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…
