Title: A novel method for image reconstruction with radio interferometers
Date: Thursday, March 6th, 2014
Time: 11:30
Venue: Villa Bazzoni
***********************************************************
Abstract I will present a new, general-purpose method for
reconstructing images from radio interferometric observations using
the Bayesian method of Gibbs sampling. The method automatically takes
into account incomplete coverage and mode coupling. Using a set of
mock images with realistic observing scenarios I will show that this
approach performs better than traditional methods. In addition, Gibbs
sampling scales well and provides complete statistical information. I
will discuss the application of this method to upcoming 21-cm and CMB
polarization experiments.
