Not funded by a EU programme Reference Number PID2024-155720NB-I00 Is the Job related to staff position within a Research Infrastructure? No Offer Description The candidate will make a substantial contribution to the research project "Globular cluster formation (GCform)" of Prof Mark Gieles. Globular clusters are invaluable for early Universe cosmology, galaxy formation and stellar astrophysics. Stellar-mass black holes (BHs) and intermediate-mass BHs) have been discovered in several globular clusters, and it has been suggested that globular clusters are efficient factories of dynamically assembled binary black hole (BBH) mergers observable through their gravitational wave (GW)



emission. This postdoctoral research project aims to understand star cluster formation through detailed N-body models and a comparison with observations from the Gaia space telescope. The simulations cover a range of cluster masses, densities and metallicities and will be used to achieve several science goals: (1) Understand the efficiency of the formation of binaries containing a stellar mass BH, with a particular focus on Gaia BHs in preparation of Gaia DR4. (2) Establish whether low-mass open clusters in the Milky Way contain stellar-mass black holes. (3) Benchmark the fast cluster evolution code clusterBHBdynamics (cBHBd). (4) Understand the nature of runaway massive stars * Numerical simulations, in particular N-body and stellar evolution * Simulation data analysis and code development * Critical thinking and scientific writing skills Languages ENGLISH Level Excellent Languages SPANISH
