  author={Arihiro Mizutani and Masashi Chiba and Tsuyoshi Sakamoto},
  journal={The Astrophysical Journal},
We present the kinematic properties of a tidally disrupted dwarf galaxy in the Milky Way, based on the hypothesis that its central part once contained the most massive Galactic globular cluster, ω Cen. Dynamical evolution of a self-gravitating progenitor galaxy that follows the present-day and likely past orbits of ω Cen is calculated numerically and the kinematic nature of their tidal debris is analyzed, combined with randomly generated stars comprising spheroidal halo and flat disk components… 
On the Kinematics of Tidal Debris from Omega Cen's Progenitor Galaxy
Abstract The kinematic properties of tidal debris from an orbiting Galactic satellite is presented, on the assumption that its central part once contained the most massive Galactic globular cluster,
Accretion relics in the solar neighbourhood : Debris from ωCen's parent galaxy
We use numerical simulations to investigate the orbital characteristics of tidal debris from satellites whose orbits are dragged into the plane of galact ic disks by dynamical friction before
Formation of ω Centauri from an ancient nucleated dwarf galaxy in the young Galactic disc
We first present a self-consistent dynamical model in which ω Cen is formed from an ancient nucleated dwarf galaxy merging with the first generation of the Galactic thin disc in a retrograde manner
Identification of the long stellar stream of the prototypical massive globular cluster ω Centauri
Omega Centauri (ω Cen) is the Milky Way’s most massive globular cluster, and has long been suspected of being the remnant core of an accreted dwarf galaxy. If this scenario is correct, ω Cen should
A New Formation Model for ω Centauri: A Complex Interplay of Astrophysical Processes
We investigate the formation processes of the Galactic globular cluster (GC) omega Cen with multiple stellar populations based on our original hydrodynamical simulations with chemical enrichment by
The Disk and Extraplanar Environment of NGC 247
The stellar content of the spiral galaxy NGC 247 is investigated using deep visible and near-infrared images. The main-sequence turnoff (MSTO) in the inner 12 kpc of the disk corresponds to an age of
Exploring Halo Substructure with Giant Stars: Substructure in the Local Halo as Seen in the Grid Giant Star Survey Including Extended Tidal Debris from Omega Centauri
We present the latitude-normalized radial velocity (vb) distribution of 3318 subsolar metallicity, V<13.5 stars from the Grid Giant Star Survey (GGSS) in Southern Hemisphere fields. The sample
Tracing the formation of the Milky Way through ultra metal-poor stars
We use Gaia DR2 astrometric and photometric data, published radial velocities and MESA models to infer distances, orbits, surface gravities, and effective temperatures for all ultra metal-poor stars
Searching for merger debris in the Galactic halo: chemodynamical evidence based on local blue HB stars
We report on the discovery of a group of local A-type blue horizontal-branch (HBA) stars moving in a prograde, comet-like orbit with very similar kinematics and abundances. This serendipitously
Searching for tidal tails around ω Centauri using RR Lyrae stars
We present a survey for RR Lyrae stars in an area of 50 deg$^2$ around the globular cluster $\omega$ Centauri, aimed to detect debris material from the alleged progenitor galaxy of the cluster. We


Formation of Galactic Disk Globular Clusters in Early Dissipative Minor Merging
The origin of metal-rich, highly flattened, and rapidly rotating disk globular cluster systems in the Galaxy is one of long-standing issues in the context of the Galaxy formation. Our numerical
Evidence for the Hierarchical Formation of the Galactic Spheroid
The possibility that the Galactic spheroid was assembled from isolated, chemically distinct proto- Galactic fragments is investigated using a Monte Carlo technique designed to simulate the chemical
Deciphering the Last Major Invasion of the Milky Way
We present first results from a spectroscopic survey of ~2000 F/G stars 0.5-5 kpc from the Galactic plane, obtained with the Two Degree Field facility on the Anglo-Australian Telescope. These data
Space Velocities of Globular Clusters. III. Cluster Orbits and Halo Substructure
We have compiled a catalog of absolute proper motions of globular clusters from various sources. The sample consists of 38 clusters, from which most of the southern ones (15 clusters) were measured
Kinematics of Metal-poor Stars in the Galaxy. III. Formation of the Stellar Halo and Thick Disk as Revealed from a Large Sample of Nonkinematically Selected Stars
We present a detailed analysis of the space motions of 1203 solar-neighborhood stars with metal abundances [Fe/H] ≤ -0.6, on the basis of a catalog, of metal-poor stars selected without kinematic

We present a revised catalog of 2106 Galactic stars, selected without kinematic bias and with available radial velocities, distance estimates, and metal abundances in the range -4.0 ≤ [Fe/H] ≤ 0.0.
The Unique History of the Globular Cluster ω Centauri
Using current observational data and simple dynamical modeling, we demonstrate that ω Cen is not special among the Galactic globular clusters in its ability to produce and retain the heavy elements
▪ Abstract The Local Group dwarf galaxies offer a unique window to the detailed properties of the most common type of galaxy in the Universe. In this review, I update the census of Local Group dwarfs
