Wide-Field Survey Reveals the Variable Sky
Figure 1. A comparison in area and depth between current major surveys and the FSVS. Adapted from the National Optical Astronomy Observatory (NOAO) Deep Wide-Field Survey Web pages (see www. noao.edu/noao/noaodeep/): SDSS, Sloan Digital Sky Survey (York et al. 2000); EIS (deep), ESO Imaging Survey (Deep) (Nonino et al. 1999); Deeprange, (Postman et al. 1998); INT-WAS, INT Wide Angle Survey (McM...
متن کاملThe INT Wide Field Imaging Survey ( WFS )
The 2.5m Isaac Newton Telescope(INT) is currently being used to carry out a major multi-colour, multi-epoch, CCD based wide field survey over an area of ∼100deg 2. The survey parameters have been chosen to maximise scientific return over a wide range of scientific areas and to complement other surveys being carried out elsewhere. Unique aspects of the survey is that it concentrates on regions o...
متن کاملThe XMM-Newton wide-field survey in the COSMOS field
Context. The COSMOS survey is a multiwavelength survey aimed to study the evolution of galaxies, AGN and large scale structures. Within this survey XMM-COSMOS a powerful tool to detect AGN and galaxy clusters. The XMM-COSMOS is a deep X-ray survey over the full 2 deg2 of the COSMOS area. It consists of 55 XMM-Newton pointings for a total exposure of ∼1.5 Ms with an average vignetting-corrected ...
متن کاملA Deep, Wide-Field Weak Lensing Survey with MEGACAM
This brief document is a response to the call for ideas for CFHT imaging surveys with MEGACAM. We have been carrying out wide eld, deep imaging at the CFHT for several years now, with the primary science goal of using weak lensing of faint galaxies to probe the dark matter distribution on a range of scales from galaxy halos through galaxy cluster scales to supercluster scales. Thus far we have ...
متن کاملWINGS : a Wide – field Imaging Nearby Galaxy clusters Survey
We present a two-band, wide-field imaging survey of an X– ray selected sample of 78 clusters in the redshift range z=0.03–0.07. The aim of the project is to provide the astronomical community with a complete set of homogeneous, CCD–based, surface photometry and morphological data of the nearby cluster galaxies located within 1.5Mpc from the cluster center. In all statistical studies concerning ...
