An investigation into the nature of the relativistic compact object in the micro-quasar system LS 5039 : a multi-wavelength study
(University of the Free State, 2007-11-30)
English: LS 5039 is a high mass binary system that shows multi-wavelength broad non-thermal emission. It is also a very high energy gamma-ray emitter, with TeV energy gamma-rays detected by H.E.S.S. (High Energy Stereoscopic ...
AutoCal: A software application for calibrating photometric data
(Academy of Science of South Africa (ASSAf), 2016)
We present a software application for the calibration of stellar magnitudes in the absence of standard stars. It uses an existing algorithm to match stars in the target’s field of view to catalogue entries and computes the ...
Gamma-ray production in the Be-type star-pulsar binary system PSR B1259-63
(University of the Free State, 2012-01-30)
English: The high-mass binary system PSR B1259-63/LS 2883 is one of only six known gamma-ray binaries, and the only one where the compact object is known from the direct observation of a pulsed radio signal to be a 48 ms ...
