The Sloan Digital Sky Survey quasar lens search. IV. Statistical lens sample from the fifth data release
(2010)
We present the second report of our systematic search for strongly lensed quasars from the data of the Sloan Digital Sky Survey (SDSS). From extensive follow-up observations of 136 candidate objects, we find 36 lenses in ...
The Sloan Digital Sky Survey Quasar Lens Search. III. Constraints on Dark Energy from the Third Data Release Quasar Lens Catalog
(2008)
We present cosmological results from the statistics of lensed quasars in the Sloan Digital Sky Survey (SDSS) Quasar Lens Search. By taking proper account of the selection function, we compute the expected number of quasars ...
The Sloan Digital Sky Survey Quasar Lens Search. II. Statistical Lens Sample from the Third Data Release
(2008)
We report the first results of our systematic search for strongly lensed quasars using the spectroscopically confirmed quasars in the Sloan Digital Sky Survey (SDSS). Among 46,420 quasars from the SDSS Data Release 3 (~4188 ...
A large-scale radio polarization survey of the southern sky at 21 cm
(Copernicus Publications, 2004-12)
We have successfully reduced the polarization data from the recently published 21 cm continuum survey of the southern sky carried out with a 30-m antenna at Villa Elisa (Argentina). We describe the reduction and calibration ...
A high sensitivity HI survey of the sky at delta <= -25 deg
(EDP Sciences, 2000-02)
This paper reports on a high sensitivity lambda 21-cm neutral hydrogen survey of the sky south of delta <= -25o. A total of 50980 positions lying on a galactic coordinate grid with points spaced by (bigtriangleup l, ...
A high sensitivity HI survey of the sky at delta <= -25: final data release
(EDP Sciences, 2005-09)
We present the final data release of the high sensitivity λ 21-cm neutral hydrogen survey of the sky south of δ ≤ -25 °. A total of 50 980 positions lying on a galactic coordinate grid with points spaced by (Δ l, Δ b) = ...
