Research projects

The Galaxy Mapper Instrument at Calar Alto (GAMAICA) is a proposed integral field spectrograph for the 3.5 m telescope of the Centro Astronomico Hispano-Aleman (CAHA) on Calar Alto.

ANDES (formerly called HIRES) is the high-resolution spectrograph for the ELT.

Potsdam Echelle Polarimetric and Spectroscopic Instrument for the LBT, high-resolution polarimetric spectrograph

BlueMUSE will be a blue-optimized version of the MUSE integral field spectrograph.

PEPSI during daytime: disk-unresolved solar light is fed to the spectrograph from a small Sun-as-a-star telescope. The upgrade SDI-POL will feed polarised light via two fibers to the spectrograph.

The PEPSI Exoplanet Transit Survey is a key science project of the PEPSI spectrograph and investigates the atmospheres of exoplanets, from super-Earths to Hot Jupiters.

A high-resolution survey of TESS target stars near the northern ecliptic pole.

4-meter Multi Object Spectroscopic Telescope

A multi-object spectrograph for the ESO ELT in Chile.

An integral-field spektrograph for the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX)

Solar Disk Integrated (SDI) telescope to feed disk-unresolved solar light to the PEPSI spectrograph.

The integral-field spectrograph at the European Very Large Telescope in Chile.

Robotic telescopes for stellar activity. Instruments are an Echelle spectrograph and a wide-field imaging photometer.

The Potsdam Multi-Aperture Spectrophotometer at Calar Alto.

The Large Binocular Telescope on Mt. Graham in Arizona is equipped with two 8.4-metre-diameter mirrors mounted in parallel like binoculars.
