Chemodynamics of metal-poor wide binaries in the Galactic halo: Association with the Sequoia event

Dongwook Lim, Andreas J. Koch-Hansen, Camilla Juul Hansen +4

Recently, an increasing number of wide binaries has been discovered. Their chemical and dynamical properties are studied through extensive surveys and pointed observations. However…

Breaking Beta: A comparison of mass modelling methods for spherical systems

J. I. Read, G. A. Mamon, E. Vasiliev +6

We apply four different mass modelling methods to a suite of publicly available mock data for spherical stellar systems. We focus on the recovery of the density and velocity anisot…

Reliable mass calculation in spherical gravitating systems

Foivos I. Diakogiannis, Geraint F. Lewis, Rodrigo A. Ibata +3

We present an innovative approach to the methodology of dynamical modelling, allowing practical reconstruction of the underlying dark matter mass without assuming both the density…

Dynamical modelling of dwarf-spheroidal galaxies using Gaussian-process emulation

Amery Gration, Mark I. Wilkinson

We present a novel and efficient method for fitting dynamical models of stellar kinematic data in dwarf spheroidal galaxies (dSph). Our approach is based on Gaussian-process emulat…

Gaia Radial Velocity Spectrometer

M. Cropper, D. Katz, P. Sartoretti +40

This paper presents the specification, design, and development of the Radial Velocity Spectrometer (RVS) on the European Space Agency's Gaia mission. Starting with the rationale fo…

A novel JEAnS analysis of the Fornax dwarf using evolutionary algorithms: mass follows light with signs of an off-centre merger

Foivos I. Diakogiannis, Geraint F. Lewis, Rodrigo A. Ibata +4

Dwarf galaxies, among the most dark matter dominated structures of our universe, are excellent test-beds for dark matter theories. Unfortunately, mass modelling of these systems su…
