- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- This DSA hosts data release 1 of the ATLAS Survey housed at the Wide Field Astronomy Unit at the Univeristy of Edinburgh. The initial aim of ATLAS is to survey 4500 deg2 of the Southern Sky at high galactic latitudes to comparable depths to the SDSS in the North. The VST ATLAS will be the first step towards a panoramic digital survey of the Southern Sky in the optical bands. The ATLAS will complement the proposed VISTA Hemisphere Survey in the South.

- Title:
- Chandra X-ray Observatory Data Archive
- Short Name:

- Date:

- Publisher:
- Chandra X-ray Observatory
- Description:
- The Chandra X-ray Observatory is the U.S. follow-on to the Einstein Observatory. Chandra was formerly known as AXAF, the Advanced X-ray Astrophysics Facility, but renamed by NASA in December, 1998. Originally three instruments and a high-resolution mirror carried in one spacecraft, the project was reworked in 1992 and 1993. The Chandra spacecraft carries a high resolution mirror, two imaging detectors, and two sets of transmission gratings. Important Chandra features are: an order of magnitude improvement in spatial resolution, good sensitivity from 0.1 to 10 keV, and the capability for high spectral resolution observations over most of this range.

- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- Catalog of astrometry and photometry of detected point sources in the Far red optical (0.82-micron I-band) and near-infrared (1.25-micron J- and 2.15-micron Ks bands). ~16,700 square degrees of the southern sky

- Title:
- 6dF Galaxy Survey Data Release 2
- Short Name:
- 6dF DR2
- Date:
- 23 Jan 2024 09:39:52
- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- The 6dF Galaxy Survey (6dFGS) aims to measure the redshifts of around 150 000 galaxies, and the peculiar velocities of a 15 000-member subsample, over almost the entire southern sky. The table called Spectra contains the redshifts and qualities of all the observations. When complete, it will be the largest redshift survey of the nearby Universe, reaching out to about z ~ 0.15, and more than an order of magnitude larger than any peculiar velocity survey to date. The targets are all galaxies brighter than K tot = 12.75 in the 2MASS Extended Source Catalog (XSC), supplemented by 2MASS and SuperCOSMOS galaxies that complete the sample to limits of (H, J , r F, bJ) = (13.05, 13.75, 15.6, 16.75).

- FIRST Survey Catalogue (03Apr11 Version)
- Short Name:

- Date:

- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- 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. The catalogue covers a total of about 9033 square degrees of sky (8422 square degrees in the north Galactic cap and 611 square degrees in the south Galactic cap.)

- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- The Galaxy Evolution Explorer (GALEX) satellite is a NASA mission led by the California Institute of Technology to investigate how star formation in galaxies evolved from the early Universe up to the present. GALEX uses microchannel plate detectors to obtain direct images in the near-UV (NUV) and far-UV (FUV) and a grism to disperse light for low resolution spectroscopy

- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- The Infrared Astronomical Satellite Archive is an implementation of the IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986). This is a catalogue of some 250,000 well-confirmed infrared point sources observed by the Infrared Astronomical Satellite, i.e., sources with angular extents less than approximately 0.5, 0.5, 1.0, and 2.0 arcmin in the in-scan direction at 12, 25, 60, and 100 microns, respectively.

- 2MASS Photometric Redshift catalogue (2MPZ)
- Date:

- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- The 2MASS Photometric Redshift catalogue (2MPZ) is constructed by cross-matching 2MASS XSC, WISE and SuperCOSMOS all-sky samples and employing the artificial neural network approach (the ANNz algorithm, Collister & Lahav 2004), trained on several redshift surveys (2MRS, SDSS, 6dFGS, 2dFGRS and ZCAT). The derived photometric redshifts have errors nearly independent of distance, with an all-sky accuracy of Ïz = 0.015, and a very small percentage of outliers. These redshift estimates have a typical precision of 12% for all the 2MASS XSC galaxies that lack spectroscopy. The resulting 2MPZ sample contains almost 1 million galaxies with a median redshift of z=0.07. This catalogue is described in Bilicki et al. 2014, ApJS, 210, 9.

- Publisher:
- WFAU, Institute for Astronomy, University of Edinburgh
- Description:
- The Millennium Galaxy Catalogue (MGC) is a 37.5 deg2, medium-deep, B-band imaging survey obtained with the Wide Field Camera on the INT. The survey region is a long, 35 arcmin wide strip along the equator, covering from 10h 00m to 14h 45m and is fully contained within the regions of both the Two Degree Field Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS).
