چکیده

A velocity dispersion has been measured for the luminous globular cluster M31 037–B327, claimed to be the most massive star cluster in the Local Group and to be a young “super star cluster” that has survived to an old age. M31 037– B327 has a mass comparable to that of M31 G1, but not significantly larger. Although near the upper end for the mass distribution of globular clusters, it is not an unprecedented extraordinary object. Subject headings: galaxies: individual (M31), galaxies: star clusters

We present the results of detailed N-body simulations regarding the interaction of four massive globular clusters in the central region of a triaxial galaxy. The systems undergo a full merging event, producing a sort of 'Super Star Cluster' (SSC) whose features are close to those of a superposition of the individual initial mergers. In contrast with other similar simulations, the resulting SSC ...

During its first cycle, the MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescope was performing an observational campaign covering a total of about 250 hours on galactic sources. Here we review the results for the very high energy (> 100 GeV) γ-ray emission from some of those sources.

Abundance ratios relative to iron for carbon, nitrogen, strontium and barium are presented for a metal-rich main sequence star ([Fe/H]=–0.74) in the globular cluster ω Centauri. This star, designated 2015448, shows depleted carbon and solar nitrogen, but more interestingly, shows an enhanced abundance ratio of strontium [Sr/Fe]≈1.6 dex, while the barium abundance ratio is [Ba/Fe]≤0.6 dex. At th...
