cds-question@unistra.frgalaxiesglobular-star-clustersradial-velocityWe 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{deg} away from the center of the galaxy. We obtained low resolution spectra ({lambda}/{Delta}{lambda}~800-1300) of 48 targets selected from the Extended Source Catalogue of 2MASS, as in Galleti et al. (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).2007A&A...471..127Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/471/127CatalogResearchIsServedByTAP VizieR generic serviceIsPreviousVersionOfV/143IsServedByConesearch servicerelated-toJ/A+A/416/917 : Revised Bologna Catalog of M31 globular cluster (Galleti+ 2004)J/A+AS/116/447 : M31 globulars clusters ellipticities (Staneva+, 1996)J/AcA/48/455 : Globular Clusters in M31 and M33 (Mochejska+, 1998)J/AJ/119/727 : M31 globular clusters photometry (Barmby+, 2000)J/AJ/122/2458 : M31 globular clusters from HST (Barmby+, 2001)J/A+A/449/143 : Photometry of M31 globular cluster candidates (Ma+, 2006)J/A+A/456/985 : Radial velocities of 76 M31 candidate clusters (Galleti+, 2006)http://www.bo.astro.it/M31 : M31 Globular Clusters Home PageV/143 : Revised Bologna Catalog of M31 clusters, V.5 (Galleti+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/471/127https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/471/127http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/471/127https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/471/127https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/471/127http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/471/127GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/471/127/m31rbc (Revised Bologna Catalog of M31 globular clusters and candidates: RBC V3.5 (Version March, 2008))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/471/127/m31rbc?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/471/127/m31rbc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/471/127/m31rbc?GETtext/xml+votable180.050000true9.962487540.96958330.0055555555555555565/653 655 666 676-677 6/2567 2578 2589 2591 2597-2599 2602 2605-2607 2610-2611 2616-2617 2619 2624 2635 2637 2656-2657 2660 2662-2663 2668 2672 2674 2681 2686 2689 2692-2693 2695 2698 2701 2712-2714 2716 2719 2728 2752-2753 2755-2757 2759 2761-2762 2789 2810 2865 204337.952274030004205e-20 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/471/127?format=asciiOpticaldefaultJ/A+A/471/127/m31rbcRevised Bologna Catalog of M31 globular clusters and candidates: RBC V3.5 (Version March, 2008)recnoRecord number assigned by the VizieR team.
