The influence radius of the supermassive black hole at the Galactic Center is about 2–3 parsecs (pc), and a Bahcall–Wolf cusp if present would extend outward to a distance of about 0.5 pc from the supermassive black hole. A region of this size is easily resolved from Earth. However, no cusp is observed; instead, the density of the oldest stars is flat or even declining toward the Galactic Center. This observation does not necessarily rule out the existence of a Bahcall–Wolf cusp in some still unobserved component. However, current observations imply a relaxation time at the Galactic Center of roughly 10 billion years, comparable with the age of the Milky Way. While it had been considered that it could be that not enough time had elapsed for a Bahcall–Wolf cusp to form, we have nowadays observational evidence that there is an old, segregated cusp at the Galactic Centre. These observations coincide with the predictions of dedicated models.
