As a prerequisite for cosmological studies using adaptive optics techniques, we have begun to identify and character- ize faint sources in the vicinity of bright stars at high Galactic latitudes. The initial phase of this work has been a program of Ks imaging conducted with SOFI at the ESO NTT. From observations of 42 southern fields evenly divided between the spring and autumn skies, we have identified 391 additional stars and 1589 galaxies lying at separations ∆θ ≤ 60 �� from candidate guide…

A catalogue of potential adaptive optics survey fields from the UKIRT archive
We present a multicolour catalogue of faint galaxies situated close to bright stars, V ≤ 15, with the aim of identifying high-redshift galaxies suitable for study with adaptive optics-equipped
Morphological evolution of z ~ 1 galaxies from deep K-band AO imaging in the COSMOS deep field
Context. We present the results of an imaging program of distant galaxies (z ∼ 0.8) at high spatial resolution (∼0.1 �� ) aiming at studying their morphological evolution. We observed 7 fields of 1 �
Galaxy morphology and evolution from SWAN adaptive optics imaging
We present the results from adaptive optics (AO) assisted imaging in the Ks band of an area of 15 arcmin 2 for SWAN (Survey of a Wide Area with NACO). We derive the high resolution near-IR morphology
SWAN: galaxy morphology and evolution from adaptive optics-assisted imaging
Morphology is among the most appropriate ways to characterize the properties of galaxies. Indeed, we will reach a complete understanding of galaxies only by deriving the mechanisms responsible for
We present a deep K'-band (2.12 μm) imaging of the 1' × 1' Subaru Super Deep Field (SSDF) taken with the Subaru adaptive optics (AO) system. Total integration time of 26.8 hr results in the limiting
Accounting for the anisoplanatic point spread function in deep wide-field adaptive optics images
In this paper we present the approach we have used to determine and account for the anisoplanatic point spread function (PSF) in deep adaptive optics (AO) images for the Survey of a Wide Area with


Faint Field Galaxies around Bright Stars: A New Strategy for Imaging at the Diffraction Limit
This paper presents a new strategy for observing faint galaxies with high‐order natural guide star systems. We have imaged five high Galactic latitude fields within the isoplanatic patch of bright
Galaxy number counts—IV. Surveying the Herschel Deep Field in the near-infrared
We present results from two new near-infrared imaging surveys. One survey covers 47.2 arcmin2 to K(3σ)=20 mag whilst a second, deeper catalogue covers a subarea of 1.8 arcmin2 to K(3σ)=22.75 mag.
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
Exploring the Structure of Distant Galaxies with Adaptive Optics on the Keck II Telescope
We report on the first observation of cosmologically distant field galaxies with a high-order adaptive optics (AO) system on an 8-10 m class telescope. Two galaxies were observed at 1.6 μm at an

Deep near-infraredimages of a blank 2 � ×2 � section of skynear the galactic north pole taken by Subaru Telescope are presented. The total integration times of the J and Kbands were 12.1 hr and 9.7
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
Observations of faint galaxies with adaptive optics
Encouraged by imaging of faint galaxies around bright stars using ALFA on the 3.5-m telescope at Calar Alto, we have begun a survey to identify a large number of candidate sources near bright stars.
Near-Infrared Galaxy Counts to J and K ~ 24 as a Function of Image Size*
