Probing the formation history of the nuclear star cluster at the Galactic Centre with millisecond pulsars

Understand

The origin of the Nuclear Star Cluster in the centre of our Galaxy is still unknown.

• One possibility is that it formed after the disruption of stellar clusters that spiralled into the Galactic Centre due to dynamical friction.
• We trace the formation of the Nuclear Star Cluster around the central black hole, using state-of-the-art N-body simulations, and follow the dynamics of the neutron stars born in the clusters.
• We then estimate the number of Millisecond Pulsars (MSPs) that are released in the Nuclear Star Cluster, during its formation.
