Observational signatures of the black hole Mass Distribution in the Galactic Center

Understand

We simulate the star cluster, made of stars in the main sequence and different black hole (BH) remnants, around SgrA* at the center of the Milky Way galaxy.

• Tracking stellar evolution, we find the BH remnant masses and construct the BH mass function.
• We sample 4 BH species and consider the impact of the mass-function in the dynamical evolution of system.
• Starting from an initial 6 dimensional family of parameters and using an MCMC approach, we find the best fits to various parameters of model by directly comparing the results of the simulations after $t = 10.5$ Gyrs with current observations of the stellar surface density, stellar mass profile and the mass of SgrA*.
