TL;DR: In this article, an analysis of ages, metallicities, and [α/Fe] ratios of globular cluster systems in early-type galaxies is presented, based on Lick index measurements summarized in Puzia et al.

TL;DR: The 4MOST project as mentioned in this paper proposes a wide-field (3 square degree, goal >5 square degree), high-multiplex (1500 fibres, goal 3000 fibres) spectroscopic survey facility for an ESO 4m-class telescope.

TL;DR: In this article, a correlation between the mass of a galaxy's central black hole and the luminosity-weighted line-of-sight velocity dispersion sigma_e within the half-light radius is described.

TL;DR: In this article, high-dynamic-range surface photometry was used to measure the stellar light deficits L def and mass deficits M def associated with the cores of elliptical galaxies and showed that L def correlates with velocity dispersions σ of the host galaxy bulge averaged outside the central region that may be affected by a supermassive black hole.

TL;DR: In this paper, the authors present validated Euclid cosmological forecasts for galaxy clustering, weak lensing, and the combination thereof, which combine both theoretical and observational ingredients for different Cosmological probes.
