Numerical simulations of dwarf galaxy merger trees
Annelies Cloet-Osselaer, Sven De Rijcke, Bert Vandenbroucke +3
We investigate the evolution of dwarf galaxies using N -body/SPH simulations that incorporate their formation histories through merger trees constructed using the ex- tended Press-…
Gaseous infall triggering starbursts in simulated dwarf galaxies
Robbert Verbeke, Sven De Rijcke, Mina Koleva +3
Using computer simulations, we explored gaseous infall as a possible explanation for the starburst phase in Blue Compact Dwarf galaxies. We simulate a cloud impact by merging a sph…
On the origin of bursts in blue compact dwarf galaxies: clues from kinematics and stellar populations
M. Koleva, S. De Rijcke, W. W. Zeilinger +3
Blue compact dwarf galaxies (BCDs) form stars at, for their sizes, extraordinarily high rates. In this paper, we study what triggers this starburst and what is the fate of the gala…
Stellar orbits and the survival of metallicity gradients in simulated dwarf galaxies
Joeri Schroyen, Sven De Rijcke, Mina Koleva +2
We present a detailed analysis of the formation, evolution, and possible longevity of metallicity gradients in simulated dwarf galaxies. Specifically, we investigate the role of po…
New composition dependent cooling and heating curves for galaxy evolution simulations
Sven De Rijcke, Joeri Schroyen, Bert Vandenbroucke +4
In this paper, we present a new calculation of composition-dependent radiative cooling and heating curves of low-density gas, intended primarily for use in numerical simulations of…
Physics of a partially ionized gas relevant to galaxy formation simulations -- the ionization potential energy reservoir
Bert Vandenbroucke, Sven De Rijcke, Joeri Schroyen +1
Simulation codes for galaxy formation and evolution take on board as many physical processes as possible beyond the standard gravitational and hydrodynamical physics. Most of this…
The degeneracy between star-formation parameters in dwarf galaxy simulations and the Mstar-Mhalo relation
Annelies Cloet-Osselaer, Sven De Rijcke, Joeri Schroyen +1
We present results based on a set of N-Body/SPH simulations of isolated dwarf galaxies. The simulations take into account star formation, stellar feedback, radiative cooling and me…
Simulations of the formation and evolution of isolated dwarf galaxies - II. Angular momentum as a second parameter
Joeri Schroyen, Sven De Rijcke, Sander Valcke +2
We show results based on a large suite of N-Body/SPH simulations of isolated, flat dwarf galaxies, both rotating and non-rotating. The main goal is to investigate possible mechanis…
Simulations of the formation and evolution of isolated dwarf galaxies
Sander Valcke, S. De Rijcke, H. Dejonghe
We present new fully self-consistent models of the formation and evolution of isolated dwarf galaxies. We have used the publicly available N-body/SPH code HYDRA, to which we have a…
