Does the Sagittarius Stream constrain the Milky Way halo to be triaxial?

Rodrigo Ibata, Geraint F. Lewis, Nicolas F. Martin +2

Recent analyses of the stellar stream of the Sagittarius dwarf galaxy have claimed that the kinematics and three-dimensional location of the M-giant stars in this structure constra…

Dwarf Galaxies and Globular Clusters

Michele Bellazzini

I briefly explore some relevant connections and differences between the evolutionary paths of dwarf galaxies and globular clusters.

The horizontal branch morphology of M31 globular clusters. Extreme second parameter effect in outer halo clusters

S. Perina, M. Bellazzini, A. Buzzoni +4

We use deep, high quality colour magnitude diagrams obtained with the Hubble Space Telescope to compute a simplified version of the Mironov index [SMI; B/(B+R)] to parametrize the…

The horizontal branch luminosity vs metallicity in M31 globular clusters

Luciana Federici, Carla Cacciari, Michele Bellazzini +3

Thanks to the outstanding capabilites of the HST, our current knowledge about the M31 globular clusters (GCs) is similar to our knowledge of the Milky Way GCs in the 1960s-1970s, w…

News from the Galactic suburbia: the chemical composition of the remote globular cluster NGC 2419

A. Mucciarelli, M. Bellazzini, R. Ibata +4

We present the chemical analysis of 49 giant stars of the globular cluster NGC 2419, using medium resolution spectra collected with the multi-object spectrograph DEIMOS@Keck. Previ…

A comparison between the stellar and dynamical masses of six globular clusters

A. Sollima, M. Bellazzini, J. -W. Lee

We present the results of a comprehensive analysis of the structure and kinematics of six Galactic globular clusters. By comparing the results of the most extensive photometric and…
