We show that there is a subsystem of the M31 globular clusters with thin-disk kinematics. These clusters span the entire metallicity range of the M31 globular cluster system, in contrast to the (thick) disk globular clusters in the Milky Way, which are predominantly metal-rich. Disk globular clusters are found across the entire disk of M31 and form � 40% of the clusters projected on its disk. The existence of such a disk system suggests that there was a relatively large thin disk in place very… Expand
Massive Young Clusters in the Disk of M31
We have studied the properties of a sample of 67 very blue and likely young massive clusters in M31 extracted from the Bologna Revised Catalog of globular clusters, selected according to their colorExpand
The bimodal metallicity distribution function of the globular clusters in the Galaxy: halo disc complementarity
Aims. Our aim in this paper is to present an explanatory scenario for the formation of the observed relatively metal rich globular clusters associated with the thick disc of the Galaxy, distinct fromExpand
Evidence for the Disky Origin of Luminous Virgo Dwarf Ellipticals from the Kinematics of Their Globular Cluster Systems
We report evidence for dynamically significant rotation in the globular cluster systems of two luminous Virgo dwarf ellipticals, VCC1261 and VCC1528. Including previous results for VCC1087, theExpand
Star Clusters in M31. II. Old Cluster Metallicities and Ages from Hectospec Data
We present new high signal-to-noise spectroscopic data on the M31 globular cluster (GC) system, obtained with the Hectospec multifiber spectrograph on the 6.5 m MMT. More than 300 clusters have beenExpand
The outermost cluster of M31
We report on the identification of a new cluster in the far halo of the M31 galaxy. The cluster, named Bologna 514 (B514) has an integrated magnitude M v = -8.5 ± 0.6, and a radial velocity, asExpand
Star Clusters in M31: VII. Global Kinematics and Metallicity Subpopulations of the Globular Clusters
We carry out a joint spatial-kinematical-metallicity analysis of globular clusters (GCs) around the Andromeda Galaxy (M31), using a homogeneous, high-quality spectroscopic dataset. In particular, weExpand
Globular Cluster and Galaxy formation: M31, The Milky Way, and Implications for Globular Cluster Systems of Spiral Galaxies
We find that the globular cluster (GC) systems of the Milky Way and of our neighboring spiral galaxy, M31, comprise two distinct entities, differing in three respects. First, M31 has a set of youngExpand
THE CHEMICAL PROPERTIES OF MILKY WAY AND M31 GLOBULAR CLUSTERS. II. STELLAR POPULATION MODEL PREDICTIONS
We derive ages, metallicities, and abundance ratios ([α/Fe]) from the integrated spectra of 23 globular clusters in M31 by employing multivariate fits to two different stellar population models. WeExpand
On the Accretion Origin of a Vast Extended Stellar Disk around the Andromeda Galaxy
We present the discovery of an inhomogenous, low surface brightness, extended disklike structure around the Andromeda galaxy (M31) based on a large kinematic survey of more than 2800 stars with theExpand
THE CHEMICAL PROPERTIES OF MILKY WAY AND M31 GLOBULAR CLUSTERS. I. A COMPARATIVE STUDY
A comparative analysis is performed between high-quality integrated spectral indices of 30 M31 globular clusters, 20 Milky Way globular clusters, and a sample of field and cluster ellipticalExpand
