The Sloan Digital Sky Survey
The Sloan Digital Sky Survey is an ambitious, multi-institutional project to create a huge digital imaging and spectroscopic data bank of 25% of the celestial sphere, approximately 10,000 deg2 centred on the north galactic polar cap. The photometric atlas will be in 5 specially-chosen colours, covering the π ster of the Survey area to a limiting magnitude of r′∼23.1, on 0′′ . 4 pixels, resultin...
متن کاملThe Sloan Digital Sky Survey
The Sloan Digital Sky Survey (SDSS) will carry out a digital photometric and spectroscopic survey over π steradians in the northern Galactic cap. An array of CCD detectors used in drift-scan mode will image the sky in five passbands to a limiting magnitude of r′ ∼ 23. Selected from the imaging survey, 10 galaxies, 10 quasars and selected samples of stars will be observed spectroscopically. In a...
متن کاملDigital Sky - Panel
The objectjve of the panel is to provide a forum for domain experts in the area of Digital Sky to present some of their recent research work and point out some of the critical challenges that need to be addressed by Computer and Information Scientists focusing on the area of Digital Libraries. Each panelist will be allocated 20 minutes to present his/her recent related research work followed by...
متن کاملDigital Sky Survey
Current X-ray observatories, archival X-ray data, and the Sloan Digital Sky Survey (SDSS) represent a powerful combination for addressing key questions about active galactic nuclei (AGN). We describe a few selected issues at the forefront of X-ray AGN research and the relevance of the SDSS to them. Bulk X-ray/SDSS AGN investigations, X-ray weak AGN, red AGN, hard X-ray selected AGN, high-redshi...
متن کاملThe Digital Sky Project: Prototyping Virtual Observatory
Astronomy is entering a new era as multiple, large area, digital sky surveys are in production. The resulting datasets are truly remarkable in their own right; however, a revolutionary step arises in the aggregation of complimentary multi-wavelength surveys (i.e., the crossidentification of a billion sources) . The federation of these large datasets is already underway, and is producing a major...
