摘要:Wide-field imaging of the radio sky at milli-arcsec resolution is currently restricted to limited numbers of small fields around known sources, due to the immense computational effort needed to image large fields. With the newly developed “Fast Wide-Field Mapping” algorithm, the computational efficiency is increased by orders of magnitude, making wide-field imaging with VLBI possible routinely. In the future, this method will hopefully help to bring the computational burden in SKA imaging down to a manageable level. This contribution describes the idea and reports on results from first tests.
