About
Engin Keles is an instrumental astronomer whose work has significantly advanced high-resolution stellar spectroscopy and polarimetry. As a key figure behind the Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) on the Large Binocular Telescope (LBT), Keles has enabled transformative studies of stellar magnetic fields, exoplanet host stars, and chemical abundances. His most-cited paper details PEPSI’s performance, showcasing its ability to cover the full optical spectrum (384–913 nm) at resolutions up to R=250,000—among the highest for any ground-based spectrograph. This instrument has become a cornerstone for precision radial velocity measurements and magnetic activity monitoring, directly impacting exoplanet detection and stellar astrophysics. With over 8 citations on this foundational work alone, Keles’s contributions have been instrumental in pushing the boundaries of observational astrophysics. His expertise in fiber-fed, stabilized spectrograph design and polarimetric techniques has made PEPSI a benchmark facility, enabling researchers worldwide to probe the magnetic lives of stars and the atmospheres of distant worlds. For students and researchers, Keles exemplifies how cutting-edge instrumentation drives discovery in modern astronomy.
