Imaging and photometric observations of a statistically complete sample of galaxies in 12 high-latitude fields, obtained in the BJ (360-520 nm), R (580-720 nm) and I (780-1100 nm) bands using CCD detectors on the 4-m telescopes at CTIO and KPNO, are reported. The data are presented in extensive graphs and sample images and analyzed in detail with reference to theoretical models of galactic origin and evolution. The galaxy number-count slopes, d(log N)/dm, are found to be sub-Euclidean, varying… 

Colors and K-Band Counts of Extremely Faint Field Galaxies

We combine deep K-band (W. M. Keck Telescope) with V- and I-band (New Technology Telescope) observations of two “blank” high Galactic latitude fields, surveying a total of ~2 arcmin2. The K-band

The Hawaii K-Band Galaxy Survey. II. Bright K-Band Imaging

We present the results of a wide-field K-selected galaxy survey with complementary optical I- and B-band imaging in six fields with a total coverage of 9.8 deg2. The observations were carried out on

The FORS Deep Field: Field selection, photometric observations and photometric catalog ,

The FORS Deep Field project is a multi-colour, multi-object spectroscopic investigation of a ∼7 � × 7 � region near the south galactic pole based mostly on observations carried out with the FORS

The Nature of Compact Galaxies in the Hubble Deep Field. I. Global Properties

We present 10 m Keck spectroscopy and photometry for a sample of 61 small (r1/2 ≤ 0.″5), faint (I814 ≤ 23.74), high-surface brightness (μI814 < 22.2 mag arcsec-2) galaxies in fields flanking the

Deep U-B-V imaging of the Lockman Hole with the LBT Observations and number counts

We used the large binocular camera (LBC) mounted on the large binocular telescope (LBT) to observe the Lockman Hole in the U, B, and V bands. Our observations cover an area of 925 arcmin 2 . We

Deep optical imaging of the field of PC 1643+4631A&B – I. Spatial distributions and the counts of faint galaxies

We present deep optical images of the PC 1643+4631 field, obtained at the William Herschel Telescope (WHT). This field contains two quasars at redshifts z=3.79 and 3.83 and a cosmic microwave

Faint field galaxies: an explanation of the faint blue excessusing number evolution models

Pure luminosity evolution models for galaxies provide an unacceptable fit to the redshifts and colors of faint galaxies. In this paper we demonstrate, using HST morphological number counts derived

Galaxy Number Counts from the Sloan Digital Sky Survey Commissioning Data

We present bright galaxy number counts in five broad bands (u′, g′, r′, i′, z′) from imaging data taken during the commissioning phase of the Sloan Digital Sky Survey (SDSS). The counts are derived

Lensing the background population of galaxies

Deep CCD surveys to 29 mag from .32 to .9 micron wavelength reveal an isotropic population of very blue galaxies. There are over 200,000 of these objects per square degree per mag. The redshift of

Evidence for Galaxy Interactions/Mergers from Medium Deep Survey WFPC2 Data

We examine the morphological and statistical properties of close galaxy pairs from two sets of 28 WFPC2 fields, acquired for the Medium Deep Survey (MDS) and the Groth-Westphal Survey (GWS) in F606W
