Galaxy Clusters in Formation: Determining the Age of the Red-Sequence in Optical and X-ray Clusters at z~1 with HST (2009)

Koester, Benjamin P., Gladders, Michael D., Gilbank, David G., Yee, H. K. C., Barbary, Kyle, Dawson, Kyle S., ...

Using deep two-band imaging from the Hubble Space Telescope, we measure the color-magnitude relations (CMR) of E/S0 galaxies in a set of 9 optically-selected clusters principally from the...

The XMM Cluster Survey: Galaxy Morphologies and the Color-Magnitude Relation in XMMXCS J2215.9-1738 at z=1.46 (2009)

Hilton, Matt, Stanford, S. Adam, Stott, John P., Collins, Chris A., Hoyle, Ben, Davidson, Michael, ...

We present a study of the morphological fractions and color-magnitude relation in the most distant X-ray selected galaxy cluster currently known, XMMXCS J2215.9-1738 at z=1.46, using a combination of...

The XMM Cluster Survey: The Dynamical State of XMMXCS J2215.9-1738 at z=1.457 (2007)

Hilton, Matt, Collins, Chris A., Stanford, S. Adam, Lidman, Chris, Dawson, Kyle S., Davidson, Michael, ...

We present new spectroscopic observations of the most distant X-ray selected galaxy cluster currently known, XMMXCS J2215.9-1738 at z=1.457, obtained with the DEIMOS instrument at the W. M. Keck...

High-voltage-compatible, fully depleted CCDs (2006)

Holland, Stephen E., Bebek, Chris J., Dawson, Kyle S., Emes, John E., Fabricius, Max H., Fairfield, Jessaym A., ...

We describe charge-coupled device (CCD) development activities at the Lawrence Berkeley National Laboratory (LBNL). Back-illuminated CCDs fabricated on 200-300 mu m thick, fully depleted,...
