In The News: Planck Detects Superclusters

"Planck detects new supercluster of galaxies"

Surveying the microwave sky, Planck has obtained its very first images of galaxy clusters, amongst the largest objects in the Universe, by means of the Sunyaev-Zel'dovich effect, a characteristic signature they imprint on the Cosmic Microwave Background. Joining forces in a fruitful collaboration between ESA missions, XMM-Newton followed up Planck's detections and revealed that one of them is a previously unknown supercluster of galaxies.
…
These first images include some clusters that are well known to astronomers, such as Coma, a very hot and nearby cluster extending over more than two degrees in the sky, and Abell 2319, another nearby cluster.
..
The XMM-Newton observations have shown that one of the candidate clusters is in fact a supercluster composed of at least three individual, massive clusters of galaxies, which Planck alone could not have resolved,"
…
"This is the first time that a supercluster has been discovered via the SZE," adds Aghanim. "This important discovery opens a brand new window on superclusters, one which complements the observations of the individual galaxies therein."

Using CMB imprints to detect a new class of Superclusters … interesting.

Warning off topic.

Our EU friends claim that galaxies are formed by giant Birkeland filaments. The filaments are large enough to have an observable Sunyaev-Zel'dovich effect.

No such effect has been observed.
Once again empiricism triumphs over pseudoscience nonsense.

Steven got to them first!!!

Make them walk the Planck

Let's see the EU mob weasel out of this one....no doubt they'll have an "answer" to this.

Seeing as we're no longer visited by them, here's some rope to help 'em out (from the article):

Planck's design, optimised for detecting the SZE signal from clusters scattered throughout the sky, is however not suited for in-depth investigations— its resolution is simply not sufficient to discern much detail for most of them, especially any newly discovered, high-redshift ones.

Yikes !!!

… I think I'm turning Electro-eze, I think I'm turned Electro-eze .. I really think so …

Given the gentlemen are Russian, they might argue the SVE is old communist propoganda.

I thought one of them looked a little like Leonid Brezhnev....the ol' "monobrow" strikes again!!!

Most of their theory sounds like a "5 Year Plan"
