Descripción
ESPRESSO is a fiber feed ultrastable High Resolution Spectrograph designed to work in the Combined-Coudé focus of Very Large Telescopes (VLT). A high resolution (R 100000) and an ultra-high resolution (R 220000) mode will be available to collect the light coming of one VLT telescope. In addition, ESPRESSO has an observing mode which allows to collect light of 2, 3 or 4 VLT units. This mode can feed simultaneously the spectrograph using a 4x1 fiber combiner. In the combiner, the light from 4 octagonal fibers will be mixed when projected onto a square fiber, as a double scrambler device. Here it is presented the design, manufacture, integration and tests for the 4x1 combiner of the ESPRESSO Fiber Link.

    A new era in galaxy edge characterisation with ultra-deep imaging
    For the first time, the LIGHTS survey is routinely imaging galaxies at a depth and spatial resolution comparable to what LSST will produce in 10 years (i.e. ~31 mag/arcsec^2). This opens up the possibility of probing the edge of galaxies with a precision that we have not been able to achieve in the past. While we have been limited to one

    Exploring the role of galaxy interactions in fuelling active galactic nuclei: mergers, star formation, and supermassive black hole accretion
    Supermassive black holes require a reservoir of cold gas at the centre of their host galaxy in order to accrete and shine as active galactic nuclei (AGN). Major mergers have the ability to drive gas inwards through the strong tidal torques involved, but observations trying to link mergers with AGN have found mixed results due to the difficulty of

    Star formation at the edge of galaxies
    At the edge of galaxies, in the lowest surface brightness regimes, lies the boundary where gas can collapse to form new stars. These regions remain largely unexplored due to the lack of very deep images that allow us to characterize the star-forming clumps at the edge of the discs. In this sense, we do not know whether stellar activity in these
