Deep R-band photometry of the Chandra Deep Field South from the COMBO-17 survey

چکیده
We report on deep multi-color imaging (R5σ = 26.0) of the Chandra Deep Field South, obtained with the Wide Field Imager (WFI) at the MPG/ESO 2.2 m telescope on La Silla as part of the COMBO-17 survey. We include an overview of the COMBO-17 project and a detailed reduction scheme for WFI survey data. We discuss particular treatment necessary for accurate flatfielding of WFI images taken in the second half of 1999. As a result we present a catalog of 63501 objects in a field measuring 31.′5×30′ with astrometry and photometry. A sample of 35 variable objects is selected from two-epoch photometry. We try to give interpretations based on color, morphology and variation amplitude.

متن کاملH-band observations of the Chandra Deep Field South
We report preliminary results of our H-band survey of the Chandra Deep Field South (CDFS). The observations were made using SofI on the NTT, and cover 0.027 square degrees with a 50% completeness limit ofH =20.5, and 0.17 square degrees with a 50% completeness limit of H =19.8. We used SExtractor to extract sources from our fields. In total we have detected 4819 objects. Star-galaxy separation ...
متن کاملVariability - selected active galactic nuclei from supernova search in the Chandra deep field south
Context. Variability is a property shared by virtually all active galactic nuclei (AGNs), and was adopted as a criterion for their selection using data from multi epoch surveys. Low Luminosity AGNs (LLAGNs) are contaminated by the light of their host galaxies, and cannot therefore be detected by the usual colour techniques. For this reason, their evolution in cosmic time is poorly known. Consis...
متن کاملThe Chandra Deep Field-south Survey: 2 Ms Source Catalogs
We present point-source catalogs for the ≈ 2 Ms exposure of the Chandra Deep Field-South (CDF-S); this is one of the two most-sensitive X-ray surveys ever performed. The survey covers an area of ≈ 436 arcmin2 and reaches on-axis sensitivity limits of ≈ 1.9× 10−17 and ≈ 1.3× 10−16 ergs cm−2 s−1 for the 0.5–2.0 and 2–8 keV bands, respectively. Four hundred and sixty-two X-ray point sources are de...
متن کاملCOMBO - 17 measurements of the effect of environment on the type - dependent galaxy luminosity function
We have developed a method to calculate overdensities in multicolour surveys, facilitating a direct comparison of the local density contrast measured using galaxy samples that have different redshift error distributions, i.e. for red and blue, or bright and faint galaxies, respectively. We calculate overdensities in small redshift slices (∆z = 0.02, which at z = 0.3 corresponds roughly to ∆rcom...
