The Origin of the Mass-Radius Relation of Early-Type Galaxies
Cesare Chiosi, Emiliano Merlin, Lorenzo Piovan
Early-type galaxies obey a narrow relation traced by their stellar content between the mass and size (Mass- Radius relation). The wealth of recently acquired observational data ess…
Formation and Evolution of Early-Type Galaxies. III Star formation history as a function of mass and over-density
Emiliano Merlin, Cesare Chiosi, Lorenzo Piovan +3
We investigate the influence of the initial proto-galaxies over-densities and masses on their evolution, to understand whether the internal properties of the proto-galactic haloes…
Orbital evolution of the Carina dwarf galaxy and self-consistent star formation history determination
S. Pasetto, E. K. Grebel, P. Berczik +2
We present a new study of the evolution of the Carina dwarf galaxy that includes a simultaneous derivation of its orbit and star formation history. The structure of the galaxy is c…
Formation and Evolution of Early-Type Galaxies: Spectro-Photometry from Cosmo-Chemo-Dynamical Simulations
Rosaria Tantalo, Simonetta Chinellato, Emiliano Merlin +2
One of the major challenges in modern astrophysics is to understand the origin and the evolution of galaxies, the bright, massive early type galaxies (ETGs) in particular. Therefor…
EvoL: The new Padova T-SPH parallel code for cosmological simulations - I. Basic code: gravity and hydrodynamics
Emiliano Merlin, Umberto Buonomo, Tommaso Grassi +2
We present EvoL, the new release of the Padova N-body code for cosmological simulations of galaxy formation and evolution. In this paper, the basic Tree + SPH code is presented and…
GALEX UV properties of the polar ring galaxy MCG-05-07-001 and the shell galaxies NGC 1210 and NGC 5329
A. Marino, E. Iodice, R. Tantalo +7
Systems of shells and polar rings in early-type galaxies are considered "bona fide" tracers of mass accretion and/or mergers. Their high frequency in low density environments sugge…
