Multi-wavelength observations of PSR B1259-63 during the 2014 periastron passage
Abstract
The gamma-ray binary star system PSR B1259-63 is unique among the five known systems since it is the only one where a radio pulsar has been directly detected. Close to periastron the system produces non-thermal/unpulsed emission from radio to TeV gamma-ray energies. In 2010 Fermi/LAT detected a rapid increase and peak emission at ∼30 days after periastron, at a time when emission at other wavelengths was already decreasing. PSR B1259-63 will go through periastron again on 2014 May 4. We have proposed to use the Southern African Large Telescope and the KAT-7 radio telescope array in order to contribute to the multi-wavelength coverage of the system. An outline of this proposed multi-wavelength campaign is presented.
