Abstract (from CDS):

When applied to deep photometric catalogs, the two-point angular correlation function, ω(θ), is a sensitive probe of the evolution of galaxy clustering properties. Here we present measurements of ω(θ) as a function of IABmagnitude and (R-I) color to a depth of IAB=24 on scales θ=7''-3', using a sample of ∼350,000 galaxies covering 5 deg2 in total over five separate fields. Using redshifts of 2954 galaxies in early DEEP2 Galaxy Redshift Survey data, we construct robust galaxy redshift distributions as a function of IABmagnitude and (R-I) color for galaxies in the range 0<z<2. We constrain models of the redshift evolution of galaxy clustering and find that significant growth of clustering has occurred from z≥1 to z=0. A model in which the comoving scale length, x0, evolves linearly with redshift, x0(z)=x0(0)(1-Bz), fits the data better than the ε model proposed by Groth & Peebles. The clustering properties depend strongly on observed (R-I) color, with both the reddest and bluest galaxies exhibiting large clustering amplitudes and steeper slopes. Different observed (R-I) color ranges are sensitive to very disparate redshift regimes. Red galaxies with (R-I)∼1.5 lie in a narrow redshift range centered at z∼0.85 and have a comoving scale length of clustering at z=0.85 of x0=5.0±0.3/h–1 Mpc. These galaxies have early-type spectra and are likely progenitors of massive local ellipticals. The bluest galaxies with (R-I)∼0 appear to be a mix of star-forming galaxies, both relatively local (z∼0.3-0.6) dwarfs and bright z>1.4 galaxies, as well as broad-line active galactic nuclei. We find that local blue dwarfs are relatively unclustered, with x0=1.6±0.2 h–1 Mpc. The z>1.4 blue galaxies have a larger clustering scale length, x0≳5 h–1 Mpc.

sedIcon
within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).
