- Salamanca ( Singapore : World Scienti c ) THE DENIS 2 MICRON SURVEY AND ITS COSMOLOGICAL APPLICATIONSGary
نویسنده
چکیده
Near-infrared surveys have very promising cosmological applications. The DENIS 2 micron survey, currently in camera-testing, is scheduled to begin in early 1995, and to map the entire southern sky in the I, J , and K 0 bands. The steps for the near-homogeneous extraction of 10 5 galaxies are outlined, some pitfalls are given, and the estimated limiting capabilities of the survey are presented. A preliminary J-band image illustrates these capabilities and some of the hidden pitfalls. The necessary spectroscopic followup is shown to be feasible on a reasonably short timescale.
