Probing $\sim L_{*}$ Lyman-break Galaxies at $z\approx 7$ in GOODS-South with WFC3 on HST (2009)
Wilkins, Stephen M., Bunker, Andrew J., Ellis, Richard S., Stark, Daniel, Stanway, Elizabeth R., Chiu, Kuenley, ...
We analyse recently acquired near-infrared Hubble Space Telescope imaging of the GOODS-South field to search for star forming galaxies at z~7.0. By comparing WFC 3 0.98 micron Y-band images with ACS...
Leonard, Adrienne, King, Lindsay J., Wilkins, Stephen M.
Gravitational flexion has recently been introduced as a technique by which one can map out and study substructure in clusters of galaxies. Previous analyses involving flexion have measured the...
Extragalactic Constraints on the Initial Mass Function (2008)
Wilkins, Stephen M., Hopkins, Andrew M., Trentham, Neil, Tojeiro, Rita
The local stellar mass density is observed to be significantly lower than the value obtained from integrating the cosmic star formation history (SFH), assuming that all the stars formed with a...
The Evolution of Stellar Mass and the Implied Star Formation History (2008)
Wilkins, Stephen M., Trentham, Neil, Hopkins, Andrew M.
We present a compilation of measurements of the stellar mass density as a function of redshift. Using this stellar mass history we obtain a star formation history and compare it to the instantaneous...
