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…

First Season MWA EoR Power Spectrum Results at Redshift 7

A. P. Beardsley, B. J. Hazelton, I. S. Sullivan +63

The Murchison Widefield Array (MWA) has collected hundreds of hours of Epoch of Reionization (EoR) data and now faces the challenge of overcoming foreground and systematic contamin…

A High Reliability Survey of Discrete Epoch of Reionization Foreground Sources in the MWA EoR0 Field

P. A. Carroll, J. Line, M. F. Morales +61

Detection of the Epoch of Reionization HI signal requires a precise understanding of the intervening galaxies and AGN, both for instrumental calibration and foreground removal. We…

Parametrising Epoch of Reionization foregrounds: A deep survey of low-frequency point-source spectra with the MWA

A. R. Offringa, C. M. Trott, N. Hurley-Walker +38

Experiments that pursue detection of signals from the Epoch of Reionization (EoR) are relying on spectral smoothness of source spectra at low frequencies. This article empirically…

The LOFAR Multifrequency Snapshot Sky Survey (MSSS) I. Survey description and first results

G. H. Heald, R. F. Pizzo, E. Orrú +147

We present the Multifrequency Snapshot Sky Survey (MSSS), the first northern-sky LOFAR imaging survey. In this introductory paper, we first describe in detail the motivation and de…

Foregrounds in Wide-Field Redshifted 21 cm Power Spectra

Nithyanandan Thyagarajan, Daniel C. Jacobs, Judd D. Bowman +61

Detection of 21~cm emission of HI from the epoch of reionization, at redshifts z>6, is limited primarily by foreground emission. We investigate the signatures of wide-field measure…
