Astronomers No Longer Need To Avoid the "Zone of Avoidance" 75

Posted by yaelk from the dont-avoid-it dept.
An anonymous reader writes: If you want to look out into the Universe, all you need to do is gather the light it gives off. Unless, of course, there's something in the way. For about 20% of the sky, that's exactly the story. In our own Milky Way galaxy, the neutral gas and dust block most of the visible light everywhere we look, preventing us from observing the Universe beyond. However, although the gas and dust might block visible light, longer wavelengths like radio and infrared can pass right through. Recently NASA's Wide-field Infrared Survey Explorer (WISE) mission mapped the entire sky in the infrared, including the entire galactic plane. It not only found many background galaxies, but it gave us a new window into what's possible. Perhaps, with future missions, we'll discover the cause of the "great attractor" phenomenon after all.

      Why do people hate SwaB links? They usually have pretty good science content written in a way that most people can readily understand.

      No, not exactly an academic journal, and yeah, fuck Forbes, but I don't think it realistic to expect Slashdot (or any mostly ad supported site) to blacklist another site just because they use an anti-adblocker.

      So, other than the standard "we just love to bitch", why all the hate?
      • Because the Forbes site has been shown to serve malware in the ads that they serve, and they require you to disable adblockers, which means you will get malware if you visit their site and turn off your adblockers.

          No, that can't explain it. The annoyance with StartsWithABang started far before that happened. People gave him a lot of grief when he was simply linking to his own blog.

          I'll admit I tend to dislike seeing a member that does NOTHING but post submissions to the site, never even engaging in the discussion that follows. To me, that smacks of "I'm trying to get my visitor count up, but I don't give a shit about what the members have to say." Maybe others don't agree, but I probably wouldn't mind if an author regularly engaged with the community after posting summaries and links to their own articles, so long as they were interesting and relevant to this demographic. If you check out StartsWithABang's history, it was almost 100% submissions. He never appeared interested in discussing the articles he wrote, so it's not hard to understand why he didn't exactly endear himself to the community.

          Contrast that to our new overlords, who have shown to be actually willing to talk to people here, and importantly, to listen to what they have to say in return. That's the essence of slashdot. The news and articles are just a way to get the discussions rolling.

          • Personally, I liked startswithabang medium.com articles -- but can't stand forbes links. Granted lots of people hated his pre-forbes submissions but not all of us.

            • I actually liked some of his articles, as they seems reasonably approachable for lay-persons like myself who are mildly interested in astronomy. A lot of people complained about medium.com, but I never quite understood what the beef was there. As I stated, my issue is with people that post articles and never follow up with any discussion, and he's sort of a poster-child for that. But on the "don't care" to "flaming tirade" scale of concerns, it's still pretty low.

              I mean, he's certainly no Bennett Haselto

              • I agree, I didn't mind the Medium.com articles - yes, they pushed the envelope of current browsers with fancy CSS transitions and large bandwidth images - but the articles were informative and pretty.

                I also agree that submitters should engage in the discussion, but to be fair, Medium.com had it's own discussion. Of course /. is a much better forum, but it didn't bother me that much. It seems no different to me if some random AC had posted the links to StartsWithABang articles.

  • Forbes has chosen to speed their journey into irrelevance with their policies. Don't force Slashdot to follow them down that hole by becoming dependent upon their content.

  • First, while WISE is an improvement in the whole "zone of avoidance" phenomenon, it's not perfect. It's resolution was rather low, so even though it could peer through the dust, the glare of foreground stars in the Milky Way still hid a significant fraction of the sky.

    Second, there's a proposed solution to the "great attractor" already. It's the galaxy super cluster named Laniakea.

    Astronomers no longer need to avoid...? Really? I'll just point my telescope there and see all the new galaxies now.

    The Parkes HI Zone of Avoidance Survey

    Abstract: A blind HI survey of the extragalactic sky behind the southern Milky Way has been conducted with the multibeam receiver on the 64-m Parkes radio telescope. The survey covers the Galactic longitude range 212 degrees to 36 degrees and Galactic latitudes |b| less than 5 degrees to an rms sensitivity of 6 mJy per beam per 27 kmsâ'1 channel, and yields 883 galaxies to a recessional velocity of 12,000 kmsâ'1. The survey covers the sky within the HI Parkes All-Sky Survey (HIPASS) area to greater sensitivity, finding lower HI-mass galaxies at all distances, and probing more completely the large-scale structures at and beyond the distance of the Great Attractor. Fifty-one percent of the HI detections have an optical/near-infrared (NIR) counterpart in the literature. A further 27% have new counterparts found in existing, or newly obtained, optical/NIR 1 images. The counterpart rate drops in regions of high foreground stellar crowding and extinction, and for low-HI mass objects. Only 8% of all counterparts have a previous optical redshift measurement. The HI sources are found independently of Galactic extinction, although the detection rate drops in regions of high Galactic continuum. The survey is incomplete below a flux integral of approximately 3.1 Jy kmsâ'1 and mean flux density of approximately 21 mJy, with 75% and 81% of galaxies being above these limits, respectively. Taking into account dependence on both flux and velocity width, and constructing a scaled dependence on the flux integral limit with velocity width (w0.74), completeness limits of 2.8 Jy kmsâ'1 and 17 mJy are determined, with 92% of sources above these limits. A notable new galaxy is HIZOA J1353â'58, a possible companion to the Circinus galaxy. Merging this catalog with the similarly-conducted northern extension (Donley et al. 2005), large-scale structures are delineated, including those within the Puppis and Great Attractor regions, and the Local Void. Several newly-identified structures are revealed here for the first time. Three new galaxy concentrations (NW1, NW2 and NW3) are key in confirming the diagonal crossing of the Great Attractor Wall between the Norma cluster and the CIZA J1324.7-5736 cluster. Further contributors to the general mass overdensity in that area are two new clusters (CW1 and CW2) in the nearer Centaurus Wall, one of which forms part of the striking 180â--¦ (100hâ'1Mpc) long filament that dominates the southern sky at velocities of â¼ 3000 kmsâ'1, and the suggestion of a further Wall at the Great Attractor distance at slightly higher longitudes.
