Dynamics of supernova remnants in the Galactic Centre
Elisa Bortolas, Michela Mapelli, Mario Spera
The Galactic centre (GC) is a unique place to study the extreme dynamical processes occurring near a super-massive black hole (SMBH). Here we simulate a large set of binaries orbit…
Brownian motion of massive black hole binaries and the final parsec problem
E. Bortolas, A. Gualandris, M. Dotti +2
Massive black hole binaries (BHBs) are expected to be one of the most powerful sources of gravitational waves (GWs) in the frequency range of the pulsar timing array and of forthco…
Shedding light on the black hole mass spectrum
Mario Spera, Nicola Giacobbo, Michela Mapelli
The mass spectrum of stellar black holes (BHs) is highly uncertain. Theoretical models of BH formation strongly depend on the efficiency of stellar winds of the progenitor star and…
Do open star clusters evolve toward energy equipartition?
Mario Spera, Michela Mapelli, Robin D. Jeffries
We investigate whether open clusters (OCs) tend to energy equipartition, by means of direct N-body simulations with a broken power-law mass function. We find that the simulated OCs…
