Evidence of Ultra-faint Radio Frequency Interference in Deep 21~cm Epoch of Reionization Power Spectra with the Murchison Widefield Array

Michael J. Wilensky, Miguel F. Morales, Bryna J. Hazelton +7

We present deep upper limits from the 2014 Murchison Widefield Array (MWA) Phase I observing season, with a particular emphasis on identifying the spectral fingerprints of extremel…

First constraints on Helium evolution in using the 8.67GHz hyperfine transition

Cathryn M. Trott, Randall B. Wayth

We present the first constraints on the cross-correlation power spectrum of HeII () signal strength using the redshifted 8.67GHz hyperfine transition between $z=2.9…

Measuring the global 21-cm signal with the MWA-II: improved characterisation of lunar-reflected radio frequency interference

Himanshu Tiwari, Benjamin McKinley, Cathryn M. Trott +1

Radio interferometers can potentially detect the sky-averaged signal from the Cosmic Dawn (CD) and the Epoch of Reionisation (EoR) by studying the Moon as a thermal block to the fo…

Two-Screen Scattering in CRAFT FRBs

Mawson W. Sammons, Adam T. Deller, Marcin Glowacki +7

Temporal broadening is a commonly observed property of fast radio bursts (FRBs), associated with turbulent media which cause radiowave scattering. Similarly to dispersion, scatteri…

Singular spectrum analysis of time series data from low frequency radiometers, with an application to SITARA data

Jishnu N. Thekkeppattu, Cathryn M. Trott, Benjamin McKinley

Understanding the temporal characteristics of data from low frequency radio telescopes is of importance in devising suitable calibration strategies. Application of time series anal…
