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…
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…
SHM: A Refinement of the Standard Halo Model for Dark Matter Searches in Light of the Gaia Sausage
N. Wyn Evans, Ciaran A. J. O'Hare, Christopher McCabe
Predicting signals in experiments to directly detect dark matter (DM) requires a form for the local DM velocity distribution. Hitherto, the standard halo model (SHM), in which velo…
SDSS J09094449: A Large-separation Strongly Lensed Quasar at with Three Images
Yiping Shu, Rui Marques-Chaves, N. Wyn Evans +1
We report the discovery of SDSS J09094449, an exceptional system consisting of a quasar at strongly lensed by a group of galaxies at into three images sep…
Microlens mass determination for Gaia's predicted photometric events
Peter McGill, Leigh C. Smith, N. Wyn Evans +2
We used Gaia Data Release 2 to search for upcoming photometric microlensing events, identifying two candidates with high amplification. In the case of candidate 1, a spectrum of th…
