The 2dF QSO Redshift Survey - V. The 10k catalogue

Abstract

We present a catalogue comprising over 10000 QSOs covering an effective area of 289.6 sq. degrees, based on spectroscopic observations with the 2-degree Field instrument at the Anglo-Australian Telescope. This catalogue forms the first release of the 2-degree Field QSO Redshift Survey. QSO candidates with 18.25<b_J<20.85 were obtained from a single homogeneous colour-selected catalogue based on APM measurements of UK Schmidt photographic material. The final catalogue will contain approximately 25000 QSOs and will be released to the public at the end of 2002, one year after the observational phase is concluded.Comment: 9 pages including 8 figures to be published in the April 21 issue of MNRAS, vol. 322, L29. Access to the catalogue and spectra is available at http://www.2dfquasar.org

A catalogue of quasars and active nuclei: 13th edition

“…The number of known quasars has since steadily increased until the year 2000 (see Table 1). The release of both the 2dF catalogue (Croom et al 2001(Croom et al , 2004 and the first four data releases (Abazajian et al 2003(Abazajian et al , 2004(Abazajian et al , 2005Adelman-McCarthy et al 2006) of the "Sloan Digital Sky Survey" (Fan et al 1999) has dramatically increased the number of known quasars justifying the 10th, 11th, and 12th editions of the present catalogue. The recent publication of the last three data releases (5th, 6th, and 7th) (Adelman-McCarthy et al 2007; Abazajian et al 2009) of the SDSS, which has again almost doubled the number of known quasars, made a new edition timely.…”

Spectroscopy and Photometry of Stellar Objects from the Second Byurakan Survey

“…This survey is aimed at the selection of about 25,000 QSOs in two strips of the northern and southern sky with a total area of about 740 deg2. The data for more than 10,000 QSOs in the magnitude range in an area of about 290 deg2 18.25 \ b J \ 20.85 have recently been released (Croom et al 2001).…”

The QSO Luminosity Function from the 2dF QSO Redshift Survey and the Associated 6dF QSO Redshift Survey at 0.3 ≤ z ≤ 2.4

“…For the study of QSO luminosity function we use the data taken from the 2 Degree Field (2dF) QSO Redshift Survey (2QZ) [16] and 6 Degree Field (6dF) QSO Redshift Survey (6QZ). Spectroscopic observations for the 2QZ and 6QZ were made with the 2dF instrument at the Anglo-Australian Telescope (AAT) [17] [16,18,19,20,21].…”

“…Spectroscopic observations for the 2QZ and 6QZ were made with the 2dF instrument at the Anglo-Australian Telescope (AAT) [17] [16,18,19,20,21]. Each strip is contiguous except for small regions around bright stars.…”

“…The data from both the 2dF and 6dF were reduced using the pipeline data reduction system 2DFDR [24]. Identification of spectra and the determination of redshifts of the QSO candidates were carried out by an automated program known as AUTOZ [16]. For the 2QZ and 6QZ surveys completeness, and sources of incompleteness, the four types of completeness i.e.…”
