The discovery of persistent radio sources (PRSs) associated with repeating fast radio bursts (FRBs) has shed light on the immediate environments and possible progenitors of these F…
Search for persistent radio emission towards selected localised Fast Radio Burst positions using the MeerKAT Telescope
Thulo Letsele, Lebogang Mfulwane, Christo Venter +2
Fast Radio Bursts (FRBs) are millisecond-duration radio pulses originating from cosmological distances, as indicated by their large dispersion measures. While numerous FRBs have no…

We present the discovery of 30 new Galactic sources from the MeerTRAP project, a commensal fast radio transient search programme using the MeerKAT telescope. These sources were all…
A fast radio burst from the first 3 billion years of the Universe
Manisha Caleb, Themiya Nanayakkara, Benjamin Stappers +25
Fast radio bursts (FRBs) are enigmatic millisecond-duration signals which encode otherwise unattainable information on the plasma which permeates our Universe, providing insights i…
MeerKAT discovery of a hyperactive repeating fast radio burst source

Slow and steady: long-term evolution of the 76-second pulsar J09014046
M. C. Bezuidenhout, N. D. R. Bhat, M. Caleb +10
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 coherent radio burst from an X-ray neutron star in the Carina Nebula
K. M. Rajwade, J. Tian, G. Younes +10
The neutron star zoo comprises several sub-populations that range from energetic magnetars and thermally emitting X-ray neutron stars to radio-emitting pulsars. Despite studies ove…
Contemporaneous optical-radio observations of a fast radio burst in a close galaxy pair
K. Y. Hanmer, I. Pastor-Marazuela, J. Brink +20
We present the MeerKAT discovery and MeerLICHT contemporaneous optical observations of the Fast Radio Burst (FRB) 20230808F, which was found to have a dispersion measure of $\mathr…
Discovery of 26 new Galactic radio transients by MeerTRAP
James Dennis Turner, Ben W. Stappers, Jun Tian +10
Radio searches for single pulses provide the opportunity to discover one-off events, fast transients and some pulsars that might otherwise be missed by conventional periodicity sea…
Timing analysis of rotating radio transients discovered with MeerKAT
Thulo Letsele, Mechiel Christiaan Bezuidenhout, the MeerTRAP collaboration
Pulsars are rapidly rotating neutron stars that emit pulses of radiation at regular intervals, typically ranging from milliseconds to seconds. The precise recording and modelling o…
Detection and localisation of the highly active FRB 20240114A with MeerKAT
J. Tian, K. M. Rajwade, I. Pastor-Marazuela +6
We report observations of the highly active FRB 20240114A with MeerKAT using the Ultra-High Frequency (UHF; MHz) and L-band ( MHz) receivers. A…
A study of two FRBs with low polarization fractions localized with the MeerTRAP transient buffer system
K. M. Rajwade, L. N. Driessen, E. D. Barr +19
Localisation of fast radio bursts (FRBs) to arcsecond and sub-arcsecond precision maximizes their potential as cosmological probes. To that end, FRB detection instruments are deplo…
FRB 20121102A: images of the bursts and the varying radio counterpart
L. Rhodes, M. Caleb, B. W. Stappers +4
As more Fast Radio Bursts (FRBs) are being localised, we are learning that some fraction have persistent radio sources (PRSs). Such a discovery motivates an improvement in our unde…
Discovery of an Extremely Intermittent Periodic Radio Source
M. P. Surnis, K. M. Rajwade, B. W. Stappers +12
We report the serendipitous discovery of an extremely intermittent radio pulsar, PSR J1710-3452, with a relatively long spin period of 10.4 s. The object was discovered through the…
