Mining Sky Surveys for Astrophysically Interesting Variable Stars: The Cepheid Period Range
, 2009 We have undertaken a project to discover new type II Cepheids in two large-area sky surveys. However, most of the candidates from the surveys differ from type II Cepheids in their amplitude and period distributions and they form a separate, cooler ...

The infrared sky - A survey of surveys
Publications of the Astronomical Society of the Pacific, 1988A subjective review is given of the major milestones in infrared astronomy. Emphasis is placed on the survey efforts between 2 and 120 μm, the realm of the extrinsic photodetector. The historical developments in infrared astronomy and the pioneering, often marginally successful, survey attempts are put in the perspective of improving technology.

Symposium - International Astronomical Union, 1998
Photographic surveys have played a vital role in virtually every area of astronomical research over the last 50 years. Indeed, one can make a strong case that Schmidt telescopes in general, and the Palomar 48-inch Schmidt in particular, have made the most substantial contribution to our understanding of the Universe—at least at optical wavelengths. The

Large-Scale Simulations of Sky Surveys
Computing in Science & Engineering, 2014Large-volume sky surveys have accessed the Universe's vast temporal and spatial expanse via a remarkable set of measurements, and many more are sure to follow. To make new predictions for these cosmological observations and to properly interpret them, large-scale numerical simulation and modeling has become an essential tool.

The Infrared Astronomical Satellite Survey of the Sky
Symposium - International Astronomical Union, 1988The Infrared Astronomical Satellite (IRAS) surveyed 98% of the sky during 1983 at the wavelengths of 12, 25, 60, and 100 μm. The survey was enormously successful, producing catalogs containing more than 300,000 sources as well as digital images of the entire covered sky. The IRAS survey has revolutionized several fields of astronomy and impacted nearly

The Sloan Digital Sky Survey and beyond
ACM SIGMOD Record, 2008Our collaboration with Jim Gray has created some of the world's largest astronomy databases, and has enabled us to test many avant-garde ideas in practice. The astronomers have been very receptive to these and embraced Jim as a 'card carrying member' of their community.

The Ohio Sky Survey and other radio surveys
Vistas in Astronomy, 1977Abstract Section I indicates the importance of astronomical surveys and comments on some of the earliest radio surveys. Section II describes the Ohio Sky Survey which totals over 19,000 radio sources at 1415 MHz. Methods of observation, data reduction and analyses of reliability and completeness are considered.

SEZIONE SKY SURVEY Responsabile: Giorgio Bianciardi, Via del Colle, 1/5 - 53100 Siena La prima circolare del 1978 è stata spedita agli inizi di marzo; in questa appare il lavoro a cui i soci sono invitati a partecipare. Esso consiste essenzialmente nella continuazione del programma iniziato il precedente anno, dall’inizio di dicembre.
