The Pristine Inner Galaxy Survey (PIGS) VIII: Characterising the orbital properties of the ancient, very metal-poor inner Milky Way
Anke Ardern-Arentsen, Giacomo Monari, Anna B. A. Queiroz +19
The oldest stars in the Milky Way (born in the first few billion years) are expected to have a high density in the inner few kpc, spatially overlapping with the Galactic bulge. We…
NANCY: Next-generation All-sky Near-infrared Community surveY
Jiwon Jesse Han, Arjun Dey, Adrian M. Price-Whelan +206
The Nancy Grace Roman Space Telescope is capable of delivering an unprecedented all-sky, high-spatial resolution, multi-epoch infrared map to the astronomical community. This oppor…
Peeking beneath the precision floor -- II. Probing the chemo-dynamical histories of the potential globular cluster siblings, NGC 288 and NGC 362
Stephanie Monty, David Yong, Davide Massari +8
The assembly history of the Milky Way (MW) is a rapidly evolving subject, with numerous small accretion events and at least one major merger proposed in the MW's history. Accreted…
Milky Way's eccentric constituents with , APOGEE GALAH
G. C. Myeong, Vasily Belokurov, David S. Aguado +3
We report the results of an unsupervised decomposition of the local stellar halo in the chemo-dynamical space spanned by the abundance measurements from APOGEE DR17 and GALAH DR3.…
Elevated r-process enrichment in Gaia Sausage and Sequoia
David S. Aguado, Vasily Belokurov, G. C. Myeong +6
The Gaia Sausage (GS) and the Sequoia represent the major accretion events that formed the stellar halo of the Milky Way. A detailed chemical study of these main building blocks pr…
Orbital Clustering Identifies the Origins of Galactic Stellar Streams
Ana Bonaca, Rohan P. Naidu, Charlie Conroy +9
The origins of most stellar streams in the Milky Way are unknown. With improved proper motions provided by Gaia EDR3, we show that the orbits of 23 Galactic stellar streams are hig…
The S2 Stream: the shreds of a primitive dwarf galaxy
David S. Aguado, G. C. Myeong, Vasily Belokurov +12
The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream. We…
Dynamical Relics of the Ancient Galactic Halo
Zhen Yuan, G. C. Myeong, Timothy C. Beers +11
We search for dynamical substructures in the LAMOST DR3 very metal-poor (VMP) star catalog. After cross-matching with Gaia DR2, there are 3300 VMP stars with available high-quality…
Dark Shards: velocity substructure from Gaia and direct searches for dark matter
Ciaran A. J. O'Hare, N. Wyn Evans, Christopher McCabe +2
Data from the Gaia satellite show that the solar neighbourhood of the Milky Way's stellar halo is imprinted with substructure from several accretion events. Evidence of these event…
Evidence for Two Early Accretion Events That Built the Milky Way Stellar Halo
G. C. Myeong, E. Vasiliev, G. Iorio +2
The Gaia Sausage is the major accretion event that built the stellar halo of the Milky Way galaxy. Here, we provide dynamical and chemical evidence for a second substantial accreti…
The Sausage Globular Clusters
G. C. Myeong, N. W. Evans, V. Belokurov +2
The Gaia Sausage is an elongated structure in velocity space discovered by Belokurov et al. (2018) using the kinematics of metal-rich halo stars. It was created by a massive dwarf…
A Dark Matter Hurricane: Measuring the S1 Stream with Dark Matter Detectors
Ciaran A. J. O'Hare, Christopher McCabe, N. Wyn Evans +2
The recently discovered S1 stream passes through the Solar neighbourhood on a low inclination, counter-rotating orbit. The progenitor of S1 is a dwarf galaxy with a total mass comp…
The Shards of Centauri
G. C. Myeong, N. W. Evans, V. Belokurov +2
We use the SDSS-Gaia catalogue to search for substructure in the stellar halo. The sample comprises 62\,133 halo stars with full phase space coordinates and extends out to heliocen…
The Milky Way Halo in Action Space
G. C. Myeong, N. W. Evans, V. Belokurov +2
We analyse the structure of the local stellar halo of the Milky Way using 60000 stars with full phase space coordinates extracted from the SDSS--{\it Gaia} catalogue. We dis…
Halo Substructure in the SDSS-Gaia Catalogue : Streams and Clumps
G. C. Myeong, N. W. Evans, V. Belokurov +2
We use the SDSS-Gaia Catalogue to identify six new pieces of halo substructure. SDSS-Gaia is an astrometric catalogue that exploits SDSS data release 9 to provide first epoch photo…
Tidal tails around the outer halo globular clusters Eridanus and Palomar 15
G. C. Myeong, Helmut Jerjen, Dougal Mackey +1
We report the discovery of tidal tails around the two outer halo globular clusters, Eridanus and Palomar 15, based on -band images obtained with DECam at the CTIO 4-m Blanco Te…
