Fast-moving stars around an intermediate-mass black hole in ω Centauri
Black holes have been found over a wide range of masses, from stellar remnants with
masses of 5–150 solar masses (M☉), to those found at the centres of galaxies with M> 105 …

The parallax of ω Centauri measured from Gaia EDR3 and a direct, geometric calibration of the tip of the red giant branch and the Hubble constant
We use data from the ESA Gaia mission Early Data Release 3 (EDR3) to measure the
trigonometric parallax of ω Cen, the first high-precision parallax measurement for the most …
