New Signatures of the Milky Way Formation in the Local Halo and Inner Halo Streamers in the Era of Gaia
Paola Re Fiorentin, Mario G. Lattanzi, Alessandro Spagna +1
We explore the vicinity of the Milky Way through the use of spectro-photometric data from the Sloan Digital Sky Survey and high-quality proper motions derived from multi-epoch posi…
Properties of barred spiral disks in hydrodynamical cosmological simulations
David Goz, Pierluigi Monaco, Giuseppe Murante +1
We present a quantification of the properties of bars in two N-body+SPH cosmological simulations of spiral galaxies, named GA and AqC. The initial conditions were obtained using th…
The radial metallicity gradients in the Milky Way thick disk as fossil signatures of a primordial chemical distribution
A. Curir, A. L. Serra, A. Spagna +3
In this letter we examine the evolution of the radial metallicity gradient induced by secular processes, in the disk of an -body Milky Way-like galaxy. We assign a [Fe/H] value…
The thick disk rotation-metallicity correlation as a fossil of an "inverse chemical gradient" in the early Galaxy
Anna Curir, Mario G. Lattanzi, Alessandro Spagna +4
The thick disk rotation--metallicity correlation, \partial V_ϕ/\partial[Fe/H] =40÷50 km s^{-1}dex^{-1} represents an important signature of the formation processes of the galactic…
Assembly of the outer Galactic stellar halo in the hierarchical model
Giuseppe Murante, Eva Poglio, Anna Curir +1
We provide a set of numerical N-body simulations for studying the formation of the outer Milky Ways's stellar halo through accretion events. After simulating minor mergers of progr…
Evolution and instabilities of disks harboring super massive black holes
Anna Curir, Valentina de Romeri, Giuseppe Murante
The bar formation is still an open problem in modern astrophysics. In this paper we present numerical simulation performed with the aim of analyzing the growth of the bar instabili…
