Multifrequency, Multiresolution Image Detection
The next decade will mark the start of a new era in multi-frequency astronomy. New surveys and satellites are coming on line that will open up the full electromagnetic spectra at higher precision and to fainter flux levels than ever before (from X-rays through to the submillimeter and radio). Together these multi-frequency surveys will provide a bolometric view of the Universe from which we might fully reconstruct the properties of Galactic and extra-galactic sources. Studying these data sets in isolation will provide some insight into the processes that drive the evolution of our Universe. It is only, however, if we analyze the multi-frequency data in unison that we might fully exploit their scientific potential. We have, therefore, developed a new and novel technique for combining multi-frequency data that provides objective source detection. We propose here to develop these algorithms into a suite of software tools that will enable the astronomical community to explore multi-frequency, multi-resolution data in an optimal fashion.
