Refueled and shielded - The early evolution of Tidal Dwarf Galaxies
Bernhard Baumschlager, Gerhard Hensler, Patrick Steyrleithner +1
We present, for the first time, numerical simulations of young tidal dwarf galaxies (TDGs), including a self-consistent treatment of the tidal arm in which they are embedded. There…
Globular Cluster formation in a collapsing supershell
S. Recchi, R. Wünsch, J. Palous +1
Primordial clouds are supposed to host the so-called population III stars. These stars are very massive and completely metal-free. The final stage of the life of population III sta…
Stellar hydrodynamical modeling of dwarf galaxies: simulation methodology, tests, and first results
Eduard I. Vorobyov, Simone Recchi, Gerhard Hensler
Cosmological simulations still lack numerical resolution or physical processes to simulate dwarf galaxies in sufficient details. Accurate numerical simulations of individual dwarf…
The mass-metallicity relation of tidal dwarf galaxies
S. Recchi, P. Kroupa, S. Ploeckinger
Dwarf galaxies generally follow a mass-metallicity (MZ) relation, where more massive objects retain a larger fraction of heavy elements. Young tidal dwarf galaxies (TDGs), born in…
The IGIMF and other IMFs in dSphs: the case of Sagittarius
Fiorenzo Vincenzo, Francesca Matteucci, Simone Recchi +3
We have studied the effects of various initial mass functions (IMFs) on the chemical evolution of the Sagittarius dwarf galaxy (Sgr). In particular, we tested the effects of the in…
Photoionization analysis of chemo-dynamical dwarf galaxies simulations
B. Melekh, S. Recchi, G. Hensler +1
Photoionization modelling allows to follow the transport, the emergence, and the absorption of photons taking into account all important processes in nebular plasmas. Such modellin…
