Description
We report a trimodal behaviour of the spatial distribution of ionised gas within bars in the S4G survey, in which star-forming bars are most common among late-type galaxies. We use archival GALEX far- and near-UV imaging for 772 barred galaxies and a compilation of 433 continuum-subtracted Hα images. We use both stacking techniques and visual classifications. Bars are important agents in the regulation of the star formation activity, sweeping the disk gas and triggering central starbursts.

    HARMONI at ELT: HIPOTEC electronics and control system
    HARMONI is the first light visible and near-IR integral field spectrograph for the ELT. It covers a large spectral range from 470nm to 2450nm with resolving powers from 3300 to 18000 and spatial sampling from 60 mas to 4 mas. It can operate in two Adaptive Optics modes - SCAO (including a High Contrast capability) and LTAO - or with NOAO. The

    GTCAO low-frequency tip-tilt offload to M2
    GTCAO is the instrument that implements Adaptive Optics on GTC. For atmospheric turbulence correction, GTCAO uses a deformable mirror. Unlike other AO systems, GTCAO does not include a dedicated mirror for low-frequency tip-tilt (TT) correction. In the absence of dedicated correction, the TT components of atmospheric turbulence are corrected by the
