Since the spring of 2002, I have been working as part of the DEEP2 team at UCB on the development of a DEIMOS data reduction pipeline and on the general design and implementation of the survey. Over the past 3+ years, the DEEP2 survey has utilized the new DEIMOS spectrograph on the Keck II telescope to target ~50,000 galaxies at redshifts 0.7 < z < 1.4 with the goal of studying the evolution of galaxy clustering and galaxy properties at z ~ 1. For more on the DEEP2 survey, visit the project website here.
The Team Keck Redshift Survey includes extensive an imaging and spectroscopic survey within the GOODS-North field. The survey was completed in the Spring of 2003 using the DEIMOS instrument on the Keck II telescope. The survey includes confirmed (by eye) spectroscopic redshifts for 1440 galaxies and 96 stars in the field, with a median redshift of z = 0.65. Details of the survey and data sample are provided in Wirth et al. 2004; the survey catalogs and spectra are also available for download from the TKRS website. My current interests in the GOODS-N field relate to studying the role of AGN (selected using X-ray source catalogs and optical emission-line diagnostics) in quenching star formation and relate to studying the morphology-density relation down to faint optical luminosities.
AEGIS is a large collaboration between many survey teams and institutions with the goal of sharing data in order to carry out multi-wavelength studies of sources in the Extended Groth Strip (EGS). The teams involved in the project include: The DEEP2 Galaxy Redshift Survey team, the GALEX team, the Spitzer IRAC/MIPS teams, the POWIR team, and the CFHT Legacy Survey. The combined data set in the field includes 21cm and 6cm radio maps from the VLA, deep IRAC and MIPS imaging, optical BRI imaging from CFH (DEEP2), even deeper optical imaging as part of CFHTLS, extremely deep GALEX imaging, near-IR imaging using WIRC at Palomar, 1.6 mega-seconds of Chandra/ACIS imaging, HST/ACS V,I imaging, and more. Initial results from the AEGIS collaboration will be published as part of an upcoming ApJ Special Issue. For more info about AEGIS, visit the spiffy website here.
Using high-resolution spectra of K giant stars in nearby galaxies, we map the kinematics of local dwarf spheroidals and ellipticals and M31. With large aperture telescopes (e.g., Keck), we are able to measure the radial velocities out to large radii, extending far out into the stellar halos. Many results from this work have already been published (e.g., Geha et al. 2006, Kalirai et al. 2006, Guhathakurta et al. 2006), with more to come in the near future.
