Abstract: Efficient solution methods for Inverse Problems are required in astronomy for the image postprocessing as well as for the imaging process itself. Typical examples for postprocessing are image deblurring or the determination of physical parameters, e.g. the density of a galaxy, from the recorded images. The focus of the minisymposium will be in particular on Inverse Problems related to Adaptive Optics, a technique for the correction of degraded images caused by turbulences in the atmosphere. The correction process is based on the reconstruction of wavefronts coming from guide stars and involves inversion of data from different wavefront sensors and an atmospheric tomography. The minisymposium will present several new reconstruction approaches.
