The total mass of the Large Magellanic Cloud from its perturbation on the Orphan stream
D. Erkal, V. Belokurov, C. F. P. Laporte +13
In a companion paper by Koposov et al., RR Lyrae from \textit{Gaia} Data Release 2 are used to demonstrate that stars in the Orphan stream have velocity vectors significantly misal…
Piercing the Milky Way: an all-sky view of the Orphan Stream
S. E. Koposov, V. Belokurov, T. S. Li +13
We use astrometry, broad-band photometry and variability information from the Data Release 2 of ESA's Gaia mission (GDR2) to identify members of the Orphan Stream (OS) across the w…
Stellar streams around the Magellanic Clouds in 4D
Camila Navarrete, Vasily Belokurov, Márcio Catelan +7
We carried out a spectroscopic follow-up program of the four new stellar stream candidates detected by Belokurov & Koposov (2016) in the outskirts of the Large Magellanic Cloud (LM…
Discovery of a disrupting open cluster far into the Milky Way halo: a recent star formation event in the leading arm of the Magellanic stream?
Adrian M. Price-Whelan, David L. Nidever, Yumi Choi +4
We report the discovery of a young (), low-mass (), metal-poor () stellar association at a he…
The hidden giant: discovery of an enormous Galactic dwarf satellite in Gaia DR2
G. Torrealba, V. Belokurov, S. E. Koposov +8
We report the discovery of a Milky Way satellite in the constellation of Antlia. The Antlia 2 dwarf galaxy is located behind the Galactic disc at a latitude of a…
The morphology and structure of stellar populations in the Fornax dwarf spheroidal galaxy from Dark Energy Survey Data
Mei-Yu Wang, T. de Boer, A. Pieres +55
Using deep wide-field photometry three-year data (Y3) from the Dark Energy Survey (DES), we present a panoramic study of the Fornax dwarf spheroidal galaxy. The data presented here…
