Numerical Simulations of the Metallicity Distribution in Dwarf Spheroidal Galaxies
Recent observations show that the number of stars with very low metallicities in the dwarf spheroidal satellites of the Milky Way is low, despite the low...
Numerical test of a new v-profile inversion technique
The diagnostic method proposed by Landi Degl'Innocenti and Landolfi (1982), based on the observation of circular polarization, has been generalized to derive...
OASIS high-resolution integral field spectroscopy of the SAURON ellipticals and lenticulars
We present a summary of high-spatial resolution follow-up observations of the elliptical (E) and lenticular (S0) galaxies in the SAURON survey using the OASIS...
Stellar rotation, parameterized by a star's projected rotational velocity v sin i, is a fundamental parameter linked to star formation, evolution, and dynamical...
From observations taken with the Wide Field Camera (WFC) at the Isaac Newton Telescope (INT), we have built an astrometric and photometric catalogue of stars in...
