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 […]

Discovery of 15 New Pulsars at High Galactic Latitudes with FAST

March 25, 2025

Xu et al. report the discovery and timing results of 15 pulsars detected in a high Galactic latitude survey conducted using the Five-hundred-meter Aperture Spherical Telescope (FAST). The survey targeted […]

Beyond the First Image: Simulating SKA-Low’s Future Discoveries

March 24, 2025

While the first SKA-Low image demonstrated what the early working version of the telescope (AA0.5) could observe, simulations now show how its capabilities will expand as more antennas are added. […]

‘Beyond what we’d hoped’: SKA-Low’s First Glimpse of the Universe

March 21, 2025

The SKA Observatory (SKAO) has released the first image from an early working version of the SKA-Low telescope, currently under construction on Wajarri Yamaji Country in Western Australia. Using just […]

A Long-Period Radio Transient Active for Over Three Decades

March 20, 2025

Several long-period radio transients have recently been discovered, with strongly polarised coherent radio pulses appearing on timescales between tens to thousands of seconds1,2. In some cases, the radio pulses have […]
