The Aquarius Project: the subhaloes of galactic haloes
We have performed the largest ever particle simulation of a Milky Way sized dark matter halo, and present the most comprehensive convergence study for an individual dark matter halo carried out thus
Sloan digital sky survey: Early data release
The Sloan Digital Sky Survey (SDSS) is an imaging and spectroscopic survey that will eventually cover approximately one-quarter of the celestial sphere and collect spectra of ≈106 galaxies, 100,000
Gaia Data Release 2
Context. We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources brighter
Gaia Data Release 2
Context. The second Gaia data release (DR2) contains very precise astrometric and photometric properties for more than one billion sources, astrophysical parameters for dozens of millions, radial
The merger that led to the formation of the Milky Way’s inner stellar halo and thick disk
It is demonstrated that the inner halo of the Galaxy is dominated by debris from an object that at infall was slightly more massive than the Small Magellanic Cloud, and which the authors refer to as Gaia–Enceladus, which is in line with the results of galaxy formation simulations.
Euclid Definition Study Report
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to investigate the
The radial velocity dispersion profile of the Galactic halo : constraining the density profile of the dark halo of the Milky Way
We have compiled a new sample of 240 halo objects with accurate distance and radial velocity measurements, including globular clusters, satellite galaxies, field blue horizontal branch (FHB) stars
The RAVE survey: constraining the local Galactic escape speed
New constraints on the local escape speed of the Galaxy are reported, finding that the escape velocity lies within the range 498 <v(esc) <608 km s (-1) (90 per cent confidence), with a median likelihood of 544 km s(-1).
The diversity and similarity of simulated cold dark matter haloes
We study the mass, velocity dispersion and anisotropy profiles of Lambda cold dark matter (Lambda CDM) haloes using a suite of N-body simulations of unprecedented numerical resolution. The Aquarius
