The 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 INT - WFS + 2 dFGRS : The Local Space & Luminosity Density
We discuss the quantification of the local galaxy population and the impact of the " New Era of Wide-Field Astronomy " on this field, and, in particular, systematic errors in the measurement of the Luminosity Function. New results from the 2dFGRS are shown in which some of these selection effects have been removed. We introduce an INT-WFS project which will further reduce the selection biases. ...
متن کاملThe structure of elliptical galaxies in the Virgo cluster . Results from the INT Wide Field Survey
We report on a complete CCD imaging survey of 226 elliptical galaxies in the North-East quadrant of the Virgo cluster, representative of the properties of giant and dwarf elliptical galaxies in this cluster. We fit their radial light profiles with the Sersic r model of light distribution. We confirm the result of Graham & Guzman (2003) that the apparent dichotomy between E and dE galaxies in th...
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 ...
متن کاملWide-field VLBI Imaging
We discuss the technique of Wide-field imaging as it applies to Very Long Baseline Interferometry (VLBI). In the past VLBI data sets were usually averaged so severely that the field-of-view was typically restricted to regions extending a few hundred milliarcseconds from the phase centre of the field. Recent advances in data analysis techniques, together with increasing data storage capabilities...
