ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments
A. Marconi, M. Abreu, V. Adibekyan +286
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
ANDES, the high-resolution spectrograph for the ELT: RIZ Spectrograph preliminary design
Bruno Chazelas, Yevgeniy Ivanisenko, Audrey Lanotte +44
We present here the preliminary design of the RIZ module, one of the visible spectrographs of the ANDES instrument 1. It is a fiber-fed high-resolution, high-stability spectrograph…
HIRES, the high-resolution spectrograph for the ELT
Alessandro Marconi, Manuel Abreu, Vardan Adibekyan +99
HIRES will be the high-resolution spectrograph of the European Extremely Large Telescope at optical and near-infrared wavelengths. It consists of three fibre-fed spectrographs prov…
ESPRESSO@VLT -- On-sky performance and first results
F. Pepe, S. Cristiani, R. Rebolo +97
ESPRESSO is the new high-resolution spectrograph of ESO's Very-Large Telescope (VLT). It was designed for ultra-high radial-velocity precision and extreme spectral fidelity with th…
Rotational and rotational-vibrational Raman spectroscopy of air to characterize astronomical spectrographs
F. P. A. Vogt, F. Kerber, A. Mehner +14
Raman scattering enables unforeseen uses for the laser guide-star system of the Very Large Telescope. Here, we present the observation of one up-link sodium laser beam acquired wit…
ESPRESSO: The next European exoplanet hunter
F. Pepe, P. Molaro, S. Cristiani +55
The acronym ESPRESSO stems for Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations; this instrument will be the next VLT high resolution spectrograph. T…
