Erik Zackrisson

Erik Zackrisson is a Professor in the Department of Physics and Astronomy at Uppsala University, specializing in Astronomy and Space Physics. His research primarily focuses on the early universe, including the formation of the first stars, galaxies, and black holes, utilizing advanced observational techniques and the James Webb Space Telescope.

Professor Zackrisson's research interests span several key areas of modern astrophysics:

• Early universe cosmology and the epoch of reionization
• Gravitational lensing as a tool for studying distant celestial objects
• Search for extraterrestrial intelligence through anomalous stellar signatures
• Application of machine learning techniques to astronomical data analysis
• Population III stars and the first generation of cosmic structures

His recent publications demonstrate a strong focus on JWST observations, with numerous papers analyzing gravitationally lensed objects at extreme redshifts. His work spans observational astronomy, theoretical modeling, and innovative applications like the search for Dyson spheres. The research shows consistent collaboration with international teams across multiple major observatories and space missions.

Professor Zackrisson leads Project Hephaistos, which investigates potential Dyson sphere signatures in stellar data from missions like Gaia, 2MASS, and WISE. His work on the first stars and galaxies has been widely recognized, with multiple publications in top-tier journals including Nature and Nature Astronomy.
