Europium enrichment and hierarchical formation of the Galactic halo
L. Cavallo, G. Cescutti, F. Matteucci
Context. The origin of the large star-to-star variation of the [Eu/Fe] ratios observed in the extremely metal-poor (at [Fe/H]) stars of the Galactic halo is still a matter…

On the hosts of neutron star mergers in the nearby Universe
L. Cavallo, L. Greggio
Recently, the characterisation of binary systems of neutron stars has become central in various fields such as gravitational waves, gamma-ray bursts (GRBs), and the chemical evolut…

Neutron stars mergers in a stochastic chemical evolution model: impact of time delay distributions
L. Cavallo, G. Cescutti, F. Matteucci
We study the evolution of the [Eu/Fe] ratio in the Galactic halo by means of a stochastic chemical evolution model considering merging neutron stars as polluters of europium. We im…
