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...
Bunker, Andrew, Wilkins, Stephen, Ellis, Richard, Stark, Daniel, Lorenzoni, Silvio, Chiu, Kuenley, ...
We have searched for star-forming galaxies at z~7 by applying the Lyman-break technique to newly-released 1.1micron Y-band images from WFC3 on HST. By comparing these images of the Hubble Ultra Deep...
Galaxies at High Redshift and Reionization (2009)
Bunker, Andrew, Stanway, Elizabeth, Ellis, Richard, Lacy, Mark, McMahon, Richard, Eyles, Laurence, ...
The quest to discover the most distant galaxies has developed rapidly in the last decade. We are now exploring redshifts of 6 and beyond, when the Universe was less than a billion years old, an epoch...
A statistical study of multiply-imaged systems in the lensing cluster Abell 68 (2007)
Richard, Johan, Kneib, Jean-Paul, Jullo, Eric, Covone, Giovanni, Limousin, Marceau, Ellis, Richard, ...
We have carried out an extensive spectroscopic survey with the Keck and VLT telescopes, targeting lensed galaxies in the background of the massive cluster Abell 68. Spectroscopic measurements are...
The Stellar Mass Density at z~6 from Spitzer Imaging of i-drop Galaxies (2006)
Eyles, Laurence, Bunker, Andrew, Ellis, Richard, Lacy, Mark, Stanway, Elizabeth, Stark, Daniel, ...
We measure the ages, stellar masses, and star formation histories of z~6 galaxies, observed within 1Gyr of the Big Bang. We use imaging from HST and Spitzer from the public "Great Observatories...
In situ product removal (ISPR) in whole cell biotechnology during the last twenty years (2003)
Stark, Daniel, Von Stockar, Urs
This review sums up the activity in the field of in situ product removal in whole cell bioprocesses over the last 20 yr. It gives a complete summary of ISPR operations with microbial cells and cites...
