The WHIQII Survey: Metallicities and Spectroscopic Properties of Luminous Compact Blue Galaxies (2009)

Tollerud, Erik J., Barton, Elizabeth J., Van Zee, Liese, Cooke, Jeff

As part of the WIYN High Image Quality Indiana Irvine (WHIQII) survey, we present 123 spectra of emission-line galaxies, selected on intermediate redshift (.4

Mg II Absorption Characteristics of a Volume-Limited Sample of Galaxies at z ~ 0.1 (2009)

Barton, Elizabeth J., Cooke, Jeff

We present an initial survey of Mg II absorption characteristics in the halos of a carefully constructed, volume-limited subsample of galaxies embedded in the spectroscopic part of the Sloan Digital...

Broadband Imaging Segregation of z ~ 3 Ly-alpha Emitting and Ly-alpha Absorbing Galaxies (2009)

Cooke, Jeff

The spectral properties of Lyman break galaxies (LBGs) offer a means to isolate pure samples displaying either dominant Ly-alpha in absorption or Ly-alpha in emission using broadband information...

Deep Keck u-band imaging of the Hubble Ultra Deep Field: A catalog of z~3 Lyman Break Galaxies (2009)

Rafelski, Marc, Wolfe, Arthur M., Cooke, Jeff, Chen, Hsiao-Wen, Armandroff, Taft E., Wirth, Gregory D.

We present a sample of 407 z~3 Lyman break galaxies (LBGs) to a limiting isophotal u-band magnitude of 27.6 mag in the Hubble Ultra Deep Field (UDF). The LBGs are selected using a combination of...

First Light Sources at the End of the Dark Ages: Direct Observations of Population III Stars, Proto-Galaxies, and Supernovae During the Reionization Epoch (2009)

Cooke, Jeff, Cooray, Asantha, Chary, Ranga-Ram, Bromm, Volker, Cen, Renyue, Ellis, Richard, ...

The cosmic dark ages are the mysterious epoch during which the pristine gas began to condense and ultimately form the first stars. Although these beginnings have long been a topic of theoretical...

A Candidate Brightest Proto-Cluster Galaxy at z = 3.03 (2008)

Cooke, Jeff, Barton, Elizabeth J., Bullock, James S., Stewart, Kyle R., Wolfe, Arthur M.

We report the discovery of a very bright (m_R = 22.2) Lyman break galaxy at z = 3.03 that appears to be a massive system in a late stage of merging. Deep imaging reveals multiple peaks in the...

TITLE ASP Conference Series, Vol. VOLUME, YEAR EDITORS EXPORT: Search for Transits in Open Clusters with the JKT and Lick 1 m Telescopes (2007)

Andreas Quirrenbach, Jeff Cooke, David Mitchell, Neda Safizadeh, Hans Deeg

EXPORT team Abstract. A photometric search for transits by extrasolar planets in three open clusters has been carried out as part of the EXPORT project. We discuss the rationale for this program,...

Detecting z > 2 Type IIn Supernovae (2007)

Cooke, Jeff

Type IIn supernovae (SNe IIn) dominate the brightest supernova events in observed FUV flux (~1200-2000A). We show that multi-band, multi-epoch optical surveys complete to m_r = 27 can detect the FUV...

The Ucsd/Keck Damped Lya Abundance Database: A Decade of High Resolution Spectroscopy (2007)

Prochaska, Jason X., Wolfe, Arthur M., Howk, J. Christopher, Gawiser, Eric, Burles, Scott M., Cooke, Jeff

We publish the Keck/HIRES and Keck/ESI spectra that we have obtained during the first 10 years of Keck observatory operations. Our full sample includes 42 HIRES spectra and 39 ESI spectra along 65...

Survey for Galaxies Associated with z~3 Damped Lyman alpha Systems II: Galaxy-Absorber Correlation Functions (2006)

Cooke, Jeff, Wolfe, Arthur M., Gawiser, Eric, Prochaska, Jason X.

We use 211 galaxy spectra from our survey for Lyman break galaxies (LBGs) associated with 11 damped Lyman alpha systems (DLAs) to measure the three-dimensional LBG auto-correlation and DLA-LBG...

The UCSD Radio-Selected Quasar Survey for Damped Lyman alpha System (2006)

Jorgenson, Regina A., Wolfe, Arthur M., Prochaska, Jason X., Lu, Limin, Howk, J. Christopher, Cooke, Jeff, ...

As large optical quasar surveys for damped Lya become a reality and the study of star forming gas in the early Universe achieves statistical robustness, it is now vital to identify and quantify the...

The ESI/KeckII Damped Lya Abundance Database (2003)

Prochaska, Jason X., Gawiser, Eric, Wolfe, Arthur M., Cooke, Jeff, Gelino, Dawn

This paper presents chemical abundance measurements for 37 damped Lya systems at z>2.5 observed with the Echellette Spectrograph and Imager on the KeckII telescope. We measure the HI column densities...

Galaxies Associated with z~4 Damped Lya Systems: I. Imaging and Photometric Selection (2002)

Prochaska, Jason X., Gawiser, Eric, Wolfe, Arthur M., Quirrenbach, Andreas, Lanzetta, Kenneth M., Chen, Hsiao-Wen, ...

This paper describes the acquisition and analysis of imaging data for the identification of galaxies associated with z~4 damped Lya systems. We present deep BRI images of three fields known to...

The UCSD HIRES/KeckI Damped Lya Abundance Database: I. The Data (2001)

Prochaska, Jason X., Wolfe, Arthur M., Tytler, David, Burles, Scott, Cooke, Jeff, Gawiser, Eric, ...

We present new chemical abundance measurements of 16 damped Lya systems at z>1.5 and update our previous abundance analyses. The entire database presented here was derived from HIRES observations on...
