An overview of the study of imprecatory Psalms: reformed and evangelical approaches to the interpretation of imprecatory Psalms
Simango, Daniel; Krüger, P. Paul (The Old Testament Society of Southern Africa (OTSSA), 2016)This article looks at some interpretive issues regarding the so-called imprecatory psalms, focusing on the debate within reformed and evangelical circles. Introductory issues regarding these psalms abound, such as their ... -
Cheap 0.36 dB broadband multipath LNA
Krüger, Petrus Paulus (Institution of Engineering and Technology (IET), 2012)A two-path low-noise amplifier (LNA) designed for the planned MeerKAT radio telescope is presented. The LNA has a noise figure (NF) of less than 0.36 dB and input return loss of less than 12 dB from 0.7 to 1.8 GHz. It ... -
HESS and Fermi-LAT discovery of γ-rays from the blazar 1ES 1312-423
Abramowski, A.; Casanova, S.; Krüger, P.P.; Pekeur, N.W.; Sushch, I.; Venter, C.; Vorster, M.; H.E.S.S. Collaboration (Oxford Univ Press, 2013)A deep observation campaign carried out by the High Energy Stereoscopic System (HESS) on Centaurus A enabled the discovery of γ-rays from the blazar 1ES 1312−423, 2° away from the radio galaxy. With a differential flux at ... -
HESS J1640-465: an exceptionally luminous TeV γ-ray supernova remnant
Abramowski, A.; Casanova, S.; Davids, I.D.; Krüger, P.P.; Pekeur, N.W.; Sushch, I.; Venter, C.; Vorster, M.; Böttcher, M.; H.E.S.S. Collaboration (Oxford Univ Press, 2014)The results of follow-up observations of the TeV γ-ray source HESS J1640−465 from 2004 to 2011 with the High Energy Stereoscopic System (HESS) are reported in this work. The spectrum is well described by an exponential ... -
'Het u net een seën?': Vrede as oorvloeiseën as tema in Genesis 12-50
Krüger, Paul (AOSIS, 2016)Have you but one blessing?': Peace as overflow of blessings in Genesis 12-50. A theme often overlooked in the patriarchal history (Gn 12-50) is the blessings bestowed on individuals outside the covenantal lineage, for ... -
Impact of aerosols and adverse atmospheric conditions on the data quality for spectral analysis of the H.E.S.S. telescopes
Hahn, J.; Krüger, P.; De los Reyes, R.; Bernlöhr, K.; Lo, Y.T.E. (Elsevier, 2014)The Earth’s atmosphere is an integral part of the detector in ground-based imaging atmospheric Cherenkov telescope (IACT) experiments and has to be taken into account in the calibration. Atmospheric and hardware-related ... -
Long-term TeV and X-ray observations of the gamma-ray binary HESS J0632+057
Abramowski, A.; Böttcher, M.; Casanova, S.; Krüger, P.P.; Pekeur, N.W.; Sushch, I.; Venter, C.; Vorster, M.; H.E.S.S. Collaboration (IOP Publishing, 2014)HESS J0632+057 is the only gamma-ray binary known so far whose position in the sky allows observations with ground-based observatories in both the northern and southern hemispheres. Here we report on long-term observations ... -
TeV γ-ray observations of the young synchrotron-dominated SNRs G1.9+0.3 and G330.2+1.0 with H.E.S.S.
Abramowski, A.; Böttcher, M.; Casanova, S.; Davids, I.D.; Krüger, P.P.; Pekeur, N.W.; Sushch, I.; Venter, C.; Vorster, M.; H.E.S.S. Collaboration (Oxford Univ Press, 2014)The nonthermal nature of the Xray emission from the shelltype supernova remnants (SNRs) G1.9+0.3 and G330.2+1.0 is an indication of intense particle acceleration in the shock fronts of both objects. This suggests that ...
