Abstract / Description of output
We report the discovery of 40 new globular clusters (GCs) that have been
found in surveys of the halo of M31 based on the Isaac Newton
Telescope/Wide-Field Camera and Canada-France-Hawaii Telescope/Megacam
imagery. A subset of these new GCs are of an extended, diffuse nature
and include those already found in Huxor et al. The search strategy is
described and basic positional and V and I photometric data are
presented for each cluster. For a subset of these clusters, K-band
photometry is also given. The new clusters continue to be found to the
limit of the survey area (~100 kpc), revealing that the GC system of M31
is much more extended than previously realized. The new clusters
increase the total number of confirmed GCs in M31 by approximately 10
per cent and the number of confirmed GCs beyond 1° (~14 kpc) by more
than 75 per cent. We have also used the survey imagery as well recent
Hubble Space Telescope archival data to update the Revised Bologna
Catalogue of M31 globular clusters.
