We have derived accurate distances to Galactic globular clusters by combining data from the
Gaia Early Data Release 3 (EDR3) with distances based on Hubble Space Telescope (HST) …

We have determined masses, stellar mass functions, and structural parameters of 112 Milky
Way globular clusters by fitting a large set of N-body simulations to their velocity dispersion …

The strong equivalence principle (SEP) distinguishes general relativity (GR) from other
viable theories of gravity. The SEP demands that the internal dynamics of a self-gravitating …

Abstract We use Gaia Data Release 2 to determine the mean proper motions for 150 Milky
Way globular clusters (almost the entire known population), with a typical uncertainty of 0.05 …

General relativity and its Newtonian weak field limit are not sufficient to explain the observed
phenomenology in the Universe, from the formation of large-scale structures to the dynamics …

ABSTRACT A combination of two unsupervised machine learning algorithms, DBSCAN:
Density-Based Spatial Clustering of Applications with Noise, and GMM: Gaussian mixture …

We have used Hubble Space Telescope and ground-based photometry to determine total V-
band magnitudes and mass-to-light ratios of more than 150 Galactic globular clusters. We …

We present central velocity dispersions, masses, mass-to-light ratios (ML s), and rotation
strengths for 25 Galactic globular clusters (GCs). We derive radial velocities of 1951 stars in …

Tidal streams of disrupting dwarf galaxies orbiting around their host galaxy offer a unique
way to constrain the shape of galactic gravitational potentials. Such streams can be used as …

Context. The recent and exquisite astrometric, photometric, and radial velocity
measurements of the Gaia mission resulted in a substantial advancement of the …
