High Inclination Planets in Multistellar Systems
P. E. Verrier, N. W. Evans
The Kozai mechanism often destabilises high inclination orbits. It couples changes in the eccentricity and inclination, and drives high inclination, circular orbits to low inclinat…
Superintegrability of the Caged Anisotropic Oscillator
N. W. Evans, P. E. Verrier
We study "the Caged Anisotropic Harmonic Oscillator", which is a new example of a superintegrable, or accidentally degenerate Hamiltonian. The potential is that of the harmonic osc…
Kinematic sub-populations in dwarf spheroidal galaxies
Ugur Ural, Mark I. Wilkinson, Andreas Koch +7
We present new spectroscopic data for twenty six stars in the recently-discovered Canes Venatici I (CVnI) dwarf spheroidal galaxy. We use these data to investigate the recent claim…
Two New Large Separation Gravitational Lenses from SDSS
V. Belokurov, N. W. Evans, P. C. Hewett +4
We present discovery images, together with follow-up imaging and spectroscopy, of two large separation gravitational lenses found by our survey for wide arcs (the CASSOWARY). The s…
What is a galaxy? How Cold is Cold Dark Matter? Recent progress in Near Field Cosmology
Gerard Gilmore, Dan Zucker, Mark Wilkinson +6
There has been a vast recent improvement in photometric and kinematic data for star clusters, Ultra Compact dwarfs, galactic nuclei, and local dSph galaxies, with Subaru contributi…
Models of the Cosmic Horseshoe Gravitational Lens
Simon Dye, N. W. Evans, V. Belokurov +2
We model the extremely massive and luminous lens galaxy in the Cosmic Horseshoe Einstein ring system, recently discovered in the Sloan Digital Sky Survey. We use the semi-linear me…
