Description
We present evidences of extended line-emission in the quadruple system Q2237+0305. Using 2D spectroscopy obtained with the fiber based system INTEGRAL in subarcsecond seeing conditions, we have derived intensity maps for the continuum and the emission in the CIII]lambda1909 line. The continuum maps show four distinct compact sources which agree in location with the point like sources found in the HST images. In addition to these four compact sources, the CIII]lambda1909 map also shows an arc of extended emission. The morphology of the arc is qualitatively consistent with models accounting for the compact sources. The observed arc can be interpreted as a gravitational lens image of an extended star forming region in the QSO host.

    ANDES, the high-resolution spectrograph for the ELT: design of the adaptive optics system
    ANDES,the high resolution spectrograph for the ELT, will work both in seeing limited mode and with Adaptive Optics (AO) correction. ANDES-SCAO is a single conjugated AO system working with natural guide stars, feeding the IFU coupled to the YJH spectrograph. The main science goal of the ANDES AO mode is the characterization of the exo-planet
