Descripción
The interstellar medium of early type galaxies has attracted a great deal of interest ever since Faber & Gallagher (1976) showed that a considerable amount of mass ejected by evolved stars could pile up over the lifetime of the galaxy (10^8 - 10^9 M[ scriptstyle sun ]). Surprisingly though, high resolution and sensitive HI observations demonstrated that in general much less gas is detected and that most of it seems to have been accreted (van Gorkom et al 1986; Wiklind & Henkel 1990). We have started a project, mapping a few early-type galaxies in detail, in order to shed light on the origin of the ISM in these objects.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    The Multi Frequency Instrument 2 (MFI2): mechanical design, manufacture, integration, and commissioning of the MFI2 for the QUIJOTE facility in Tenerife (Canary Islands)
    The QUIJOTE (Q-U-I JOint TEnerife) experiment combines the operation of two radio-telescopes and three instruments working in the microwave bands from 10 to 47 GHz at the Teide Observatory, Tenerife, which has already been presented in previous SPIE meetings. The new Multi Frequency Instrument (MFI2) led by the Instituto de Astrofísica de Canarias

    ANDES, the high-resolution spectrograph for the ELT: RIZ & UBV spectrographs' preliminary design, analysis, and integration of the vacuum vessel and thermal enclosure
    The RIZ & UBV visible spectrographs of the ANDES instrument, which are foreseen to be installed at the Extremely Large Telescope, require to be under a very stable high vacuum and at an extremely stable temperature of 1mK to reach the radial velocity goal of 10cm/s RMS over a 10-year period. The baseline design, integration and first analyses of
