    • Bayesian inference for radio observations 

      Lochner, Michelle; Oozeer, Nadeem; Natarajan, Iniyan; Zwart, Jonathan T.L.; Smirnov, Oleg; Bassett, Bruce A. (Oxford University Press, 2015)
      New telescopes like the Square Kilometre Array (SKA) will push into a new sensitivity regime and expose systematics, such as direction-dependent effects, that could previously be ignored. Current methods for handling such ...
    • Broad-band reflection spectroscopy of MAXI J1535-571 using AstroSat: estimation of black hole mass and spin 

      Sridhar, Navin; Chandra, Sunil; Bhattacharyya, Sudip; Antia, H.M. (Oxford Univ Press, 2019)
      We report the results from AstroSat observations of the transient Galactic black hole X-ray binary MAXI J1535–571 during its hard-intermediate state of the 2017 outburst. We systematically study the individual and joint ...
    • A polarized fast radio burst at low Galactic latitude 

      Petroff, E.; Abdalla, H.; Barnard, M.; Böttcher, M.; Davids, I.D.; Garrigoux, T.; Ivascenko, A.; Krüger, P.P.; Pekeur, N.W.; Seyffert, A.S.; Spanier, F.; Sushch, I.; Van der Walt, D.J.; Van Rensburg, C.; Venter, C.; Wadiasingh, Z.; H.E.S.S. Collaboration (Oxford Univ Press, 2017)
      We report on the discovery of a new fast radio burst (FRB), FRB 150215, with the Parkes radio telescope on 2015 February 15. The burst was detected in real time with a dispersion measure (DM) of 1105.6 ± 0.8 pc cm−3, a ...
    • Probing the ATIC peak in the cosmic-ray electron spectrum with H.E.S.S. 

      Aharonian, F.; Büsching, I.; Davids, I.D.; De Jager, O.C.; Holleran, M.; Raubenheimer, B.C.; Venter, C.; H.E.S.S. Collaboration (EDP Sciences, 2009)
      The measurement of an excess in the cosmic-ray electron spectrum between 300 and 800 GeV by the ATIC experiment has – together with the PAMELA detection of a rise in the positron fraction up to ≈ 100 GeV – ...
    • Sopie: an R package for the non-parametric estimation of the off-pulse interval of a pulsar light curve 

      Schutte, Willem D.; Swanepoel, Jan W.H. (Oxford Univ Press, 2016)
      An automated tool to derive the off-pulse interval of a light curve originating from a pulsar is needed. First, we derive a powerful and accurate non-parametric sequential estimation technique to estimate the off-pulse ...
    • Spectrum and variability of the Galactic center VHE y-ray source HESS J1745-290 

      Aharonian, F.; Büsching, I.; Davids, I.D.; De Jager, O.C.; Holleran, M.; Raubenheimer, B.C.; Venter, C.; H.E.S.S. Collaboration (EDP Sciences, 2009)
      Aims. A detailed study of the spectrum and variability of the source HESS J1745-290 in the Galactic Center (GC) region using new data from the H.E.S.S. array of Cherenkov telescopes is presented. Flaring activity and quasi ...
