Science potential for stellar-mass black holes as neighbors of Sgr A*
ORAL
Abstract
There is a possibility that stellar-mass black holes inhabit near the massive black hole Sgr A* that is located at the center of our galaxy. Such scenarios are motivated by the mass segregation of stellar-mass black holes on the massive end and disk migration if there were an active accretion flow near Sgr A*. In this talk, I will focus on applications of such objects as sources of space-borne gravitational wave detector LISA. In particular, I will discuss the prospect of measuring the spin of Sgr A* with gravitational waves observations with LISA. I will further discuss the possibility of detecting the signature of dark matter clouds around Sgr A* as well as multi-body gravitational interactions.
