Significant new opportunities for astrophysics and cosmology have been identified at low radio frequencies. The Murchison Widefield Array is the first telescope in the Southern Hemisphere designed specifically to explore the low-frequency astronomical sky between 80 and 300 MHz with arcminute angular resolution and high survey efficiency. The telescope will enable new advances along four key science themes, including searching for redshifted 21 cm emission from the epoch of reionisation in the early Universe; Galactic and extragalactic all-sky southern hemisphere surveys; time-domain astrophysics; and solar, heliospheric, and ionospheric science and space weather. The Murchison Widefield Array is located in Western Australia at the site of the planned Square Kilometre Array (SKA) low-band telescope and is the only low-frequency SKA precursor facility. In this paper, we review the performance properties of the Murchison Widefield Array and describe its primary scientific objectives.

  1. Mitigating residual foregrounds and systematic errors in SKA1-Low AA* EoR observations via Bayesian Gaussian Process Regression

    astro-ph.CO 2026-05 unverdicted novelty 5.0

    Bayesian GPR recovers the 21cm signal within 2σ credible intervals for most k-modes (0.06 to 1.0 h/Mpc) in SKA1-Low simulations that include realistic residual foregrounds and systematics.

  2. Role of SKA in Advancing Remote Measurements of Magnetic Fields of Solar Coronal Mass Ejections

    astro-ph.SR 2026-06 unverdicted novelty 4.0

    SKA's higher sensitivity and bandwidth will enable fuller exploitation of radio methods for measuring CME magnetic fields and improving space weather predictions.

  3. Mitigating gain calibration errors from EoR observations with SKA1-Low AA*

    astro-ph.CO 2025-10 unverdicted novelty 4.0

    Simulations show hybrid foreground mitigation (GPR + PCA combined with avoidance) recovers the HI 21cm signal within 2σ for gain calibration errors ≤1% in SKA1-Low AA* observations over 0.05-0.5 Mpc^{-1} scales.

  4. The Murchison Widefield Array Phase III upgrade: Sensitivity Doubled, Number of Baselines Quadrupled, Flexibility Enhanced, and EoR Observations Optimised

    astro-ph.IM 2026-06 unverdicted novelty 3.0

    MWA Phase III upgrade adds receivers and uses MWAX correlator to support full 256-tile correlation, doubling sensitivity and quadrupling baselines.
