Kinematics of Distant Galaxies from Keck
David C. Koo
DEEP is a two-phase spectral survey of faint field galaxies with the Keck Telescopes. The goals include exploring galaxy formation and evolution, mapping distant large scale struct…
Keck Spectroscopy and Imaging of Faint Galaxies Identified as MicroJansky Radio Sources
Nathan Roche, James Lowenthal, David Koo
We investigate the nature of the faintest radio sources detected in 3 VLA surveys, to faint limits 8 microJy at 8.5 GHz. Using the Keck Low Resolution Imaging Spectrograph in BRI a…
A Deep Keck Spectral Survey of Cl0024+1654 at z=0.4
Anne J. Metevier, David C. Koo, Luc Simard +1
We have undertaken a Keck spectral survey of galaxies to R~24 near the central region of Cl0024+1654 at z=0.4. The spectral resolution and slits have been selected to yield kinemat…
A Pilot Study of the Tully-Fisher Relation in Cl0024+1654 at z=0.4
Anne J. Metevier, David C. Koo, Luc Simard
We present the first determination of the Tully-Fisher relation (TFR) for a distant galaxy cluster. We have measured internal kinematics of seven members of Cl0024+1654 from spatia…
Are There Blue, Massive E/S0s at z < 1 ?: Kinematics of Blue Spheroidal Galaxy Candidates
Myungshin Im, S. M. Faber, Karl Gebhardt +5
Several recent studies find that 10 - 50% of morphologically selected field early-type galaxies at redshifts z <= 1 have blue colors indicative of recent star formation. Such ``blu…
