Microsatellite and allozyme analyses reveal few genetic differences among spatially distinct aggregations of geoduck clams (Panopea abrupta, Conrad 1849)
(2004-12)
The genetic population structure of geoduck clams (Panopea abrupta) in inland waters of
Washington may affect fishery management and aquacultural practices involving this species. To
investigate genetic differentiation ...
Deep SAURON Spectral-Imaging of the diffuse Lyman-alpha halo LAB1 in SSA22
(2004-06)
We have used the SAURON panoramic integral field spectrograph to study the structure of the Ly-alpha emission-line halo, LAB1, surrounding the sub-millimeter galaxy SMM J221726+0013. This emission-line halo was discovered ...
A population of hot, dusty ultra-luminous galaxies at z~2
(2004-10-20)
We report spectroscopic redshifts for 18 microJy-radio galaxies at mean redshift of z=2.2 that are faint at both submmillimeter (submm) and optical wavelengths. While the radio fluxes of these galaxies could indicate ...
Obscured and unobscured active galactic nuclei in the Spitzer Space Telescope First Look Survey
(2004-09)
Selection of active galactic nuclei (AGN) in the infrared allows the discovery of AGN whose optical emission is extinguished by dust. In this paper, we use the Spitzer Space Telescope First Look Survey (FLS) to assess what ...
Evidence for extended, obscured starbursts in submm galaxies
(2004-08-20)
We compare high-resolution optical and radio imaging of 12 luminous submm galaxies at z=2.2+/-0.2 observed with HST and the MERLIN and VLA at comparable spatial resolution, 0.3" (2kpc). The radio emission traces the likely ...
Characterization of Extragalactic 24micron Sources in the Spitzer First Look Survey
(2004-09)
In this Letter, we present the initial characterization of extragalactic 24um sources in the Spitzer First Look Survey (FLS) by examining their counterparts at 8um and R-band. The color-color diagram of 24-to-8 vs. 24-to-0.7um ...
Clustering of Submillimeter-Selected Galaxies
(2004-08-20)
Using accurate positions from very deep radio observations to guide multi-object Keck spectroscopy, we have determined a substantially complete redshift distribution for very luminous, distant submillimeter(submm)-selected ...
Further multiwavelength observations of the SSA22 Ly_alpha emitting `blob'
(2004-05)
We present new follow-up observations of the sub-mm luminous Ly_alpha-emitting object in the SSA22 z=3.09 galaxy overdensity, referred to as `Blob 1' by Steidel et al.(2000). In particular we discuss high resolution Hubble ...
The Far- and Mid-Infrared/Radio Correlations in the Spitzer Extragalactic First Look Survey
(2004-09)
Using the SPITZER SPACE TELESCOPE and the VLA, we present the first DIRECT evidence that the well-known far-infrared/radio correlation is valid to cosmologically significant redshift. We also confirm, with improved statistics ...
