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…
Radio continuum and polarization study of SNR G57.2+0.8 associated with magnetar SGR1935+2154
R. Kothes, X. Sun, B. Gaensler +1
We present a radio continuum and linear polarization study of the Galactic supernova remnant G57.2+0.8, which may host the recently discovered magnetar SGR1935+2154. The radio SNR…
Classifying Complex Faraday Spectra with Convolutional Neural Networks
Shea Brown, Brandon Bergerud, Allison Costa +7
Advances in radio spectro-polarimetry offer the possibility to disentangle complex regions where relativistic and thermal plasmas mix in the interstellar and intergalactic media. R…
When disorder looks like order: a new model to explain radial magnetic fields in young supernova remnants
J. L. West, T. Jaffe, G. Ferrand +2
Radial magnetic fields are observed in all known young, shell-type supernova remnants (SNRs) in our Galaxy, including Cas A, Tycho, Kepler, and SN1006 and yet the nature of these r…
Future Cosmological Constraints from Fast Radio Bursts
Anthony Walters, Amanda Weltman, B. M. Gaensler +2
We consider the possible observation of Fast Radio Bursts (FRBs) with planned future radio telescopes, and investigate how well the dispersions and redshifts of these signals might…
Calibration and Stokes Imaging with Full Embedded Element Primary Beam Model for the Murchison Widefield Array
M. Sokolowski, T. Colegate, A. T. Sutinjo +22
The Murchison Widefield Array (MWA), located in Western Australia, is one of the low-frequency precursors of the international Square Kilometre Array (SKA) project. In addition to…
