UGC 6728

An unassuming galaxy with an active nucleus hosting a black hole of a relatively low mass. With these observations, astronomers sought to characterize the galaxy's distance, morphology, the orbits of stars along the disk, and its globular cluster population. Each of these properties can be used together to help measure the mass of the black hole. It turns out that it is not very easy to measure such a thing, so it is best to try measuring it many different ways to see how closely they all match up.
