Calibrating spectral siren cosmology with synthetic catalogs of binary black hole mergers
Arianna Scarpa, Simone Mastrogiovanni, Filippo Santoliquido +2
Binary black hole (BBH) mergers detected through Gravitational Waves (GWs) are a promising probe for the cosmic expansion. These sources are standard sirens for which we can direct…
Can dark energy explain the observed outflow in galaxy clusters?
M. Donnari, M. Arca-Sedda, M. Merafina
Recent observations of the Virgo cluster and the Local Group suggested that some galaxies are flowing out from their parent cluster. This may be the signature that dark energy (DE)…
Dynamical friction in cuspy galaxies
Manuel Arca-Sedda, Roberto Capuzzo-Dolcetta
In this paper we treat the problem of the dynamical friction decay of a massive object moving in an elliptical galaxy with a cuspidal inner distribution of the mass density. We pre…
Dynamical Friction in Cuspidal Galaxies
M. Arca-Sedda, R. Capuzzo-Dolcetta
Dynamical friction is the process responsible for matter transport toward the inner regions of galaxies in form of massive objects, like intermediate mass black holes, globular clu…
The Dense Stellar Systems Around Galactic Massive Black Holes
R. Capuzzo-Dolcetta, M. Arca-Sedda, M. Spera
The central regions of galaxies show the presence of massive black holes and/or dense stellar systems. The question about their modes of formation is still under debate. A likely e…
