Using low-frequency pulsar observations to study the 3-D structure of the Galactic magnetic field
C. Sobey, the LOFAR, MWA collaborations
The Galactic magnetic field (GMF) plays a role in many astrophysical processes and is a significant foreground to cosmological signals, such as the Epoch of Reionization (EoR), but…
Studying Magnetic Fields using Low-frequency Pulsar Observations
C. Sobey, the LOFAR, MWA collaborations
Low-frequency polarisation observations of pulsars, facilitated by next-generation radio telescopes, provide powerful probes of astrophysical plasmas that span many orders of magni…
A Census of Southern Pulsars at 185 MHz
Mengyao Xue, N. D. R. Bhat, S. E. Tremblay +7
The Murchison Widefield Array (MWA), and its recently-developed Voltage Capture System (VCS), facilitates extending the low-frequency range of pulsar observations at high-time and…
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-…
Scattering analysis of LOFAR pulsar observations
Marisa Geyer, Aris Karastergiou, Vladislav I. Kondratiev +8
We measure the effects of interstellar scattering on average pulse profiles from 13 radio pulsars with simple pulse shapes. We use data from the LOFAR High Band Antennas, at freque…
