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…
The Bias and Uncertainty of Redundant and Sky-Based Calibration under Realistic Sky and Telescope Conditions
Ronniy C. Joseph, Cathryn M. Trott, Randall B. Wayth
The advent of a new generation of low frequency interferometers has opened a direct window into the Epoch of Reionisation (EoR). However, key to a detection of the faint 21-cm sign…
The effect of baseline layouts on the EoR foreground wedge: a semi-analytical approach
Steven G. Murray, Cathryn M. Trott
The 2D power spectrum is a cornerstone of the modern toolkit for analysis of the low-frequency radio interferometric observations of the 21 cm signal arising from the early Univers…
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…
