The Angular Clustering of Lyman-break Galaxies at Redshift
We have measured the angular correlation function w(θ) for a sample of 871 Lyman-break galaxies (LBGs) in five fields at redshift z ∼ 3. Fitting the power-law Awθ −β to a weighted average of w(θ) from the five fields over the range 12 < ∼ θ < ∼ 330 arcsec, we find Aw ∼ 2 arcsec and β ∼ 0.9. The slope is, within the errors, the same as for galaxy samples in the local and intermediate redshift un...
متن کاملThe Clustering Properties of Lyman–break Galaxies at Redshift
We present a new measure of the angular two–point correlation function of Lyman–break galaxies (LBGs) at z ∼ 3, obtained from the variance of galaxy counts in 2–dimensional cells. By avoiding binning of the angular separations, this method is significantly less affected by shot noise than traditional measures, and allows for a more accurate determination of the correlation function. We used a s...

متن کاملExpected Sub-mm Emission and Dust Properties of Lyman Break Galaxies at High Redshift
We investigate expected sub-mm emission and dust properties of the Lyman Break Galaxies (LBGs) in the Hubble Deep Field (HDF). The SCUBA Deep Survey (Hughes et al., 1998) provides an upper limit of the 850μm flux densities of the LBGs. With this constraint, we argue that a typical ultra-violet to far-infrared spectral shape of the high-redshift LBGs is rather close to a template spectrum of low...
متن کاملThe Structure and Clustering of Lyman Break Galaxies
The number density and clustering properties of Lyman-break galaxies (LBGs) are consistent with them being the central galaxies of the most massive dark halos present at z ∼ 3. This conclusion holds in all currently popular hierarchical models for structure formation, and is almost independent of the global cosmological parameters. We examine whether the sizes, luminosities, kinematics and star...
