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 (…
Fundamental Limitations on the Calibration of Redundant 21 cm Cosmology Instruments and Implications for HERA and the SKA
Ruby Byrne, Miguel F. Morales, Bryna Hazelton +7
Precise instrument calibration is critical to the success of 21 cm Cosmology experiments. Unmitigated errors in calibration contaminate the Epoch of Reionization (EoR) signal, prec…
Understanding the Diversity of 21 cm Cosmology Analyses
Miguel F. Morales, Adam Beardsley, Jonathan Pober +4
21 cm power spectrum observations have the potential to revolutionize our understanding of the Epoch of Reionization and Dark Energy, but require extraordinarily precise data analy…
No low-frequency emission from extremely bright Fast Radio Bursts
M. Sokolowski, N. D. R. Bhat, J. P. Macquart +23
We present the results of a coordinated campaign conducted with the Murchison Widefield Array (MWA) to shadow Fast Radio Bursts (FRBs) detected by the Australian Square Kilometre A…
Assessment of ionospheric activity tolerances for Epoch of Reionisation science with the Murchison Widefield Array
Cathryn M. Trott, C. H. Jordan, S. G. Murray +20
Structure imprinted in foreground extragalactic point sources by ionospheric refraction has the potential to contaminate Epoch of Reionisation (EoR) power spectra of the 21~cm emis…
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…
