Are ancient dwarf satellites the building blocks of the Galactic halo?
Spitoni, Emanuele; Vincenzo, F.; Matteucci, Francesca; Romano, D. (2016-05-21)According to the current cosmological cold dark matter paradigm, the Galactic halo could have been the result of the assemblage of smaller structures. Here we explore the hypothesis that the classical and ultra-faint dwarf ... -
New analytical solutions for chemical evolution models: : characterizing the population of star-forming and passive galaxies
Spitoni, Emanuele; Vincenzo, F.; Matteucci, Francesca (2017-03-01)Context. Analytical models of chemical evolution, including inflow and outflow of gas, are important tools for studying how the metal content in galaxies evolves as a function of time. Aims. We present new analytical ... -
A simple and general method for solving detailed chemical evolution with delayed production of iron and other chemical elements
Vincenzo, Fiorenzo; Matteucci, Francesca; Spitoni, Emanuele (2017-04-21)We present a theoretical method for solving the chemical evolution of galaxies by assuming an instantaneous recycling approximation for chemical elements restored by massive stars and the delay time distribution formalism ...
