Imaging and Deconvolution in Radio Interferometry – David Wilner

Title: Imaging and Deconvolution in Radio Interferometry [Lecture 2/2]

 

Speaker: David Wilner, Harvard-Smithsonian Center for Astrophysics (dwilner at cfa.harvard.edu)

 

Date: 2pm (AEDT) Thursday 26th February 2015

 

Abstract: Observations with a typical radio interferometer provide incomplete and noisy samples of the Fourier transform of the sky brightness image that we’d like to analyze. This lecture will provide a pedagogical and practical introduction to the process by which radio interferometric images are made, including visibility weighting and tapering schemes and algorithm-based deconvolution methods to deal with inevitable missing samples. We will conclude with a brief discussion of the Atacama Large Millimeter Array, an new radio interferometer with unprecedented imaging capabilities at millimeter wavelengths.
