The 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 کاملThe 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 کاملActive Galaxies in the Sloan Digital Sky Survey III: from quasars to radio galaxies?
In this third of a series of papers concerning active galaxies in the FIRST and Sloan Digital Sky Surveys, we analyze the spectroscopic and radio properties of a sample of narrow-line Active Galactic Nuclei (AGN), broad-line Seyfert I galaxies, and Quasars in the local universe in order to investigate the dependence of their activity on the mass, spin and accretion rates of the supermassive bla...
متن کاملTwo new AM Canum Venaticorum binaries from the Sloan Digital Sky Survey III
The AM Canum Venaticorum (AM CVn) binaries are a rare group of ultra-short period, masstransferring white dwarf binaries, some of which may be Type Ia supernova progenitors. More than a third of the total known population of AM CVn binaries have been discovered via the Sloan Digital Sky Survey (SDSS). Here, we discuss our search for new AM CVns in the SDSS spectroscopic data base, and present t...
