The Calibration of the Advanced Stokes Polarimeter
We describe and apply the methods that have been developed to calibrate the Advanced Stokes Polarimeter and to compensate for the polarization effects...
The CARMENES search for exoplanets around M dwarfs. Telluric absorption corrected high S/N optical and near-infrared template spectra of 382 M dwarf stars
Light from celestial objects interacts with the molecules of the Earth's atmosphere, resulting in the production of telluric absorption lines in ground-based...
The conceptual design of the 50-meter Atacama Large Aperture Submillimeter Telescope (AtLAST)
The (sub)millimeter sky contains a vast wealth of information that is both complementary and inaccessible to other wavelengths. Over half the light we receive...
The CoRoT ground-based asteroseismological programme
A large ground-based spectroscopic and photometric programme has accompanied the asteroseismological photometric observations of the satellite CoRoT since its...
The energy-dependent temporal variation of the ROSAT PSPC gain.
The existence of systematic spectral-fit residuals in ROSAT PSPC spectra, and their dependence on time, is by now a well established fact. This paper describes...
The ESPRESSO Redshift Drift Experiment: I. High-resolution spectra of the Lyman-α forest of QSO J052915.80-435152.0
Context. The measurement of the tiny temporal evolution in the redshift of distant objects, the redshift drift, is a powerful probe of universal expansion and...
The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper...
The European Solar Telescope (EST) is a project to design, build and operate an European Solar 4-meter class telescope to be located in the Canary Islands, with...
The First Extrasolar Planet Discovered with a New-Generation High-Throughput Doppler Instrument
We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new-generation Doppler instrument. The planet...
