1) Polarized Line Formation theories: the relevance of partial non-coherence in light scattering. Dr. Sampoorna Malali The basic theoretical tool for diagnosing...
I will present an evolutionary model for the origin of Andromeda II, a dSph satellite of M31, involving a merger between two disky dwarf galaxies than explains...
A cyclical approximation of the evolutionary synthesis of stellar populations has been developed into a general solution for the mass and time-dependence of the...
Dark matter makes up most of the mass of the Universe but remains mysterious. I discuss recent progress in constraining its properties by measuring its...
About 500 asymptotic giant branch (AGB) stars have been resolved and photometrically measured in the Local Group (LG) dwarf irregular galaxy NGC 6822. They draw...
We present accurate B, V, R photometry of the Sculptor dwarf spheroidal galaxy. The data have been collected with the Wide Field Imager available at 2.2 m ESO...
According to the current concordance cosmological model, dark matter (DM) particles are collisionless and produce self-gravitating structures with a central...
CCD UBV photometry of 2279 stars in Sextans A is presented. Differences with the photometric scales of Sandage and Carlson (1985) and Hoessel et al. (1983) are...
CCD photometry of resolved dwarf irregular galaxies was obtained with the 4-m Cerro Tololo Interamerican Observatory telescope in February 1985. BV data from 77...
