Equinox, what a controversial concept! Since the dawn of archaeoastronomy this has arguably been the most problematic concept—perhaps together with the lunar...
Doing research is fighting, what any other thing the human being could do? Fight against powers or to get powers, that depends on us. Science can be a...
What is the Upper Limit on the Lightest Supersymmetric Higgs Mass?
In this talk the question of what is the upper bound on the lightest supersymmetric Higgs mass, m_h is addressed. This question is relevant since experimental...
What stars can tell us about galaxies: star formation histories in the Local Group
The formation and evolution of Local Group galaxies can be studied in the greatest possible detail thanks to the possibility of obtaining photometry and...
When binaries keep track of recent nucleosynthesis
We determine Zr and Nb elemental abundances in barium stars to probe the operation temperature of the s-process that occurred in the companion asymptotic giant...
When disks collide: major and minor mergers in disk galaxies
We present the surface brightness profile fitting of a sample of double nucleus disk galaxies, minor merger candidates. We have decomposed these systems into...
Several recent studies indicate that bulges are more complex than merely structureless relaxed stellar systems. We study the HST images of a sample of 130...
