Competitive feedback in galaxy formation (2009)
Nayakshin, Sergei, Wilkinson, Mark I., King, Andrew
It is now well established that many galaxies have nuclear star clusters (NCs) whose total masses correlate with the velocity dispersion (sigma) of the galaxy spheroid in a very similar way to the...
The abundance spread in the Bootes I dwarf spheroidal galaxy (2009)
Norris, John E., Gilmore, Gerard, Wyse, Rosemary F. G., Wilkinson, Mark I., Belokurov, V., Evans, N. Wyn, ...
We present medium-resolution spectra of 16 radial velocity red-giant members of the low-luminosity Bootes I dwarf spheroidal (dSph) galaxy, that have sufficient S/N for abundance determination, based...
Kinematic sub-populations in dwarf spheroidal galaxies (2008)
Ural, Ugur, Wilkinson, Mark I., Koch, Andreas, Gilmore, Gerard, Beers, Timothy C., Belokurov, Vasily, ...
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 of the presence of...
The Observed properties of Dark Matter on small spatial scales (2007)
Gilmore, Gerard, Wilkinson, Mark I., Wyse, Rosemary F. G., Kleyna, Jan T., Koch, Andreas, Evans, N. Wyn
We present a synthesis of recent photometric and kinematic data for several of the most dark-matter dominated galaxies. There is a bimodal distribution in half-light radii, with stable star clusters...
Malmberg, Daniel, De Angeli, Francesca, Davies, Melvyn B., Church, Ross P., Mackey, Dougal, Wilkinson, Mark I.
The stars that populate the solar neighbourhood were formed in stellar clusters. Through N-body simulations of these clusters, we measure the rate of close encounters between stars. By monitoring the...
On the Origin of Dark Matter Cores in Dwarf Galaxies (2004)
Ricotti, Massimo, Wilkinson, Mark I.
In this paper, we study the dynamical stability and time evolution of the central dark matter cores of low-mass (about 10^8-10^9 M_solar) galactic haloes found in recent cold dark matter simulations...
Massive Black Holes in Dwarf Spheroidal Galaxy Haloes? (2003)
Jin, Shoko, Ostriker, Jeremiah P., Wilkinson, Mark I.
It is now established that several of the Local Group dwarf Spheroidal galaxies (dSphs) have large mass-to-light ratios. We consider the possibility that the dark matter in the halos of dSphs is...
Core radius evolution of star clusters (2003)
Wilkinson, Mark I., Hurley, Jarrod R., Mackey, A. Dougal, Gilmore, Gerard F., Tout, Christopher A.
We use N-body simulations of star clusters to investigate the possible dynamical origins of the observed spread in core radius among intermediate-age and old star clusters in the Large Magellanic...
A Dynamical Fossil in the Ursa Minor Dwarf Spheroidal Galaxy (2003)
Kleyna, Jan T., Wilkinson, Mark I., Gilmore, Gerard, Evans, N. Wyn
The nearby Ursa Minor dwarf spheroidal (UMi dSph) is one of the most dark matter dominated galaxies known, with a central mass to light ratio roughly equal to 70. Somewhat anomalously, it appears to...
Core evolution of rich stellar clusters in the LMC (2003)
Mackey, A. Dougal, Wilkinson, Mark I., Gilmore, Gerry F., Hurley, Jarrod R.
Observations of rich LMC clusters reveal an increasing spread in core radius with increasing age. We use N-body simulations of clusters on elliptical orbits about the LMC to show that a time-varying...
