GalCEM. I. An Open-source Detailed Isotopic Chemical Evolution Code

Autor: Eda Gjergo, Aleksei G. Sorokin, Anthony Ruth, Emanuele Spitoni, Francesca Matteucci, Xilong Fan, Jinning Liang, Marco Limongi, Yuta Yamazaki, Motohiko Kusakabe, Toshitaka Kajino

Publikováno v: The Astrophysical Journal Supplement Series, Vol 264, Iss 2, p 44 (2023)

This is the first of a series of papers that will introduce a user-friendly, detailed, and modular Galactic Chemical Evolution Model , GalCEM , that tracks isotope masses as a function of time in a given galaxy. The list of tracked isotopes automatic

A Bayesian chemical evolution model of the DustPedia Galaxy M74

Autor: Francesco Calura, Marco Palla, Laura Morselli, Emanuele Spitoni, Viviana Casasola, Kuldeep Verma, Andrea Enia, Massimo Meneghetti, Simone Bianchi, Francesca Pozzi, Carlotta Gruppioni

Publikováno v: Monthly Notices of the Royal Astronomical Society.

We introduce a new, multi-zone chemical evolution model of the DustPedia galaxy M74, calibrated by means of MCMC methods. We take into account the observed stellar and gas density profiles and use Bayesian analysis to constrain two fundamental parame

Origin of neutron capture elements with the Gaia-ESO survey: the evolution of s- and r-process elements across the Milky Way

Autor: Marta Molero, Laura Magrini, Francesca Matteucci, Donatella Romano, Marco Palla, Gabriele Cescutti, Carlos Viscasillas Vázquez, Emanuele Spitoni

We study the abundance patterns and the radial gradients of s-process elements (Y, Zr, Ba, La and Ce), r-process elements (Eu) and mixed-process elements (Mo, Nd and Pr) in the Galactic thin disc by means of a detailed two-infall chemical evolution m

Electron distribution in the Galactic disc: results from a non-equilibrium ionization model of the interstellar medium

Autor: Dieter Breitschwerdt, Miguel A. de Avillez, Ashish Asgekar, Emanuele Spitoni

Publikováno v: Monthly Notices of the Royal Astronomical Society: Letters. 423:L107-L111

Using 3D non-equilibrium ionization hydrodynamical simulation of the interstellar medium, we study the electron density, ne, in the Galactic disc and compare it with the values derived from dispersion measures (DMs) towards pulsars with known distanc

The effect of radial gas flows on the chemical evolution of the Milky Way and M31

Autor: Emanuele Spitoni, Matteucci, F.

Publikováno v: Scopus-Elsevier

We present detailed chemical evolution models for the Milky Way and M31 in presence of radial gas flows. These models follow in detail the evolution of several chemical elements (H, He, CNO, $\alpha$ elements, Fe-peak elements) in space and time. The

Galassia che vai, abitabilità che trovi

Autor: Emanuele Spitoni

Essere terrestri nella Via Lattea o alieni in Andromeda non è la stessa cosa. Nella nostra galassia le zone abitabili sono più centrali, nella galassia Andromeda è necessario adattarsi alla 'periferia' a causa degli effetti delle supernovae, molto

Until recently the dynamical evolution of the interstellar medium (ISM) was simulated using collisional ionization equilibrium (CIE) conditions. However, the ISM is a dynamical system, in which the plasma is naturally driven out of equilibrium due to
