In this seminar I will focus on how the avalanche of new data changes our views on how our Galaxy formed and evolved. Precise astrometric, spectroscopic...
The edge of the M 87 halo and the kinematics of the diffuse light in the Virgo cluster core
Aims: We study the kinematics and dynamics of the extreme outer halo of M 87, the central galaxy in the Virgo cluster, and its transition to the intracluster...
The evolution of the binary population in globular clusters: a full analytical computation
I present a simplified analytical model that simulates the evolution of the binary population in a dynamically evolving globular cluster. A number of...
The fraction of binary systems in the core of five Galactic open clusters
We used deep wide-field photometric observations to derive the fraction of binary systems in a sample of five high-latitude Galactic open clusters. By analysing...
Triaxial stellar systems following the r1/n luminosity law: an analytical mass-density expression, gravitational torques and the bulge/disc interplay
We have investigated the structural and dynamical properties of triaxial stellar systems whose surface brightness profiles follow the r1/n luminosity law -...
