The Redshift Distribution of the TOUGH Survey [PDF]
EAS Publications Series, 2013 We present the redshift results from a Very Large Telescope program aimed at optimizing the legacy value of the Swift mission: to characterize a homogeneous, X-ray selected, sample of 69 GRB host galaxies. 19 new redshifts have been secured, resulting in

The Anglo-Australian Redshift Survey [PDF]
Symposium - International Astronomical Union, 1983 The aim of the survey is to sample a relatively large, randomly chosen volume of the Universe in order to study the large-scale distribution of galaxies using the two-point correlation function, the peculiar velocities between galaxy pairs and to provide an estimate of the galaxian luminosity function that is unaffected by density inhomogeneities and ...

Redshift Surveys With 2DF [PDF]
Highlights of Astronomy, 1998 This IAU Joint Discussion proposes to address the subject of redshift surveys in the 21st century. This paper, however, deals with two major new redshift surveys that those involved sincerely hope will be completed in the 20th century. Nonetheless, these surveys are relevant to the topic of the meeting, as they clearly foreshadow the scope and style of

The 2dF Galaxy Redshift Survey: spectra and redshifts [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250 000 galaxies. This paper describes the survey design, the spectroscopic observations, the redshift measurements and the survey data base. The 2dFGRS uses the 2dF multifibre spectrograph on the Anglo-Australian Telescope, which is capable of observing 400 ...

Cosmology with photometric redshift surveys [PDF]
Monthly Notices of the Royal Astronomical Society, 2005 We explore the utility of future photometric redshift imaging surveys for delineating the large-scale structure of the Universe, and assess the resulting constraints on the cosmological model. We perform two complementary types of analysis: (1) We quantify the statistical confidence and the accuracy with which such surveys will be able to detect and ...

The miniJPAS survey: Photometric redshift catalogue [PDF]
Astronomy & Astrophysics, 2021 MiniJPAS is a ∼1 deg2 imaging survey of the AEGIS field in 60 bands, performed to demonstrate the scientific potential of the upcoming Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS). Full coverage of the 3800–9100 Å range with 54 narrow-band filters, in combination with 6 optical broad-band filters, allows for extremely ...

A Redshift Survey of IRAS Galaxies [PDF]
Symposium - International Astronomical Union, 1988 We have completed a redshift survey of approximately 2200 IRAS galaxies, flux limited at 60μ. The survey covers 76% of the sky and has a characteristic depth of ≈ 6000 km s−1, making it ideal for large scale structure studies requiring whole sky coverage.

The 2Mass Redshift Survey [PDF]
Highlights of Astronomy, 1998 With the current convergence of determinations of the Hubble Constant (e.g. The Extragalactic Distance Scale, 1997, Livio, Donahue and Panagia, eds.) to values within ±25% rather than a factor of two, and the clear possibility of determining q0 using high redshift supernovae (Garnavich et al.

The FLAIR–DENIS Redshift Survey [PDF]
Publications of the Astronomical Society of Australia, 1997 AbstractThe DEep Near-Infrared Survey of the southern sky (DENIS) will produce an important by-product: a clean, complete view of the local Universe to z ∼ 0·07 for 105 galaxies. We identify the FLAIR multi-fibre system on the UKST as an extremely competitive facility to undertake follow-up spectroscopy for this sample due to the need to cover wide ...
