Is there substructure around M87?
L. J. Oldham, N. W. Evans
We present a general method to identify infalling substructure in discrete datasets with position and line-of-sight velocity data. We exploit the fact that galaxies falling onto a…
The Gaia-ESO survey: Metal-rich bananas in the bulge
Angus A. Williams, N. W. Evans, Matthew Molloy +25
We analyse the kinematics of giant stars in the direction of the Galactic bulge, extracted from the Gaia-ESO survey in the region $-10^\circ \lesssim \ell \lesssim 10^\…
Is the Dark Halo of the Milky Way Prolate?
A. Bowden, N. W. Evans, A. A. Williams
We introduce the flattening equation, which relates the shape of the dark halo to the angular velocity dispersions and the density of a tracer population of stars. It assumes spher…
Discy dwarf disruption and the shape of the Galactic halo
S. L. J. Gibbons, V. Belokurov, D. Erkal +1
The shape of the Galactic dark halo can, in principle, be inferred through modelling of stellar tidal streams in the Milky Way halo. The brightest and the longest of these, the Sag…
