Description
Preliminary results on new CCD photometry inV andB bands of approximately 5000 stars in four overlapping fields in the globular cluster M3 are presented. The colour-magnitude diagram shows a very well-defined sequence with a small scatter, going fainter than previously published work on this cluster. The turn-off point found atV=19.1±0.2 mag and (B-V)=0.445±0.01, is slightly redder than those obtained in previous studies.

    Estimation of the hydrostatic-to-lensing mass bias from resolved cluster masses
    We present a study on the bias of hydrostatic masses with respect to lensing mass estimates for a sample of 53 clusters in a redshift range between z = 0.05 and 1.07. The M 500 mass for each cluster was inferred from X-ray and lensing data, without using a priori observable-mass scaling relations. Cluster masses of our reference analysis were

    IRAM 30-meter millimeter follow-up of deep OSIRIS-GTC optical surveys
    It is broadly accepted that CO is a reliable tracer of H2 in massive IR (L IR ≳ 10 9 L ⊙) galaxies, and that there are clear correlations between L IR and L' CO that are qualitatively independent of environment and even redshift. We present two tales on the search for 12CO emission from dusty star-forming galaxies in both field (Lockman Hole, z < 0

    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
