According to Baade (1944) the stellar population in the central bulge of M31 resolves at the same magnitude level as do the globular clusters associated with that galaxy. This observation led Baade to conclude that the nuclear bulge of the Andromeda Nebula consists of globular cluster-like stars...
Comparing the gravitational acceleration induced on the Local Group of galaxies by different tracers of the underline density field we estimate, within the linear gravitational instability theory and the linear biasing ansatz, their relative bias factors. Using optical SSRS2 galaxies, IRAS (PSCz) galax...
Their number distribution is fitted very well by a power law with index alpha similar to 1.5 +/- 0.7, which is consistent with the cluster mass functions of other Local Group galaxies and the cluster initial mass function. In addition to the detected star clusters of the galaxy, the ...
This finding confirms an effect previously noted in the Virgo Cluster and the Hydra Cluster. Moreover, the NGC 1399 globular cluster system structurally resembles that in M87, the dominant central giant elliptical galaxy in the Virgo Cluster. Such galaxies seem to be preferred locations for the ...

Virgo Galactic ClusterObservations of the Local Supercluster are examined for evidence of processes of galaxy formation and compared with theories for closed and open universes. Redshift measurements of the Galaxy have revealed that the Local Supercluster contains 60% of its galaxies in a thin disk,...
NGC 3109 (bottom right) is another dwarf irregular galaxy of several hundred million stars and it is also the largest member of a small sub-group of galaxies within the Local Group.
