The Great Observatories Origins Deep Survey(GOODS)
GOODS North and South Open SkyNode. GOODS aims to unite extremely deep observations from NASA's Great Observatories, the Spitzer Space Telescope, Hubble, and Chandra, ESA's XMM-Newton, and from the most powerful ground-based facilities, to survey the distant universe to the faintest flux limits across the broadest range of wavelengths. GOODS incorporates a Spitzer Space Telescope Legacy Program to carry out the deepest observations with that facility at 3.6 to 24 microns, an HST Treasury Program for deep high-resolution optical imaging. GOODS will survey a total of roughly 320 square arcminutes in two fields centered on the Hubble Deep Field North and the Chandra Deep Field South. The space-based observations will be complemented by ground-based imaging and spectroscopy, including an extensive commitment of ESO and NOAO observing time.

The Hubble Deep Field South(HDFS)
A second Hubble Deep Field campaign was carried out between late September and October of 1998. The raw, pipeline calibrated and reprocessed data were released to the community on November 23, 1998. The rationale for undertaking a second deep field campaign followed from the wealth of information that has come out of HDF-N, and from the desire to provide a point of focus for similar studies of the distant universe from southern-hemisphere facilities. The wide public access to the HDF-N data stimulated extensive followup observations across the electromagnetic spectrum, both from major ground-based observatories and from other satellites.

The Hubble Ultra Deep Field(UDF)
The ACS Ultra Deep Field (UDF) is a survey carried out using the Advanced Camera for Surveys (ACS) on HST and taking advantage of the Director's Discretionary time. The UDF will consist of a single ultra-deep field (412 orbits in total) within the CDF-S GOODS area. Scientific drivers of the UDF include probing the tail of the reionization epoch, constraining the star formation history of the Universe, probing the faint end of the galaxy luminosity function, and tracking the origin, structure, and merger history of galaxies as they evolve onto and off the Hubble sequence.

The Hubble Deep Field North(HDFN)
Hubble Deep Field North Open SkyNode. The Hubble Deep Field (HDF) is a Director's Discretionary program on HST in Cycle 5 to image a typical field at high galactic latitude in four wavelength passbands as deeply as reasonably possible. In order to optimize observing in the time available, a field in the northern continuous viewing zone (CVZ) was selected and images were taken for 10 consecutive days, or approximately 150 orbits. Shorter 1-orbit images were also obtained of the fields immediately adjacent to the primary HDF in order to facilitate spectroscopic follow-up by ground-based telescopes. The observations were carried out from 18-30 December 1995, and the data are available to the community for study.

Faint Images of the Radio Sky at Twenty-centimeter(FIRST)
FIRST -- Faint Images of the Radio Sky at Twenty-cm -- is a project designed to produce the radio equivalent of the Palomar Observatory Sky Survey over 10,000 square degrees of the North and South Galactic Caps. Using the NRAO Very Large Array (VLA) and an automated mapping pipeline, we produce images with 1.8" pixels, a typical rms of 0.15 mJy, and a resolution of 5". At the 1 mJy source detection threshold, there are ~90 sources per square degree, ~35% of which have resolved structure on scales from 2-30"

THIRD REFERENCE CATALOGUE OF BRIGHT GALAXIES(RC3)
The Third Reference Catalogue of Bright Galaxies (RC3) attempts to be reasonably complete for galaxies having apparent diameters larger than 1' at the D25 isophotal level and total B-band magnitudes BT brighter than about 15.5, with a redshift not in excess of 15,000 km/s, as well as many other objects of interest, such as compact galaxies smaller than 1' or fainter than magnitude 15.5, and those already in RC2 (de Vaucouleurs et al. 1976).

Rosat(Rosat)
ROSAT, the ROentgen SATellite, was an X-ray observatory developed through a cooperative program between the Germany, the United States, and the United Kingdom. The satellite was designed and operated by Germany, and was launched by the United States on June 1, 1990. It was turned off on February 12, 1999. Power was supplied through 3 solar panels providing 1 kW of power during Sun-lit parts of the orbit, and through a rechargeable battery during the shadow phase (spacecraft night, up to 40 minutes per orbit).

2dF Galaxy Redshift Survey(TwoDf)
The Two Degree Field system (`2dF') is the AAT's (and arguably the world's) most complex astronomical instrument. It is designed to allow the acquisition of up to 400 simultaneous spectra of objects anywhere within a two degree field on the sky. It consists of a wide field corrector, an atmospheric dispersion compensator, a robot gantry which positions optical fibres to 0.3'' and two spectrographs each of which accepts 200 of the fibres to produce low to medium resolution spectra. A tumbling mechanism with two field plates allows the next field to be configured while the current field is being observed

2dF QSO Redshift Survey (2QZ)(Twoqz)
Using the AAT Two-Degree Field (2dF) to obtain redshifts for > 25000 B < 21 QSOs in two 75° × 5° declination strips in the South Galactic Pole and in an equatorial region at the North Galactic cap. The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure .

Infrared Astronomical Satellite(IRAS)
Infrared Astronomical Satellite OpenSkyNode The Infrared Astronomical Satellite (IRAS) was a joint project of the US, UK and the Netherlands. The IRAS mission performed an unbiased, sensitive all sky survey at 12, 25, 60 and 100 µm. IRAS increased the number of cataloged astronomical sources by about 70%, detecting about 350,000 infrared sources. IRAS discoveries included a disk of dust grains around the star Vega, six new comets, and very strong infrared emission from interacting galaxies as well as wisps of warm dust called infrared cirrus which could be found in almost every direction of space. IRAS also revealed for the first time the core of our galaxy, the Milky Way

NRAO/VLA Sky Survey(NVSS)
The NRAO VLA Sky Survey (NVSS) is a 1.4 GHz continuum survey covering the entire sky north of -40 deg declination. A detailed description appears in the 1998 May issue of The Astronomical Journal (Condon, J. J., Cotton, W. D., Greisen, E. W., Yin, Q. F., Perley, R. A., Taylor, G. B., & Broderick, J. J. 1998, AJ, 115, 1693). The principal NVSS data products are: A set of 2326 continuum image ``cubes,'' each covering 4 deg X 4 deg with three planes containing the Stokes I, Q, and U images. These images were made with a relatively large restoring beam (45 arcsec FWHM) to yield the high surface-brightness sensitivity needed for completeness and photometric accuracy. Their rms brightness fluctuations are about 0.45 mJy/beam = 0.14 K (Stokes I) and 0.29 mJy/beam = 0.09 K (Stokes Q and U). The rms uncertainties in right ascension and declination vary from < 1 arcsec for relatively strong (S > 15 mJy) point sources to 7 arcsec for the faintest (S = 2.3 mJy) detectable sources.

NOAO Deep Wide-Field Survey(NDWFS)
Cataloged parameters (including photometry and position) for objects detected in the images of the third data release (DR3) of the NOAO Deep Wide-Field Survey (NDWFS). The DR3 includes all the optical (Bw, R, and I pass-bands) imaging of our 9.3 square degree Boötes field as well as partial coverage of the field in the K-band. These catalogs were generated with SExtractor 2.3.2 (Bertin & Arnouts 1996, A&A 117, 393). Catalogs were generated in single-band mode for each sub-field and band. Information about the survey as well as the images from which the catalogs were generated can be found at: http://www.noao.edu/noao/noaodeep/, or http://archive.noao.edu/ndwfs/ Catalog and image copyright Association of Universities for Research in Astronomy Inc.

Sloan Digital Sky Survey (DR3)(SDSSDR3)
Simply put, the Sloan Digital Sky Survey is the most ambitious astronomical survey ever undertaken. The survey will map one-quarter of the entire sky in detail, determining the positions and absolute brightnesses of hundreds of millions of celestial objects. It will also measure the distances to more than a million galaxies and quasars. The SDSS addresses fascinating, fundamental questions about the universe. With the survey, astronomers will be able to see the large-scale patterns of galaxies: sheets and voids through the whole universe. Scientists have many ideas about how the universe evolved, and different patterns of large-scale structure point to different theories. The Sloan Digital Sky Survey will tell us which theories are right - or whether we will have to come up with entirely new ideas.

Quasars and Active Galactic Nuclei (11th Ed.) (QSO)
This catalogue is an update of the previous versions. The recent release of the final release of the 2dF quasar catalogue and of the first part of the SLOAN catalogue, almost doubling the number of known QSOs, led us to prepare an updated version of our Catalogue of quasars and active nuclei, which now contains 48921 quasars, 876 BL Lac objects and 15069 active galaxies (including 11777 Seyfert 1). Like the tenth edition, it includes position and redshift as well as photometry (U, B, V) and 6 and 11 cm flux densities when available. The present edition this catalogue contains the quasars with measured redshift known prior to August 1st, 2003.
