High-energy sources at low radio frequency: the Murchison Widefield Array view of Fermi blazars
M. Giroletti, F. Massaro, R. D'Abrusco +54
Low-frequency radio arrays are opening a new window for the study of the sky, both to study new phenomena and to better characterize known source classes. Being flat-spectrum sourc…
Strong field tests of gravity with PSR J1141-6545
V. Venkatraman Krishnan, W. van Straten, P. A. Rosado +4
The initial results from timing observations of PSR J1141-6545, a relativistic pulsar white-dwarf binary system, are presented. Predictions from the timing baseline hint at the mos…
A Fast Radio Burst with frequency-dependent polarization detected during Breakthrough Listen observations
D. C. Price, G. Foster, M. Geyer +30
Here, we report on the detection and verification of Fast Radio Burst FRB 180301, which occurred on UTC 2018 March 1 during the Breakthrough Listen observations with the Parkes tel…
Fast Transients at Cosmological Distances with the SKA
J. -P. Macquart, E. Keane, K. Grainge +14
Impulsive radio bursts that are detectable across cosmological distances constitute extremely powerful probes of the ionized Inter-Galactic Medium (IGM), intergalactic magnetic fie…
Pulsar Timing with the Parkes Radio Telescope for the Fermi Mission
P. Weltevrede, S. Johnston, R. N. Manchester +10
We report here on two years of timing of 168 pulsars using the Parkes radio telescope. The vast majority of these pulsars have spin-down luminosities in excess of 10^34 erg/s and a…
Ionospheric modelling using GPS to calibrate the MWA. 1: Comparison of first order ionospheric effects between GPS models and MWA observations
B. S. Arora, J. Morgan, S. M. Ord +56
We compare first order (refractive) ionospheric effects seen by the Murchison Widefield Array (MWA) with the ionosphere as inferred from Global Positioning System (GPS) data. The f…
