Quantifying ionospheric effects on time-domain astrophysics with the Murchison Widefield Array
Shyeh Tjing Loi, Tara Murphy, Martin E. Bell +39
Refraction and diffraction of incoming radio waves by the ionosphere induce time variability in the angular positions, peak amplitudes and shapes of radio sources, potentially comp…
Broadband Spectral Modeling of the Extreme Gigahertz-Peaked Spectrum Radio Source PKS B0008-421
J. R. Callingham, B. M. Gaensler, R. D. Ekers +40
We present broadband observations and spectral modeling of PKS B0008-421, and identify it as an extreme gigahertz-peaked spectrum (GPS) source. PKS B0008-421 is characterized by th…
GLEAM: The GaLactic and Extragalactic All-sky MWA survey
R. B. Wayth, E. Lenc, M. E. Bell +52
GLEAM, the GaLactic and Extragalactic All-sky MWA survey, is a survey of the entire radio sky south of declination +25 deg at frequencies between 72 and 231 MHz, made with the Murc…
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…
The Murchison Widefield Array Correlator
S. M. Ord, B. Crosse, D. Emrich +64
The Murchison Widefield Array (MWA) is a Square Kilometre Array (SKA) Precursor. The telescope is located at the Murchison Radio--astronomy Observatory (MRO) in Western Australia (…
The High Time and Frequency Resolution Capabilities of the Murchison Widefield Array
S. E. Tremblay, S. M. Ord, N. D. R. Bhat +37
The science cases for incorporating high time resolution capabilities into modern radio telescopes are as numerous as they are compelling. Science targets range from exotic sources…
