    Our goal is to determine which 100 nm wide wavelength region provides the most precise radial velocities between 800 and 2500 nm. For this reason, we generated 20,000 spectra with random Teff, logg, and [M/H] values at a resolution of 10,000, shifted their spectra by a random radial velocity between -100 and 100 km/s. Each spectrum was assigned a random SNR between 10 and 100 with a Gaussian...

    DZA, the Deutsches Zentrum für Astrophysik, is an emerging national research center for astrophysics that is current being established in the city of Görlitz in East Germany. Over a startup period of 15 years, the center is expected to establish critical mass in the areas of fundamental research, big data, and technology development, with the goal to better enable German astronomers to engage...
