Since the 1970s, astronomers have struggled with the issue of how matter can be accreted
to promote black-hole growth. While low-angular-momentum stars may be devoured by a …

We analyze four epochs of Hubble Space Telescope imaging over 18 yr for the Draco dwarf
spheroidal galaxy. We measure precise proper motions for hundreds of stars and combine …

Millisecond pulsars are subject to accelerations in globular clusters (GCs) that manifest
themselves in both the first and second spin period time derivatives, and can be used to …

Globular clusters (GCs) have been proposed as promising sites for discovering intermediate-
mass black holes (IMBHs), offering the possibility to gain crucial insights into the formation …

Populations of stellar-mass black holes (BHs) in globular clusters (GCs) influence their
dynamical evolution and have important implications on one of the main formation channels …

ABSTRACT A dark star cluster (DSC) is a system in which the cluster potential is dominated
by stellar remnants, such as black holes and neutron stars having larger masses than the …

The formation and structure of the Milky Way have a fundamental role in our understanding
of the universe and its evolution, and thanks to the Gaia mission and large spectroscopic …

We present results from the search for astrometric accelerations of stars in ω Centauri using
13 yr of regularly scheduled Hubble Space Telescope WFC3/UVIS calibration observations …

We recently introduced three new parameters that describe the shape of the normalized
cumulative radial distribution (nCRD) of the innermost stars in globular clusters (GCs) and …

The Lunar Gravitational-wave Antenna (LGWA) is a proposed array of next-generation
inertial sensors to monitor the response of the Moon to gravitational waves (GWs). Given the …
