The swept-back multipolar magnetic field of neutron stars: Application to NICER MSP J0030+0451

Anu Kundu, Constantinos Kalapotharakos, Zorawar Wadiasingh +5

NICER observations of millisecond pulsars (MSPs) suggest that non-dipolar magnetic fields are required to explain their surface X-ray hotspots. C. Kalapotharakos et al. (2021) mode…

On the Expected Orbitally-modulated TeV Signatures of Spider Binaries: The Effect of Intrabinary Shock Geometry

Christo Venter, Andreas Kopp, Zorawar Wadiasingh +2

'Spider' binary systems - black widow and redback compact binaries differentiated by their companion's mass and nature - are an important type of pulsar system exhibiting a rich em…

Towards Modelling AR Sco: Calibration -- Reproducing High-Energy Pulsar Emission and Testing Convergence to Aristotelian Electrodynamics

Louis Du Plessis, Christo Venter, Alice K. Harding +2

In recent years, kinetic simulations have been crucial to further our understanding of pulsar electrodynamics. Yet, due to the large-scale separation between the gyro-period vs the…

Radio pulsations from the -ray millisecond pulsar PSR J2039-5617

A. Corongiu, R. P. Mignani, A. S. Seyffert +9

The predicted nature of the candidate redback pulsar 3FGL\,J2039.65618 was recently confirmed by the discovery of -ray millisecond pulsations (Clark et al. 2020, hereafter Pa…

Probing the pulsar population of Terzan 5 via spectral modeling

Hambeleleni Ndiyavala, Christo Venter, Tyrel J. Johnson +5

Terzan 5 is the only Galactic globular cluster that has plausibly been detected at very-high energies by the High Energy Stereoscopic System. It has an unexpectedly asymmetric very…

Pulsar emission in the very-high-energy regime

M. Breed, C. Venter, A. K. Harding

The vast majority of the pulsars detected by the Fermi Large Area Telescope (LAT) display spectra with exponential cutoffs falling in a narrow range around a few GeV. Early spectra…
