The Highly Unusual Chemical Composition of the Hercules Dwarf Spheroidal Galaxy (2008)
Koch, A., McWilliam, A., Grebel, E. K., Zucker, D. B, Belokurov, V.
We report on the abundance analysis of two red giants in the faint Hercules dwarf spheroidal (dSph) galaxy. These stars show a remarkable deficiency in the neutron-capture elements, while the...
Schoerck, T., Christlieb, N., Cohen, J. G., Beers, T. C., Shectman, S., Thompson, I., ...
We determine the metallicity distribution function (MDF) of the Galactic halo by means of a sample of 1638 metal-poor stars selected from the Hamburg/ESO objective-prism survey (HES). The sample was...
The chemical evolution of Manganese in different stellar systems (2008)

Aims. To model the chemical evolution of manganese relative to iron in three different stellar systems: the solar neighbourhood, the Galactic bulge and the Sagittarius dwarf spheroidal galaxy, and...
An Update on the 0Z Project (2007)
Cohen, J. G., Christlieb, N., McWilliam, A., Shectman, S., Thompson, I.
We give an update on our 0Z Survey to find more extremely metal poor (EMP) stars with [Fe/H] < -3 dex through mining the database of the Hamburg/ESO Survey. We present the most extreme such stars we...
The Evolution of Oxygen and Magnesium in the Bulge and Disk of the Milky Way (2007)
McWilliam, A., Matteucci, F., Ballero, S., Rich, R. M., Fulbright, J. P., Cescutti, G.
We show that the Galactic bulge and disk share a similar, strong, decline in [O/Mg] ratio with [Mg/H]. The similarity of the [O/Mg] trend in these two, markedly different, populations suggests a...
Detailed Chemical Abundances of Extragalactic Globular Clusters (2005)
Bernstein, R. A., McWilliam, A.
We outline a method to measure the detailed chemical composition of extragalactic (unresolved) globular clusters (GCs) from echelle spectra of their integrated light. Our goal is to use this method...
Femtosecond Cr:Forsterite laser modelocked with a GaInNAs saturable Bragg reflector (2005)
McWilliam, A., Leburn, C.G., Lagatsky, A.A., Brown, C.T.A., Sibbett, W., Valentine, G.J., ...
A low loss GaInNAs saturable Bragg reflector has been used to generate picosecond and femtosecond pulses from a Cr:Forsterite laser operating in the 1300nm sperctral region.
