Description
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.

    Massive characterisation of subgiants and red giants with TESS (Kepler and Gaia)
    TESS serves as a formidable tool for investigating stellar variability. Nonetheless, the adaptation of methodologies employed in other space missions, such as Kepler, to deduce long stellar rotation periods or solar-like stellar pulsations has been a challenge. The advent of multiple sectors of data for most stars every two years with the extended

    We present a 0.35-2.4 µm stellar spectral library composed by 31 stars observed with the Gemini Near-IR Spectrograph (GNIRS) on the 8.1 m Gemini North telescope in Mauna Kea, Hawaii. These stars are present in the MILES library, and thus various parameters derived from the optical are available. Furthermore, out of those, 26 are presented for the

    Calibrating the color-redshift relation for an optimum exploitation of Euclid data
    Euclid's three dimensional reconstruction of the matter distribution in the Universe heavily relies on a proper calibration of the color-redshift relation. Getting such calibration was the motivation of the project Complete Calibration of the Color-Redshift Relation (C3R2) survey (Masters et al. 2017), with the goal of mapping the empirical
