Career and research
Högbom is most well known for the development of the CLEAN algorithm for deconvolution of images created in radio astronomy, published in 1974. This allows the use of arrays of small antennae, generating incomplete sampling data, to effectively simulate a much larger aperture. Högbom was also the first to use Earth rotation synthesis imaging in a small test.
These methods pioneered by Högbom are still extensively used and combined, e.g. in the imaging of the central supermassive black hole of the Messier 87 galaxy.
