Description
High resolution bidimensional optical spectroscopy in H-alpha line, N II forbidden line at 6548 and 6583 A, and S II forbidden line at 6717 and 6713 A, of the bipolar nebula S 106 are reported. The resulting H-alpha velocity maps show strong variations in the emission line profiles along the nebula, a situation which is duplicated in other lines, and suggest a subarcsec scale structure for some zones. The clumpiness of the nebula is furthermore evidence by the presence of line splitting with typical relative velocities of about 90 km/s. A possible model for this nebula is discussed, taking into account its morphological, physical and kinematic characteristics.

    ANDES, the high resolution spectrograph for the ELT: science goals, project overview, and future developments
    The first generation of ELT instruments includes an optical-infrared high resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion Echelle Spectrograph). ANDES consists of three fibre-fed spectrographs ([U]BV, RIZ, YJH) providing a spectral resolution of ∼100,000 with a minimum simultaneous wavelength

    ANDES, the high-resolution spectrograph for the ELT: UBV spectrograph preliminary design
    We present the design of the ANDES UBV module, the bluest spectrograph of the ANDES instrument. It is a fiber-fed high resolution, high stability spectrograph, which will be installed on the ELT-Nasmyth platform to minimize blue fibre losses from the focal plane to the spectrograph. In this paper we present the status of development of the
