Extended Data Fig. 6: Constraints on the IMBH using the acceleration measurements.
From: Fast-moving stars around an intermediate-mass black hole in ω Centauri
Taking into account the limits on the accelerations gives us additional constraints on black hole mass (a) and on-sky position (b). The contours shown correspond to the 1-, 2-, and 3-sigma levels of the distribution. This analysis using both escape velocity and acceleration measurements from the five robustly measured fast stars constrains the minimum IMBH mass stronger than escape velocity constraints alone. Both plots also show the distribution from an MCMC run including stars B and G.
