Extragalactic Large - Scale Structures behind the Southern Milky Way . – I . Redshifts Obtained at the SAAO in the Hydra / Antlia Extension ⋆
Spectroscopic observations have been carried out for galaxies in the Milky Way with the 1.9 m telescope of the South African Astronomical Observatory (SAAO). The galaxies were selected from a deep optical galaxy search covering 266 ∼< l ∼< 296 , |b| ∼< 10 ◦ (KraanKorteweg 1994). This is in the extension of the Hydra and Antlia clusters and in the approximate direction of the dipole anisotropy i...
متن کاملExtragalactic large-scale structures behind the southern Milky Way III. Redshifts obtained at the SAAO in the Great Attractor region
In the third of a series of papers on large-scale structures behind the southern Milky Way, we report here on redshifts obtained at the South African Astronomical Observatory (SAAO) in the Great Attractor region (318 deg <∼ ` <∼ 340 deg, |b| ≤ 10 deg, Woudt 1998). This region encompasses the peak in the reconstructed mass density field, associated with the Great Attractor (Kolatt et al. 1995, D...
متن کاملThe Universe behind the Southern Milky Way
A first analysis of a deep blind HI survey covering the southern Zone of Avoidance plus an extension towards the north (196 ≤ l ≤ 52) obtained with the Multibeam receiver at the 64m Parkes telescope reveals slightly over a thousand galaxies within the latitude completeness limit of |b| ≤ 5. The characteristics and the uncovered large-scale structures of this survey are described, in particular ...
متن کاملOverview of Uncovered and Suspected Large-scale Structures behind the Milky Way
Various dynamically important extragalactic large-scale structures in the local Universe lie behind the Milky Way. Most of these structures (predicted and unexpected) have only recently been made ‘visible’ through dedicated deep surveys at various wavelengths. The wide range of observational searches (optical, near infrared, far infrared, radio and X-ray) for galaxies in the Zone of Avoidance (...
متن کاملLarge-scale Structures behind the Milky Way from Near-ir Surveys
About 25% of the optical extragalactic sky is obscured by the dust and stars of our Milky Way. Dynamically important structures might still lie hidden in this zone. Various approaches are presently being employed to uncover the galaxy distribution in the Zone of Avoidance (ZOA) but all suffer from (different) limitations and selection effects. We investigated the potential of using the DENIS NI...
