The origin of the black hole offset in M31
Pierre Boldrini
Using state-of-the-art high-resolution fully GPU N-body simulations, we demonstrate for the first time that the infall of a dark matter rich satellite naturally explains a present…
Subhalo sinking and off-center massive black holes in dwarf galaxies
Pierre Boldrini, Roya Mohayaee, Joseph Silk
Using fully GPU -body simulations, we demonstrate for the first time that subhalos sink and transfer energy via dynamical friction into the centres of dwarf galaxies. This dynam…
Embedding globular clusters in dark matter minihalos solves the cusp-core and timing problems in the Fornax dwarf galaxy
Pierre Boldrini, Roya Mohayaee, Joseph Silk
We use a fully GPU -body code to demonstrate that dark matter minihalos, as a new component of globular clusters, resolve both the timing and cusp-core problems in Fornax if the…
Cusp-to-core transition in low-mass dwarf galaxies induced by dynamical heating of cold dark matter by primordial black holes
Pierre Boldrini, Yohei Miki, Alexander Y. Wagner +3
We performed a series of high-resolution -body simulations to examine whether dark matter candidates in the form of primordial black holes (PBHs) can solve the cusp-core problem…
Fornax globular cluster distributions: implications for the cusp-core problem
P. Boldrini, R. Mohayaee, J. Silk
We re-investigate the Fornax cusp-core problem using observational results on the spatial and mass distributions of globular clusters (GCs) in order to put constraints on the dark…
Does Fornax have a cored halo? Implications for the nature of dark matter
P. Boldrini, R. Mohayaee, J. Silk
Fornax is the most massive of the Milky Way dwarf spheroidal galaxies and has five globular clusters orbiting in a dense background of dark matter. Observational analyses suggest t…
