Abstract:
We present the first results of a large spectroscopic survey of
candidate globular clusters located in the extreme outskirts of the
nearby M 31 galaxy. The survey is aimed at ascertaining the nature of
the selected candidates to increase the sample of confirmed M 31
clusters lying more that 2° away from the center of the galaxy.
We obtained low resolution spectra (λ/Δλ∼800-1300)
of 48 targets selected from the Extended Source Catalogue of 2MASS, as
in Galleti et al. (2005A&A...436..535G 2005A&A...436..535G). The observed candidates have
been robustly classified according to their radial velocity and by
verifying their extended/point-source nature from ground-based optical
images. We have also obtained a spectrum and a radial velocity
estimate for the remote M 31 globular discovered by Martin et al.
(2006MNRAS.371.1983M 2006MNRAS.371.1983M).
Description:
The imager/spectrograph DoLoRes at the 3.52m TNG telescope in La
Palma (Canary Island, Spain) was used in service mode in various
nights during the period October-December, 2005 (Run 1), and in
visitor mode in the nights of October 10-15, 2006 (Run 2), to acquire
long slit spectra of 38 M 31 CGCs.
Long slit spectra for 16 CGCs in M 31 were obtained with the low
resolution spectrograph BFOSC mounted at the 1.52m Cassini Telescope
of the Loiano Observatory, near Bologna (Italy), during several runs
in 2006: August 19-22 (Run 1), September 1-2 (Run 2), October 25-27
(Run 3), and November 22-23 (Run 4).
