Faint objects in motion: the new frontier of high precision astrometry
Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Internal rotation of Milky Way dwarf spheroidal satellites with Early Data Release 3
Alberto Manuel Martínez-García, Andrés del Pino, Antonio Aparicio +2
We present an analysis of the kinematics of 14 satellites of the Milky Way (MW). We use proper motions (PMs) from the Early Data Release 3 (EDR3) and line-of-sight velocitie…
Hunting for intermediate-mass black holes in globular clusters: an astrometric study of NGC 6441
Maximilian Häberle, Mattia Libralato, Andrea Bellini +6
We present an astrometric study of the proper motions (PMs) in the core of the globular cluster NGC 6441. The core of this cluster has a high density and observations with current…
