Hunting for radio emission from the intermittent pulsar J1107-5907 at low frequencies
B. W. Meyers, S. E. Tremblay, N. D. R. Bhat +30
The rare intermittent pulsars pose some of the most challenging questions surrounding the pulsar emission mechanism, but typically have relatively minimal low-frequency (…
In situ measurement of MWA primary beam variation using ORBCOMM
J. L. B. Line, B. McKinley, J. Rasti +21
We provide the first in situ measurements of antenna element (tile) beam shapes of the Murchison Widefield Array (MWA), a low radio-frequency interferometer and an SKA precursor. M…
Observations of Low-Frequency Radio Emission from Millisecond Pulsars and Multipath Propagation in the Interstellar Medium
N. D. R. Bhat, S. E. Tremblay, F. Kirsten +23
Studying the gravitational-wave sky with pulsar timing arrays (PTAs) is a key science goal for the Square Kilometre Array (SKA) and its pathfinder telescopes. With current PTAs rea…
Comparing Redundant and Sky Model Based Interferometric Calibration: A First Look with Phase II of the MWA
W. Li, J. C. Pober, B. J. Hazelton +53
Interferometric arrays seeking to measure the 21 cm signal from the Epoch of Reionization must contend with overwhelmingly bright emission from foreground sources. Accurate recover…
Galactic synchrotron distribution derived from 152 HII region absorption features in the full GLEAM survey
H. Su, J. P. Macquart, N. Hurley-Walker +22
We derive the synchrotron distribution in the Milky Way disk from HII region absorption observations over -40° < l < 40° at six frequencies of 76.2, 83.8, 91.5, 99.2, 106.9, and 11…
Limits on radio emission from meteors using the MWA
Xiang Zhang, Paul Hancock, Hadrien A. R. Devillepoix +20
Recently, low frequency, broadband radio emission has been observed accompanying bright meteors by the Long Wavelength Array (LWA). The broadband spectra between 20 and 60 MHz were…
