Globular clusters as gravitational lenses
Listed in IVOA Registry (Virtual Observatory)
Based on the SDSS catalog, we have found new close quasar-galaxy pairs.
Description
We analyze the radial distribution of quasars from pairs around galaxies of different types. We show that the quasars from pairs follow the density profile of halo globular clusters.
This is new observational evidence that the quasars projected onto the halos of galaxies are magnified by gravitational lensing by halo globular clusters.
