Description
The HST/ACS Survey of Galactic Globular Clusters includes F606W and F814W observations of 66 clusters (Sarajedini et al. 2007). We present new global mass functions (MFs) for a significant sub-sample of clusters in the survey. We also present updated core radii, tidal radii, and concentrations for many of these clusters. This new information allows us to probe correlations between the properties of the present-day stellar population, structural parameters, and the cluster's external environment.

    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
