The Murchison Widefield Array Commissioning Survey: A Low-Frequency Catalogue of 14,110 Compact Radio Sources over 6,100 Square Degrees
Natasha Hurley-Walker, John Morgan, Randall B. Wayth +49
We present the results of an approximately 6,100 square degree 104--196MHz radio sky survey performed with the Murchison Widefield Array during instrument commissioning between 201…
Suitability of NVIDIA GPUs for SKA1-Low
Alessio Magro, Kristian Zarb Adami, Steve Ord
In this memo we investigate the applicability of NVIDIA Graphics Processing Units (GPUs) for SKA1-Low station and Central Signal Processing (CSP)-level processing. Station-level pr…
Study of Redshifted HI from the Epoch of Reionization with Drift scan
Sourabh Paul, Shiv K. Sethi, Ravi Subrahmanyan +37
The detection of the Epoch of Reionization (EoR) in the redshifted 21-cm line is a challenging task. Here we formulate the detection of the EoR signal using the drift scan strategy…
WSClean: an implementation of a fast, generic wide-field imager for radio astronomy
A. R. Offringa, B. McKinley, N. Hurley-Walker +50
Astronomical widefield imaging of interferometric radio data is computationally expensive, especially for the large data volumes created by modern non-coplanar many-element arrays.…
Observing the Sun with the Murchison Widefield Array
D. Oberoi, R. Sharma, S. Bhatnagar +42
The Sun has remained a difficult source to image for radio telescopes, especially at the low radio frequencies. Its morphologically complex emission features span a large range of…
