Data Engineering for Data Analytics: A Classification of the Issues, and Case Studies
Alfredo Nazabal, Christopher K. I. Williams, Giovanni Colavizza +2
Consider the situation where a data analyst wishes to carry out an analysis on a given dataset. It is widely recognized that most of the analyst's time will be taken up with \emph{…
The Gaia-ESO Survey: Dynamical models of flattened, rotating globular clusters
Sarah M. R. Jeffreson, Jason L. Sanders, N. W. Evans +12
We present a family of self-consistent axisymmetric rotating globular cluster models which are fitted to spectroscopic data for NGC 362, NGC 1851, NGC 2808, NGC 4372, NGC 5927 and…
On the Run: mapping the escape speed across the Galaxy with SDSS
Angus A. Williams, Vasily Belokurov, Andrew R. Casey +1
We measure the variation of the escape speed of the Galaxy across a range of 40 kpc in Galactocentric radius. The local escape speed is found to be $521^{+46}_{-30}\,\mathrm…
Characterizing stellar halo populations II: The age gradient in blue horizontal-branch stars
Payel Das, Angus Williams, James Binney
The distribution of Milky Way halo blue horizontal-branch (BHB) stars is examined using action-based extended distribution functions (EDFs) that describe the locations of stars in…
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^\…
