Descripción
This paper presents examples of star-forming phenomena in the discs of spirals which show symptoms of phase-coherence over kpc scales. Cases are found where, along an arm, the youngest blue stars are coherently displaced from a recent but older generation of redder evolved supergiants; in other cases, the star formation efficiency in arms appears to be responding to a density wave resonance pattern. Cases were also found with axisymmetric outflow in the disc components of circumnuclear starburst zones, which could account for an evolutionary starburst-LINER sequence.

    New Robotic Telescope system progress towards critical design review
    The 4m class New Robotic Telescope (NRT) is an optical facility designed to revolutionize the rapid follow-up and classification of variable and transient objects. The project is at the stage where key systems are progressing through their detailed design phases, which presents a major engineering challenge for all project partners to manage design

    Phase diversity application on the EST MCAO testbench
    Phase Diversity (PD) is a technique widely used to measure and compensate for Non-Common Path Aberrations (NCPA) in optical systems. Beyond its traditional applications, PD has found further uses in solar astrophysics, where it enhances image quality by processing multiple images to correct residual aberrations. In this work, we introduce a

    First light of the upgraded Gregor Infrared Spectrograph
    For more than ten years, the Gregor Infrared Spectrograph (GRIS) has been the infrared spectropolarimeter on the Gregor telescope since its inauguration in 2012. The instrument mainly performs polarimetric observations of the wavelength regions at 1083 and 1565nm, which have high scientific potential. There, observers can find spectral lines that
