The Thousand-Pulsar-Array programme on MeerKAT VII: Polarisation properties of pulsars in the Magellanic Clouds
S. Johnston, A. Parthasarathy, R. A. Main +12
The Magellanic Clouds are the only external galaxies known to host radio pulsars. The dispersion and rotation measures of pulsars in the Clouds can aid in understanding their struc…
Noise analysis in the European Pulsar Timing Array data release 2 and its implications on the gravitational-wave background search
A. Chalumeau, S. Babak, A. Petiteau +49
The European Pulsar Timing Array (EPTA) collaboration has recently released an extended data set for six pulsars (DR2) and reported evidence for a common red noise signal. Here we…
Common-red-signal analysis with 24-yr high-precision timing of the European Pulsar Timing Array: Inferences in the stochastic gravitational-wave background search
S. Chen, R. N. Caballero, Y. J. Guo +49
We present results from the search for a stochastic gravitational-wave background (GWB) as predicted by the theory of General Relativity using six radio millisecond pulsars from th…
FAST early pulsar discoveries: Effelsberg follow-up
M. Cruces, D. J. Champion, D. Li +21
We report the follow-up of 10 pulsars discovered by the Five-hundred-meter Aperture Spherical radio-Telescope (FAST) during its commissioning. The pulsars were discovered at a freq…
Burst properties of the highly active FRB 20201124A using uGMRT
V. R. Marthi, S. Bethapudi, R. A. Main +7
We report the observations of the highly active FRb20201124A with the upgraded Giant Metrewave Radio Telescope at 550-750~MHz. These observations in the incoherent array mode simul…
Scintillation timescale measurement of the highly active FRB20201124A
R. A. Main, G. H. Hilmarsson, V. R. Marthi +5
Scintillation of compact radio sources results from the interference between images caused by multipath propagation, and probes the intervening scattering plasma and the velocities…
Discovery and modelling of broad-scale plasma lensing in black-widow pulsar J20510827
F. X. Lin, R. A. Main, J. P. W. Verbiest +2
We report on an unusually bright observation of PSR J20510827 recorded during a regular monitoring campaign of black-widow pulsar systems with the Effelsberg 100-m telescope. Th…
Polarization properties of FRB 20201124A from detections with the 100-m Effelsberg Radio Telescope
G. H. Hilmarsson, L. G. Spitler, R. A. Main +1
The repeating FRB source, FRB 20201124A, was found to be highly active in March and April 2021. We observed the source with the Effelsberg 100-m radio telescope at 1.36 GHz on 9 Ap…
Profile changes associated with DM events in PSR J1713+0747
Fang Xi Lin, Hsiu-Hsien Lin, Jing Luo +5
Propagation effects in the interstellar medium and intrinsic profile changes can cause variability in the timing of pulsars, which limits the accuracy of fundamental science done v…
An analysis of the time-frequency structure of several bursts from FRB121102 detected with MeerKAT
E. Platts, M. Caleb, B. W. Stappers +11
We present a detailed study of the complex time-frequency structure of a sample of previously reported bursts of FRB 121102 detected with the MeerKAT telescope in September 2019. T…
Kinematics of Crab Giant Pulses
Akanksha Bij, Hsiu-Hsien Lin, Dongzi Li +7
The Crab Pulsar's radio emission is unusual, consisting predominantly of giant pulses, with durations of about a micro-second but structure down to the nano-second level, and brigh…
Interstellar Interferometry: Precise Curvature Measurement from Pulsar Secondary Spectra
Daniel Baker, Walter Brisken, Marten H. van Kerkwijk +4
The parabolic structure of the secondary or conjugate spectra of pulsars is often the result of isolated one-dimensional (or at least highly anisotropic) lenses in the ISM. The cur…
