PSR J09014046, a likely radio-loud neutron star with a period of 75.88 seconds, challenges conventional models of neutron star radio emission. Here, we showcase results from 46…
A long-period radio transient active for three decades
N. Hurley-Walker, N. Rea, S. J. McSweeney +22
Recently several long-period radio transients have been discovered, with strongly polarised coherent radio pulses appearing on timescales between tens to thousands of seconds [1,2]…

We report observations of the highly active FRB 20240114A with MeerKAT using the Ultra-High Frequency (UHF; MHz) and L-band ( MHz) receivers. A…
An emission state switching radio transient with a 54 minute period
M. Caleb, E. Lenc, D. L. Kaplan +19
Long-period radio transients are an emerging class of extreme astrophysical events of which only three are known. These objects emit highly polarised, coherent pulses of typically…

A Needle in a Cosmic Haystack: A Review of FRB Search Techniques
Kaustubh Rajwade, Joeri van Leeuwen
Ephemeral Fast Radio Bursts (FRBs) must be powered by some of the most energetic processes in the Universe. That makes them highly interesting in their own right and as precise pro…
Rapid spin changes around a magnetar fast radio burst
