Far-Infrared Surveys of the Sky

Science, 1967
A series of far-infrared surveys of the sky is searching for thermal radiation from interstellar grains and for other localized sources of far-infrared radiation. A balloon-borne germanium bolometer, cooled by liquid helium, is used in association with a telescope and spectral filters.

The Universe of Digital Sky Surveys

open access: yesThirty Years of Astronomical Discovery With UKIRT, 2016
These are the proceedings of a meeting in honour of Massimo Capaccioli at the occasion of his 70th birthday. The conference aimed at summarizing the results from the main current and past digital sky survey projects and at discussing how these can be ...

Infrared Sky Surveys

Space Science Reviews, 2009
A retrospective is given on infrared sky surveys from Thomas Edison’s proposal in the late 1870s to IRAS, the first sensitive mid- to far-infrared all-sky survey, and the mid-1990s experiments that filled in the IRAS deficiencies. The emerging technology for space-based surveys is highlighted, as is the prominent role the US Defense Department ...

Digital Optical Sky Surveys

Publications of the Astronomical Society of the Pacific, 1995
Cameras containing arrays of charge-coupled devides--or which are otherwise capable of sustained high data rates--enable optical sky surveys that compete in efficiency with photographic surveys in terms of area of sky covered per unit observing time.

The ultraviolet sky: An overview from the GALEX surveys

open access: yesAdvances in Space Research, 2014
The Galaxy Evolution Explorer (GALEX) has performed the first surveys of the sky in the ultraviolet (UV). Its legacy is an unprecedented database with more than 200 million source measurements in far-UV (FUV) and near-UV (NUV), as well as wide-field ...

Sky surveys with ASCA — Deep Sky Survey

Astronomische Nachrichten, 1998
AbstractASCA Deep Sky Survey (DSS) is aimed to investigate the constituents of the CXB in 2–10 keV band, by faint source survey observations reaching to the source confusion limit of ASCA X‐Ray Telescopes. So far, 0.29 deg2 sky regions were systematically studied and about 40% of the CXB intensity was resolved into discrete sources.

Sky surveys with ASCA — Large Sky Survey

Astronomische Nachrichten, 1998
AbstractWe have carried out the first systematic wide‐area survey around a Galactic pole region with the ASCA satellite in the 0.7–10 keV energy band (Large Sky Survey; LSS). The observed area amounts to 7 deg2. To make the best use of ASCA capability, we have developed a new source‐detection method where the complicated detector responses are fully ...

New Approaches to Object Classification in Synoptic Sky Surveys [PDF]

open access: yes, 2008
Digital synoptic sky surveys pose several new object classification challenges. In surveys where real-time detection and classification of transient events is a science driver, there is a need for an effective elimination of instrument-related artifacts ...
