J/A+A/533/A36  VI photometry and velocity map of NGC 6388  (Luetzgendorf+, 2011)

Kinematic signature of an intermediate-mass black hole in the globular cluster NGC 6388. Luetzgendorf N., Kissler-Patig M., Noyola E., Jalali B., de Zeeuw P.T., Gebhardt K., Baumgardt H. <Astron. Astrophys. 533, A36 (2011)> =2011A&A...533A..36L

The aim of this work is to probe whether this massive cluster hosts an intermediate-mass black hole at its center and to compare the results with the expected value predicted by the M-σ scaling relation.
