New radio imaging technique lets us see right through Milky Way'sdisk, at galaxies on the other side!

An extension to the survey was published in 2005: http://iopscience.iop.org/article/10.1086/426320/ About half the galaxies were already known, but the data give new definition to the "Norma Wall" in the direction of the Great Attractor and also show several other galaxy groupings. Wow, that's some lax publication deadlines if all of this stuff was found out back in 2000 & 2005! I googled Norma Wall, it doesn't come back with anything useful. What is it? Yousuf Khan |

I find this the earliest paper that referred to it on arxiv.org, with a handfull of papers that return on a search for it: http://arxiv.org/abs/astro-ph/9705152 David A. Smith |

Also see Fig 18 in the preprint of the current work. "ZOA" is Zone of Avoidance, i.e., near the Milky Way plane. An ADS search for "Norma Wall" in the abstract turned up only three papers (not including the one under discussion or the survey extension mentioned earlier). Oddly, the one dlzc found didn't turn up in that search, so probably more papers exist. This region is difficult to study. -- Help keep our newsgroup healthy; please don't feed the trolls.
