wsclean: an implementation of a fast, generic wide-field imager for radio astronomy
Astronomical widefield imaging of interferometric radio data is computationally expensive, especially for the large data volumes created by modern non-coplanar many-element arrays. We present a new
The Murchison Widefield Array: The Square Kilometre Array Precursor at Low Radio Frequencies
Abstract The Murchison Widefield Array (MWA) is one of three Square Kilometre Array Precursor telescopes and is located at the Murchison Radio-astronomy Observatory in the Murchison Shire of the
Upper bounds on the low-frequency stochastic gravitational wave background from pulsar timing observations: current limits and future prospects
Using a statistically rigorous analysis method, we place limits on the existence of an isotropic stochastic gravitational wave background using pulsar timing observations. We consider backgrounds
The Mass of a Millisecond Pulsar
We report on nearly 2 years of timing observations of the low-mass binary millisecond pulsar PSR J1909-3744 with the Caltech-Parkes-Swinburne Recorder II, a new instrument that gives unprecedented
High‐precision baseband timing of 15 millisecond pulsars
We describe extremely precise timing experiments performed on five solitary and 10 binary millisecond pulsars during the past 3 yr, with the Caltech Parkes Swinburne Recorder (CPSR2) coherent
The Murchison Widefield Array: Design Overview
The Murchison Widefield Array is a dipole-based aperture array synthesis telescope designed to operate in the 80-300 MHz frequency range. It is capable of a wide range of science investigations but
GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey - I. A low-frequency extragalactic catalogue
Using the Murchison Widefield Array (MWA), the low-frequency Square Kilometre Array precursor located in Western Australia, we have completed the GaLactic and Extragalactic All-sky MWA (GLEAM) survey
Self-consistency of Relativistic Observables with General Relativity in the White Dwarf-Neutron Star Binary PSR J1141-6545
Here we report timing measurements of the relativistic binary PSR J1141-6545 that constrain the component masses and demonstrate that the orbital period derivative b = (-4 ± 1) × 10-13 is consistent
Real-Time Calibration of the Murchison Widefield Array
TLDR
A real-time peeling implementation for next-generation radio interferometers such as the Murchison widefield array (MWA) is investigated, and the algorithm is seen to work in the presence of strong galactic emission and with various ionospheric conditions.
Limits on Fast Radio Bursts and other transient sources at 182 MHz using the Murchison Widefield Array
We present a survey for transient and variable sources, on time-scales from 28 s to ∼1 yr, using the Murchison Widefield Array (MWA) at 182 MHz. Down to a detection threshold of 0.285 Jy, no
