... We present V and I photometry for a sample of globular cluster candidates in the Virgo galaxy M87. ... A comparison with the color distribution of globular clusters in the Milky Way shows that M87 contains a large population of red clusters that is virtually absent in our Galaxy. ... Increasingly accurate measurements of the colors and metallicities of globular clusters in distant galaxies are beginning to shed new light on, and provoke new questions about, the origin of globular cluster systems. ...

... The Thickness of Stellar Disks in Early-type Galaxies E. M. Chudakova* and O. K. Sil'chenko ** Sternberg Astronomical Institute, Lomonosov Moscow State University, Moscow, Russia Received August 19, 2013; in final form, October 30, 2013 Abstract--We suggest and justify a new photometric method enabling the derivation of the relative thickness of a galactic disk from the two-dimensional surface-brightness distribution of the galaxy in the plane of the sky. ...

Rep ort by the ESA-ESO Working Group on Galactic p opulations, chemistry and dynamics Abstract Between the early 40s, when Baade showed the first evidence for the existence of two distinct stellar populations, and today, with our Galaxy surprising us with new substructures discovered almost on a monthly basis, it is clear that a remarkable progress has been achieved in our understanding of the Galaxy, of its structure and stellar populations, and of its chemical and dynamical signatures. Yet, some questions
