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.

    3D scaling laws and projection effects in The300-NIKA2 Sunyaev-Zeldovich Large Program Twin Samples
    The abundance of galaxy clusters with mass and redshift is a wellknown cosmological probe. The cluster mass is a key parameter for studies that aim to constrain cosmological parameters using galaxy clusters, making it critical to understand and properly account for the errors in its estimates. Subsequently, it becomes important to correctly

    Generating galaxy clusters mass density maps from mock multiview images via deep learning
    Galaxy clusters are composed of dark matter, gas and stars. Their dark matter component, which amounts to around 80% of the total mass, cannot be directly observed but traced by the distribution of diffused gas and galaxy members. In this work, we aim to infer the cluster's projected total mass distribution from mock observational data, i.e. stars
