Galaxy Pairs in the Local Group
Azadeh Fattahi, Julio F. Navarro, Else Starkenburg +2
Current models of galaxy formation predict that galaxy pairs of comparable magnitudes should become increasingly rare with decreasing luminosity. This seems at odds with the relati…
Dark satellites and the morphology of dwarf galaxies
Amina Helmi, L. V. Sales, E. Starkenburg +4
One of the strongest predictions of the LambdaCDM cosmological model is the presence of dark satellites orbiting all types of galaxies. We focus here on the dynamical effects of su…
Not too big, not too small: the dark halos of the dwarf spheroidals in the Milky Way
Carlos A. Vera-Ciro, Amina Helmi, Else Starkenburg +1
We present a new analysis of the Aquarius simulations done in combination with a semi-analytic galaxy formation model. Our goal is to establish whether the subhalos present in LCDM…
Cleaning spectroscopic samples of stars in nearby dwarf galaxies: The use of the nIR MgI line to weed out Milky Way contaminants
Giuseppina Battaglia, Else Starkenburg
Dwarf galaxies provide insights on the processes of star formation and chemical enrichment at the low end of the galaxy mass function, as well as on the clustering of dark matter o…
The Star Formation & Chemical Evolution History of the Sculptor Dwarf Spheroidal Galaxy
T. J. L. de Boer, E. Tolstoy, V. Hill +6
We have combined deep photometry in the B,V and I bands from CTIO/MOSAIC of the Sculptor dwarf spheroidal galaxy, going down to the oldest Main Sequence Turn-Offs, with spectroscop…
