The Wide-Field DENIS Near-IR Imaging Survey and 6dF Redshift and Peculiar Velocity Surveys
The DENIS survey is currently imaging the entire southern sky in the I , J , and K wavebands. The current star/galaxy separation algorithm is presented and the galaxy counts are nearly perfectly Euclidean. 95% complete and reliable galaxy samples with better than 0.2 magnitude photometry should include 50 000 (K < 12.0), 500 000 (J < 14.8), and 900 000 (I < 16.5) galaxies, respectively, over th...
متن کاملThe 6dF Galaxy Survey
The 6dF Galaxy Survey (6dFGS) 1 is a spectroscopic survey of the entire southern sky with |b| > 10◦, based on the 2MASS near infrared galaxy catalog. It is conducted with the 6dF multi-fiber spectrograph attached to the 1.2-m UK Schmidt Telescope. The survey will produce redshifts for some 170,000 galaxies, and peculiar velocities for about 15,000 and is expected to be complete by June 2005.
متن کاملThe Tiling Algorithm for the 6dF Galaxy Survey
The Six Degree Field Galaxy Survey (6dFGS) is a spectroscopic survey of the southern sky, which aims to provide positions and velocities of galaxies in the nearby Universe. When completed the survey will produce approximately 170000 redshifts and 15000 peculiar velocities. The survey is being carried out on the Anglo Australian Observatory’s (AAO) UK Schmidt telescope, using the 6dF robotic fib...
متن کاملKlun+ Peculiar Velocity Survey
The enhanced Kinematics of the Local Universe (KLUN+) galaxy sample is a collection of galaxies suitable for Tully-Fisher (TF) or Faber-Jackson (FJ) distance estimation. Here we extract a subsample of 6229 KLUN+ galaxies closer than 80h −1 Mpc, and calculate their distances and peculiar velocities with the Iterative Normalized Distance method. Within this method we can derive an analytical form...
متن کاملSecond Data Release of the 6dF Galaxy Survey
The 6dF Galaxy Survey is measuring around 150 000 redshifts and 15 000 peculiar velocities from galaxies over the southern sky at | b | > 10◦. When complete, it will be the largest survey of its kind by more than an order of magnitude. Here we describe the characteristics of the Second Incremental Data Release (DR2) and provide an update of the survey. This follows earlier data made public in D...
