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…

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…

Neutral hydrogen (HI) gas content of galaxies at

Jonghwan Rhee, Philip Lah, Frank H. Briggs +5

We use observations made with the Giant Metrewave Radio Telescope (GMRT) to probe the neutral hydrogen (HI) gas content of field galaxies in the VIMOS VLT Deep Survey (VVDS) 14h fi…

Spectral energy distribution and radio halo of NGC 253 at low radio frequencies

A. D. Kapinska, L. Staveley-Smith, R. Crocker +67

We present new radio continuum observations of NGC253 from the Murchison Widefield Array at frequencies between 76 and 227 MHz. We model the broadband radio spectral energy distrib…

A Matched Filter Technique For Slow Radio Transient Detection And First Demonstration With The Murchison Widefield Array

L. Feng, R. Vaulin, J. N. Hewitt +30

Many astronomical sources produce transient phenomena at radio frequencies, but the transient sky at low frequencies (<300 MHz) remains relatively unexplored. Blind surveys with ne…

Delay Spectrum with Phase-Tracking Arrays: Extracting the HI power spectrum from the Epoch of Reionization

Sourabh Paul, Shiv K. Sethi, Miguel F. Morales +51

The Detection of redshifted 21 cm emission from the epoch of reionization (EoR) is a challenging task owing to strong foregrounds that dominate the signal. In this paper, we propos…
