TL;DR: A database of parameters for globular star clusters in the Milky Way is described which is available in electronic form through the WorldWideWeb as discussed by the authors. The information in the catalog includes up-to-date measurements for cluster distance, reddening, luminosity, colors and spectral types, velocity, structural and dynamical parameters, horizontal branch morphology, metallicity, and other quantities.

TL;DR: A panorama of galaxy structure of the Andromeda galaxy (M31) is reported, which directly confirms the basic tenets of the hierarchical galaxy formation model and reveals the shared history of M31 and M33 in the unceasing build-up of galaxies.

TL;DR: Luminosity functions, color gradients and metallicities of extragalactic globular clusters are reviewed in this paper, where the luminosity function, color gradient, and metallicity of clusters are compared.

TL;DR: In this article, the authors examined the maximum bolometric peak luminosities during type I X-ray bursts from the persistent or transient luminous Xray sources in globular clusters.
