1 Jun 2004 | | Subject: | astro-ph | | Affiliation: | 1,2), Patrick A. Woudt , Heinz Andernach , ( Dept. of Astronomy, University of Guanajuato, Institute of Astronomy, UNAM, Dept. of Astronomy, University of Cape Town | | Abstract: | Motivated by the possibility that the highly obscured (A_B = 12 mag) radio galaxy PKS 1343-601 at (l,b,cz) = (309.7, +1.8, 3872km/s) might constitute the center of a heavily obscured cluster in the Great Attractor region, we have imaged about 2 x 2 degree of the core of this prospective cluster in the I-band using the WFI at the ESO 2.2m telescope at La Silla. We were able to identify 49 galaxies and 6 uncertain galaxy candidates. Although their distribution does not resemble a centrally condensed, massive cluster, its appearance -- severely influenced by the strong dust gradient across our surveyed region -- is entirely consistent with a cluster. | | Source: | arXiv, astro-ph/0406044 | | Services: | Forum | Review | PDF | Favorites | |
