20 Jun 2000 | | Journal: | Astron.J. 120 (2000) 2082 | | Subject: | astro-ph | | Affiliation: | IAS), Judith G. Cohen, Roger Blandford (Caltech | | Abstract: | A clustering analysis is performed on two samples of $sim 600$ 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 $z_{med}approx 0.55$. Strong clustering is obvious, with every pencil-beam field containing a handful of narrow redshift-space features, corresponding to galaxy structures with sizes of 5 to 20 Mpc. The structures are not obviously organized on planes, though one prominent, colinear triplet of structures is observed, spanning $sim 20$ Mpc. This may be evidence of a filament. A galaxy--galaxy correlation function calculation is performed. No significant evolution of clustering (relative to stable clustering) is found in the redshift range 0.3 | | Source: | arXiv, astro-ph/0006284 | | Services: | Forum | Review | PDF | Favorites | |
