    • The effect of different magnetospheric structures on predictions of gamma-ray pulsar light curves 

      Breed, M.; Venter, C.; Harding, A.K.; Johnson, T.J. (SAIP, 2014)
      The second pulsar catalogue of the Fermi Large Area Telescope (LAT) will contain in excess of 100 gamma-ray pulsars. The light curves (LCs) of these pulsars exhibit a variety of shapes, and also different relative phase ...
    • Geometric modelling of radio and γ-ray light curves of 6 Fermi LAT pulsars 

      Seyffert, A.S.; Venter, C.; De Jager, O.C.; Harding, A.K. (Sissa Medialab, 2010)
      The Fermi Large Area Telescope (LAT) has recently reported the detection of pulsed γ-rays from 6 young pulsars (J0631+1036, J0659+1414, J0742−2822, J1420−6048, J1509−5850, and J1718−3825), all exhibiting single-peaked ...
    • High-energy pulsar light curves in an offset polar cap B-field geometry 

      Barnard, M.; Venter, C.; Harding, A.K. (HEASA, 2016)
      The light curves and spectral properties of more than 200 γ -ray pulsars have been measured in unsurpassed detail in the eight years since the launch of the hugely successful Fermi Large Area Telescope (LAT) γ -ray ...
    • Modeling light curves of the phase-aligned gamma-ray millisecond pulsar subclass 

      Venter, C.; Johnson, T.J.; Harding, A.K. (Fermi, 2011)
      The gamma-ray population of millisecond pulsars (MSPs) detected by the Fermi Large Area Telescope (LAT) has been steadily increasing. A number of the more recent detections, including PSR J0034−0534, PSR J1939+2134 ...
    • Modelling the growing population of y-ray millisecond pulsars 

      Venter, C.; Harding, A.K.; Johnson, T.J. (Springer, 2011)
      TheFermiLarge Area Telescope, in collaboration with several groups from the radio community, have had marvellous success at uncovering new γ-ray millisecond pulsars (MSPs). In fact, MSPs now make up a sizable fraction of ...
    • Observations and modeling of gamma-ray millisecond pulsars seen with the Fermi LAT 

      Johnson, T.J.; Venter, C.; Harding, A.K.; Guillemot, L.; Fermi LAT (AIPC, 2011)
      We present a summary of gamma-ray millisecond pulsar (MSP) observations with the Fermi Large Area Telescope. The radio and gamma-ray light curves of these MSPs have been modeled in the framework of the retarded vacuum ...
    • Pulsar emission in the very-high-energy regime 

      Breed, M.; Venter, C.; Harding, A.K. (Sissa Medialab, 2015)
      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 spectral modelling predicted spectral cutoff ...
    • Unraveling the emission geometry of the Fermi millisecond pulsars 

      Venter, C.; Harding, A.K.; Guillemot, L. (Fermi, 2009)
      The nine millisecond pulsars (MSPs) that have now been detected by Fermi-LAT are providing an excellent opportunity to probe the emission geometry of these ancient compact objects. As they are radio-loud, one may use the ...
    • Very-high energy emission from pulsars 

      Breed, M.; Venter, C.; Harding, A.K. (SAIP, 2015)
      The vast majority of pulsars detected by the Fermi Large Area Telescope (LAT) display exponentially cutoff spectra with cutoffs falling in a narrow band around a few GeV. Early spectral modelling predicted spectral cutoffs ...
