Understanding Pulsar Magnetospheres with the SKAO
L. S. Oswald, A. Basu, M. Chakraborty +21
The SKA telescopes will bring unparalleled sensitivity across a broad radio band, a wide field of view across the Southern sky, and the capacity for sub-arraying, all of which make…
The Astrophysics of Fast Radio Bursts
Alice P. Curtin, Marcin Gawroński, Jason Hessels +11
Fast radio bursts (FRBs) provide a glimpse of high-energy astrophysical phenomena in other galaxies. They point the way to extreme conditions that are currently undetectable by any…

Pulsar B1237+25 Aberration/Retardation Analysis from Decimeter to Decameter Wavelength: Challenge to "Radius-to-Frequency Mapping"
Joanna M. Rankin, Vyacheslav Zakharenko, Oleg Ulyanov +9
PSR B1237+25 is perhaps the canonical example of a pulsar with a core/double cone profile. Moreover, it is bright with little spectral turnover, and its profile perhaps uniquely re…
Discovery of 30 Galactic radio transient pulsars with MeerTRAP

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…
Localisation and host galaxy identification of new Fast Radio Bursts with MeerKAT
Inés Pastor-Marazuela, Alexa C. Gordon, Ben Stappers +18
Accurately localising fast radio bursts (FRBs) is essential for understanding their birth environments and for their use as cosmological probes. Recent advances in radio interferom…
MeerKAT discovery of a hyperactive repeating fast radio burst source
J. Tian, I. Pastor-Marazuela, K. M. Rajwade +17
We present the discovery and localisation of a repeating fast radio burst (FRB) source from the MeerTRAP project, a commensal fast radio transient search programme using the MeerKA…
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…
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…
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…
The Third Fermi Large Area Telescope Catalog of Gamma-ray Pulsars
David A. Smith, Philippe Bruel, Colin J. Clark +156
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio…
Discovery of an Extremely Intermittent Periodic Radio Source
