Redshift Distribution of the Faint Submillimeter Galaxy Population
We present a Keck II LRIS spectroscopic follow-up study of the possible optical counterparts to a flux-limited sample of galaxies selected from an 850-μm survey of massive lensing clusters using the SCUBA bolometer array on the JCMT. These sources represent a population of luminous dusty galaxies responsible for the bulk of the 850-μm background detected by COBE and thus for a substantial fract...
متن کاملEstimating the Redshift Distribution of Faint Galaxy Samples
We present an empirical method for estimating the underlying redshift distribution N(z) of galaxy photometric samples from photometric observables. The method does not rely on photometric redshift (photo-z) estimates for individual galaxies, which typically suffer from biases. Instead, it assigns weights to galaxies in a spectroscopic subsample such that the weighted distributions of photometri...
متن کاملA Redshift Survey of the Submillimeter Galaxy Population
We have obtained spectroscopic redshifts using the Keck-I telescope for a sample of 73 submillimeter (submm) galaxies, with a median 850μm flux density of 5.7mJy, for which precise positions are available through their faint radio emission. The galaxies lie at redshifts out to z = 3.6, with a median redshift of 2.2 and an interquartile range z = 1.7–2.8. Modeling a purely submm flux-limited sam...
متن کاملFaint Galaxy Redshift Survey XII : Clustering of Galaxies
A clustering analysis is performed on two samples of ∼ 600 faint galaxies each, in two widely separated regions of the sky, including the Hubble Deep Field. One of the survey regions is configured so that some galaxy pairs span angular separations of up to 1 deg. The median redshift is zmed ≈ 0.55. Strong clustering is obvious, with every pencil-beam field containing a handful of narrow redshif...
متن کاملFaint Galaxy Redshift Survey XIV : Galaxy Morphology in the HDF ( North ) and its Flanking Fields
Morphological classifications are reported for Hubble Space Telescope (HST) images of 241 galaxies in the Hubble Deep Field (HDF) and its Flanking Fields (FF) with measured redshifts in the interval 0.25 < z < 1.2, drawn from a magnitude-limited redshift survey to R = 24.0. The galaxies are divided into three groups with redshifts in the intervals [0.25,0.6], [0.6,0.8], [0.8,1.2]. R606 images f...
