Description
Synthetic horizontal branch (HB) stars in globular clusters, when computed on the basis of HB evolutionary tracks and pulsation theory constraints, furnish the best theoretical scenarios for exploration of the age-metallicity relation in globular clusters. Preliminary results are presented from recently computed synthetic models of the horizontal branch. The primary properties predicted for HB stars and RR Lyrae variables are presented and compared with selected observations of variables in the field and in globular clusters.

    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

    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

    Gas Flows in the Central Region of NGC 4593 with Muse
    Understanding how gas flows into galactic centers, fuels the AGN and in turn is expelled back through feedback processes is of great importance to appreciate the role AGN play in the growth and evolution of galaxies. We use MUSE-AO optical spectra of the inner 7''. 5 × 7''. 5 of the nearby Seyfert 1 galaxy NGC 4593 to understand how gas flows in
