Near-Gaussian distributions for modelling discrete stellar velocity data with heteroskedastic uncertainties
Jason L. Sanders, N. Wyn Evans
The velocity distributions of stellar tracers in general exhibit weak non-Gaussianity encoding information on the orbital composition of a galaxy and the underlying potential. The…
Magellanic Mayhem: Metallicities and Motions
J. Grady, V. Belokurov, N. W. Evans
We assemble a catalogue of Magellanic Cloud red giants from Data Release 2 of the mission and, utilising machine learning methods, obtain photometric metallicity estimates f…
The S2 Stream: the shreds of a primitive dwarf galaxy
David S. Aguado, G. C. Myeong, Vasily Belokurov +12
The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream. We…
Binary deviations from single object astrometry
Zephyr Penoyre, Vasily Belokurov, N. Wyn Evans +2
Most binaries are undetected. Astrometric reductions of a system using the assumption that the object moves like a single point mass can be biased by unresolved binary stars. The d…
