Spectral Modelling of H.E.S.S.-detected Pulsar Wind Nebulae
Carlo van Rensburg, Christo Venter, Paulus Kruger
In the last decade, ground-based Imaging Atmospheric Cherenkov Telescopes have discovered about 175 very-high-energy (VHE; 100 GeV) gamma-ray sources, with more to follow wit…
Modeling and Maximum Likelihood Fitting of Gamma-Ray and Radio Light Curves of Millisecond Pulsars Detected with Fermi
Tyrel J. Johnson, Alice K. Harding, Christo Venter
Pulsed gamma rays have been detected with the Fermi Large Area Telescope (LAT) from more than 20 millisecond pulsars (MSPs), some of which were discovered in radio observations of…
Very-High-Energy Emission From Pulsars
Alice K. Harding, Christo Venter, Constantinos Kalapotharakos
Air-Cherenkov telescopes have detected pulsations at energies above 50 GeV from a growing number of Fermi pulsars. These include the Crab, Vela, PSR B1706-44 and Geminga, with the…
The effect of an offset polar cap dipolar magnetic field on the modeling of the Vela pulsar's -ray light curves
Monica Barnard, Christo Venter, Alice K. Harding
We performed geometric pulsar light curve modeling using static, retarded vacuum, and offset polar cap (PC) dipole -fields (the latter is characterized by a parameter ), in…
Modelling energy-dependent pulsar light curves due to curvature radiation
Monica Barnard, Christo Venter, Alice K. Harding +1
Pulsars emit pulsed emission across the entire electromagnetic spectrum and their light curve phenomenology is strongly dependent on energy. This is also true for the gamma-ray wav…
Search for persistent radio emission towards selected localised Fast Radio Burst positions using the MeerKAT Telescope
Thulo Letsele, Lebogang Mfulwane, Christo Venter +2
Fast Radio Bursts (FRBs) are millisecond-duration radio pulses originating from cosmological distances, as indicated by their large dispersion measures. While numerous FRBs have no…
