The river
We are in the middle of a river flowing at around 400 Km/sec in the
direction of Galactic l = 282 degree (+/- 11) and b = 6 degree (+/- 6) http://arxiv.org/abs/0911.5516 That article is completely mind blowing. |

I have just tried (again) and it works without problems |

Regards Jurgen I had no trouble downloading the full paper just now: go to the url Jacob Navia gave, and in the top right corner of the page there are download links for "PDF", "Postscript", and "Other formats". More generally, arXiv policy is that all arXiv preprints be freely accessible, so if a paper on arXiv.org is truly inaccessible, that's a technical failure, a.k.a. bug (which, if confirmed, should be reported to the arXiv administrators). ciao, -- -- "Jonathan Thornburg [remove -animal to reply]" Dept of Astronomy, Indiana University, Bloomington, Indiana, USA "Washing one's hands of the conflict between the powerful and the powerless means to side with the powerful, not to be neutral." -- quote by Freire / poster by Oxfam |

Thank you all very much, also for several eMails. I do not understand why I did not see the way to the link. Regards Jurgen |

Nobody comments that? The whole visible universe is moving at 400 Km/sec in a single direction (700 clusters of galaxies measured), and nobody says anything? Or maybe everybody is just speechless like me... :-) jacob |

First, it can't be the ENTIRE visible universe, since motion implies a reference. Second, it has been known for a long time that we (meaning at least the Local Group) are moving as part of a large-scale bulk flow. The magnitude and direction are compatible with the observed CMB dipole. What is QUALITATIVELY new in this paper? |

Nobody comments that? The whole visible universe is moving at 400 Km/sec in a single direction (700 clusters of galaxies measured), and nobody says anything? First, it can't be the ENTIRE visible universe, since motion implies a reference. The reference is the CMB. I cite the national geographic article Hot gas in galaxy clusters warms the microwave background radiation, and a very tiny component of this temperature fluctuation also contains in itself information about cluster velocity If a cluster were moving faster or slower than the universe's background radiation, you'd expect to see the background heated slightly in that region of the universe—the result of a sort of electron-scattering "friction" between the cluster's hot gas and particles in the background radiation. Because these fluctuations are so faint, the team studied more than 700 galaxy clusters. Second, it has been known for a long time that we (meaning at least the Local Group) are moving as part of a large-scale bulk flow. The magnitude and direction are compatible with the observed CMB dipole. What is QUALITATIVELY new in this paper? The fact that is not the local group but 700 galaxy clusters that are moving... I could be wrong of course, I am not a professional. Please take my opinions with caution. |

The fact that is not the local group but 700 galaxy clusters that are moving... We are part of the Virgo supercluster, which the Wikipedia says has at least 100 galaxy clusters: http://en.wikipedia.org/wiki/Virgo_Supercluster It also says it is one of millions of superclusters in the observable universe. According to some astronomers, one do not see larger structures, "hyperclusters", than superclusters, or beyond about one to two billion light years in diameter http://en.wikipedia.org/wiki/Supercluster So if they really studied 700 clusters, and not superclusters, that is just a part of a few nearby superclusters. Even if it were 700 superclusters, it would still be a tiny part of the observable universe. Perhaps it means that some of the nearby superclusters have a common motion. Hans |

It seems that this relates to observations going back to 2008 and already discussed in a contrubution of the English Wikepedia http://en.wikipedia.org/wiki/Dark_flow and there called "Dark Flow". This news has already found its way to the German broadcasting program Deutschlandfunk at http://www.dradio.de/dlf/sendungen/forschak/1118326/ where you can not only read the text but also listen to the original broadcast. - Well, this is only for people who understand German. Does the Wikipedia article report on the same topic as your link did? All the best Jurgen [Mod. note: quoted text trimmed -- mjh] |
