TL;DR: The Fraunhofer telescope is designed to sustain the excellent (<08" median) seeing of the site [1, Fig 1] over a FOV of 2 deg 2 utilizing three-element transmissive field corrector optics for optical wavebands as discussed by the authors.

TL;DR: The Wide Field Camera Transit Survey (WFCS) as discussed by the authors is a pioneer program aimed to search for extra-solar planets in the near-infrared. But no planet candidate around M-stars has been found, which enabled us to set an upper limit on the occurrence rate of short period giant planets around M dwarfs in the survey.

Dynamical family properties and dark halo scaling relations of giant elliptical galaxies
TL;DR: In this paper, a uniform dynamical analysis of line-profile shapes for 21 luminous round elliptical galaxies was carried out, and the authors investigated the dynamical family relations of ellipticals: (i) the circular velocity curves (CVCs) of elliptical galaxies are flat to within 10% for R>~0.2R_e.

A multi-instrument focal station for a 2m-class robotic telescope
TL;DR: In this paper, the design of a multi-instrument Nasmyth port for a 2m class telescope, located near Munich, Germany, is presented. And a three-channel optical and infrared camera will be located at this NASmyth focus, together with an IFU spectrograph, a high resolution Echelle spectrogram, and a Shack-Hartmann sensor for instrument alignment.
