Creation within a Modified CDM Framework
J. S. Farnes
Dark energy and dark matter constitute 95% of the observable Universe. Yet the physical nature of these two phenomena remains a mystery. Einstein suggested a long-forgotten solutio…
Source Finding in Linear Polarization for LOFAR, and SKA Predecessor Surveys, using Faraday Moments
J. S. Farnes, G. Heald, H. Junklewitz +10
The optimal source-finding strategy for linear polarization data is an unsolved problem, with many inhibitive factors imposed by the technically-challenging nature of polarization…
The challenges of low-frequency radio polarimetry: lessons from the Murchison Widefield Array
Emil Lenc, C. S. Anderson, N. Barry +26
We present techniques developed to calibrate and correct Murchison Widefield Array (MWA) low frequency (72-300 MHz) radio observations for polarimetry. The extremely wide field-of-…
A polarized fast radio burst at low Galactic latitude
E. Petroff, S. Burke-Spolaor, E. F. Keane +35
We report on the discovery of a new fast radio burst, FRB 150215, with the Parkes radio telescope on 2015 February 15. The burst was detected in real time with a dispersion measure…
Broadband, radio spectro-polarimetric study of 100 radiative-mode and jet-mode AGN
S. P. O'Sullivan, C. R. Purcell, C. S. Anderson +3
We present the results from a broadband (1 to 3 GHz), spectro-polarimetry study of the integrated emission from 100 extragalactic radio sources with the ATCA, selected to be highly…
LOFAR MSSS: Discovery of a 2.56 Mpc giant radio galaxy associated with a disturbed galaxy group
A. O. Clarke, G. Heald, T. Jarrett +40
We report on the discovery in the LOFAR Multifrequency Snapshot Sky Survey (MSSS) of a giant radio galaxy (GRG) with a projected size of Mpc projected on the sky. I…
