Identification and photometry of globular clusters in M31 and M33 galaxies

摘要

We have used the data from the DIRECT project to search for new globularcluster candidates in the M31 and M33 galaxies. We have found 67 new objects inM31 and 35 in M33 and confirmed 38 and 16 previously discovered ones. A $VI$and $BVI$ photometry has been obtained for all the clusters in M31 and M33respectively. Luminosity functions have been constructed for the clusters ineach galaxy and compared with that of the Milky Way.
