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.[2][3] 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.[1][4][5]
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.[6][7]
Awards and honours
Högbom was elected member of the Royal Swedish Academy of Sciences in 1981.[8]
