Journal Article
Kegerreis, J. A., Eke, V. R., Massey, R. J., Beaumont, S. K., Elphic, R. C., & Teodoro, L. F. (2017). Evidence for a Localized Source of the Argon in the Lunar Exosphere. Journal of Geophysical Research: Planets, 122(10), 2163-2181. https://doi.org/10.1002/2017je005352

We perform the first tests of various proposed explanations for observed features of the Moon's argon exosphere, including models of the following: spatially varying surface interactions; a source that reflects the lunar near-surface potassium distri...

Equatorial locations of water on Mars: Improved resolution maps based on Mars Odyssey Neutron Spectrometer data (2017)
Journal Article
Wilson, J. T., Eke, V. R., Massey, R. J., Elphic, R. C., Feldman, W. C., Maurice, S., & Teodoro, L. F. (2018). Equatorial locations of water on Mars: Improved resolution maps based on Mars Odyssey Neutron Spectrometer data. Icarus, 299, 148-160. https://doi.org/10.1016/j.icarus.2017.07.028

We present a map of the near subsurface hydrogen distribution on Mars, based on epithermal neutron data from the Mars Odyssey Neutron Spectrometer. The map’s spatial resolution is approximately improved two-fold via a new form of the pixon image reco...

Knowing the unknowns: uncertainties in simple estimators of galactic dynamical masses (2017)
Journal Article
Campbell, D. J., Frenk, C. S., Jenkins, A., Eke, V. R., Navarro, J. F., Sawala, T., …Theuns, T. (2017). Knowing the unknowns: uncertainties in simple estimators of galactic dynamical masses. Monthly Notices of the Royal Astronomical Society, 469(2), 2335-2360. https://doi.org/10.1093/mnras/stx975

The observed stellar kinematics of dispersion-supported galaxies are often used to measure dynamical masses. Recently, several analytical relationships between the stellar line-of-sight velocity dispersion, the projected (2D) or deprojected (3D) half...

Cosmic particle colliders: simulations of self-interacting dark matter with anisotropic scattering (2017)
Journal Article
Robertson, A., Massey, R., & Eke, V. (2017). Cosmic particle colliders: simulations of self-interacting dark matter with anisotropic scattering. Monthly Notices of the Royal Astronomical Society, 467(4), 4719-4730. https://doi.org/10.1093/mnras/stx463

We investigate how self-interacting dark matter (SIDM) with anisotropic scattering affects the evolution of isolated dark matter haloes as well as systems with two colliding haloes. For isolated haloes, we find that the evolution can be adequately ca... Read More about Cosmic particle colliders: simulations of self-interacting dark matter with anisotropic scattering.
