When it rains…

April 10, 2025

The image above was taken on the last weekend in March after around 120mm of rain fell in the area over two days. The event led to widespread flooding locally, […]

Reflecting on the ATCA’s future

April 9, 2025

The Australia Telescope User Committee is meeting this week, and an ATCA Science Day was held yesterday to explore new opportunities and highlight ATCA’s unique capabilities in the SKA era. […]

Unusual Intraburst Variations of Polarization States in FRB 20210912A and FRB 20230708A: Effects of Plasma Birefringence?

April 8, 2025

Fast radio bursts (FRBs) are highly energetic events of short-duration intense radio emission, the origin of which remains elusive. Polarization of the FRB signals carries information about the emission source […]

Exploring Unusual High-frequency Eclipses in MSP J1908+2105

April 7, 2025

This paper presents a comprehensive study of the eclipse properties of the spider millisecond pulsar (MSP) J1908+2105, using wide-band observations from the uGMRT and Parkes UWL. For the first time, […]

A depolarisation census of ASKAP fast radio bursts

April 4, 2025

Fast radio bursts (FRBs) are luminous, dispersed pulses of extra-galactic origin. The physics of the emission mechanism, the progenitor environment, and their origin are unclear. Some repeating FRBs are observed […]

Relighting the fire in Hickson Compact Group (HCG) 15: magnetised fossil plasma revealed by the SKA Pathfinders & Precursors

April 3, 2025

In the context of the life cycle and evolution of active galactic nuclei (AGN), the environment plays an important role. In particular, the over-dense environments of galaxy groups, where dynamical […]

Revealing the Ghosts of the Radio Universe: Faint Cosmic Circles Uncovered by ASKAP and MeerKAT

April 2, 2025

Astronomers have uncovered a hidden realm of faint, circular cosmic structures—dubbed the “ghosts of the radio universe”—using powerful new radio telescopes like ASKAP in Australia and MeerKAT in South Africa. […]

The Emission Geometry of Pulsars with Interpulses

April 1, 2025

Sun et al. present polarisation profiles of 23 pulsars exhibiting interpulse (IP) emissions using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST). By applying the rotating vector model (RVM), the inclination […]

Enhanced Astrometry of the Rapid ASKAP Continuum Survey for Precise Localisation of Fast Radio Bursts

March 31, 2025

Fast Radio Bursts (FRBs) are short, intense radio signals from distant astrophysical sources, and their accurate localisation is crucial for probing their origins and utilising them as cosmological tools. This […]

Square Kilometre Array Science Data Challenge 3a: Foreground Removal for an EoR Experiment

March 28, 2025

Bonaldi et al. present and analyse the results of the Science Data Challenge 3a (SDC3a), a community-wide exercise on foreground removal for Epoch of Reionisation (EoR) experiments, organised by the […]

Discovery and Timing of Four γ-ray Millisecond Pulsars

March 27, 2025

Kerr et al. report the discovery of four millisecond pulsars (MSPs) found in searches of 80 γ-ray sources conducted between 2015 and 2017 using the Murriyang radio telescope at the […]

Exploring a tentative link between FRBs and pulsars with broad energy distributions and applications for nearby FRB survey strategies

March 26, 2025

Fast radio bursts (FRBs) are brief but powerful flashes of radio waves whose origins remain largely mysterious. In this study, Zhang et al. investigate the FRBs and pulsars with broad […]
