Description
We argue that globular clusters (GCs) are good candidates for gravitational lenses in explaining quasar-galaxy associations. The catalog of associations (Bukhmastova, 2001, Cat. <J/AZh/78/675>) compiled from the LEDA catalog of galaxies (Paturel, 1997A&AS..124..109P) and from the catalog of quasars (Veron-Cetty and Vero, 1998, see Cat. <VII/235>) is used. Based on the new catalog, we show that one might expect an increased number of GCs around irregular galaxies of types 9 and 10 from the hypothesis that distant compact sources are gravitationally lensed by GCs in the halos of foreground galaxies. The King model is used to determine the central surface densities of 135 GCs in the Milky Way. The distribution of GCs in central surface density was found to be lognormal.
