Metallicity Gradients - Mass Dependency in Dwarf Elliptical Galaxies
M. Koleva, Ph. Prugniel, S. De Rijcke +2
The formation and evolution of galaxies is imprinted on their stellar population radial gradients. Two recent articles present conflicting results concerning the mass dependence of…
Formation and Evolution of Dwarf Elliptical Galaxies - II. Spatially resolved star-formation histories
Mina Koleva, Sven De Rijcke, Philippe Prugniel +2
We present optical VLT spectroscopy of 16 dwarf elliptical galaxies (or dEs) comparable in mass to NGC 205, and belonging to the Fornax cluster and to nearby groups of galaxies. Us…
A test suite for quantitative comparison of hydrodynamics codes in astrophysics
Elizabeth J. Tasker, Riccardo Brunino, Nigel L. Mitchell +5
We test four commonly used astrophysical simulation codes; Enzo, Flash, Gadget and Hydra, using a suite of numerical problems with analytic initial and final states. Situations sim…
The relation between stellar populations, structure and environment for dwarf elliptical galaxies from the MAGPOP-ITP
D. Michielsen, A. Boselli, C. J. Conselice +9
Dwarf galaxies, as the most numerous type of galaxy, offer the potential to study galaxy formation and evolution in detail in the nearby Universe. Although they seem to be simple s…
Towards a Solution for the Ca II Triplet Puzzle : Results from Dwarf Elliptical Galaxies
Dolf Michielsen, Mina Koleva, Philippe Prugniel +6
We present new estimates of ages and metallicities, based on FORS/VLT optical (4400-5500A) spectroscopy, of 16 dwarf elliptical galaxies (dE's) in the Fornax Cluster and in Souther…
The CO content of the Local Group dwarf irregular galaxies IC5152, UGCA438, and the Phoenix dwarf
Pieter Buyle, Dolf Michielsen, Sven De Rijcke +2
We present a search for CO(1->0) emission in three Local Group dwarf irregular galaxies: IC5152, the Phoenix dwarf, and UGCA438, using the ATNF Mopra radio telescope. Our scans lar…
