Searches for signatures of ultra-light axion dark matter in polarimetry data of the European Pulsar Timing Array
N. K. Porayko, P. Usynina, J. Terol-Calvo +74
Ultra-light axion-like particles (ALPs) can be a viable solution to the dark matter problem. The scalar field associated with ALPs, coupled to the electromagnetic field, acts as an…
Radio and gamma-ray timing of TRAPUM L-band Fermi pulsar survey discoveries
M. Burgay, L. Nieder, C. J. Clark +18
This paper presents the results of a joint radio and gamma-ray timing campaign on the nine millisecond pulsars (MSPs) discovered as part of the L-band targeted survey of Fermi-LAT…
TRAPUM pulsar and transient search in the Sextans A and B galaxies and discovery of background FRB 20210924D
E. Carli, L. Levin, B. W. Stappers +10
The Small and Large Magellanic Clouds are the only galaxies outside our own in which radio pulsars have been discovered to date. The sensitivity of the MeerKAT radio interferometer…
A 34 Yr Timing Solution of the Redback Millisecond Pulsar Terzan 5A
Alexandra C. Rosenthal, Scott M. Ransom, Kyle A. Corcoran +12
We present a 34-year timing solution of the redback pulsar system Terzan 5A (Ter5A). Ter5A, also known as B174424A or J17482446A, has a 11.56 ms pulse period, a 0.1 sol…
Searching for Pulsars, Magnetars, and Fast Radio Bursts in the Sculptor Galaxy using MeerKAT
H. Hurter, C. Venter, L. Levin +10
The Sculptor Galaxy (NGC 253), located in the Southern Hemisphere, far off the Galactic Plane, has a relatively high star-formation rate of about 7 M yr and hosts…
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…
