A contingent from South Africa's RATT group

Submitter:	Griffin Foster
Description:	Since May, four members of the Radio Astronomy Techniques and Technologies group() of Rhodes University (South Africa) have been based at ASTRON(), working on various projects related to calibration, modeling, and simulation. Dr Trienko Grobler (Rhodes, SKA-SA) has developed the mathematical framework to describe the infamous 'ghost' sources in WSRT images. Sphesihle Makhathini (Rhodes) has developed a number of simulations which are being used to help define the SKA1-mid antenna layout. Iniyan Natarajan (UCT) is working on a Bayesian approach to interferometric calibration, and involved with the development of the generalized aw-imager* Dr Griffin Foster (Rhodes, SKA-SA) has been working to develop a polarization calibration method for low-frequency elements such as the LBA, HBA, and PAPER dipoles. Today, three of them will offer brief presentations about their work at a special edition of the TechnoLunch (12:30, Hooghoudt Room).

This exchange has been part of the MIDPREP collaboration between South Africa, ASTRON, and Chalmers University (Sweden). () The Centre for Radio Astronomy Techniques and Technologies (RATT) is based around the SKA Research Chair of prof Oleg Smirnov (Rhodes University, South Africa).* () Distance makes the heart grow fonder. Both sides greatly value the special relationship.
