An international group of scientists led by the RIKEN Cluster for Pioneering Research has used observations from the Multi Unit Spectroscopic Explorer (MUSE) at the ESO Very Large Telescope (VLT) in Chile and the Suprime-Cam at the Subaru telescope to make detailed observations of the filaments of gas connecting galaxies in a large, distant proto-cluster in the early universe.

Based on direct observations, they found that, in accordance with the predictions of the cold dark matter model of galaxy formation, the filaments are extensive, extending over more than 1 million parsecs—a parsec being just over three —and are providing the fuel for intense formation of stars and the growth of super within the proto-cluster.

The observations, which constitute a very detailed map of the filaments, were made on SSA22, a massive proto-cluster of located about 12 billion light years away in the constellation of Aquarius, making it a structure of the very early universe.

The findings, published in Science, give new insights into galaxy formation. The dominant belief at one time was that galaxies formed and then organized into clusters in a bottom-up way, but now, it is generally believed that filaments in the universe fueled the formation of clusters of galaxies at places where the filaments crossed, creating dense regions of matter. In accordance with this, the group found that the intersection between the enormous filaments they identified is home to active galactic nuclei—supermassive black holes—and "starbursting" galaxies that have very active star formation. They determine their location from observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) and the W. M. Keck Observatory.

Their observations are based on the detection of what is known Lyman alpha radiation— that is produced when neutral hydrogen gas is ionized and then returns to its ground state—using the MUSE instrument. The radiation was found to be intense—too high to be from the ultraviolet background radiation of the universe. Their calculations indicated that the high radiation was likely triggered by star-forming galaxies and forming black holes.

According to Hideki Umehata of the RIKEN Cluster for Pioneering Research and the University of Tokyo, the first author of the paper, "This suggests very strongly that gas falling along the filaments under the force of gravity triggers the formation of starbursting galaxies and supermassive black holes, giving the universe the structure that we see today.

This movie shows the emission from the filaments identified in the observations using the MUSE instrument at the Very Large Telescope. As the movie progresses, gas at different relative velocities along the line of sight is shown (on a scale where 0 is the velocity at the center of the structure, see top right corner). Stars mark the projected positions of active galaxies. The color map encodes the intensity of the detected radiation, on a scale defined at the top of the image. The movie highlights how galaxies are embedded in these filaments. Credit: Hideki Umehata

"Previous observations had shown that there emissions from blobs of gas extending beyond the galaxies, but now we have been able to clearly show that these filaments are extremely long, going even beyond the edge of the field that we viewed. This adds credence to the idea that these filaments are actually powering the intense activity that we see within the galaxies inside the filaments."

Co-author Michele Fumagalli from Durham University, U.K., said, "It is very exciting to clearly see for the first time multiple and extended filaments in the early . We finally have a way to map these structures directly, and to understand in detail their role in regulating the formation of and galaxies."

That person made a legitimate comment. Why don't you address his concerns instead of talking like a brainless schitthead?

Oct 03, 2019
...the cold dark matter model of galaxy formation, the filaments are extensive

Hmm...filaments eh!
Are they getting closer to seeing the light, or have they gone too far and are now blinded beyond reason?
Perhaps a little sit-down with the fuzzy dark matter guys in the other thread, could help sort things out.

Oct 03, 2019
Filaments in Lyman Alpha, not so far from what I been saying, eh? Magnetic fields of atomic hydrogen and higher metals forming the backbone of the Universe. I keep being proven, even against naysayer's wishes.

Oct 03, 2019
@Troll, you just made my block list. Perhaps you'd care to review the posting record of the individual you're attempting to defend, particularly considering that the original comment was the brainless one, flapping baseless broad accusations. Claims without evidence may be dismissed without evidence. There is no reason posters here on physorg should tolerate abusive comments that are presented without any evidence to support them.

This is legitimate science, with backing observations anyone who wants to challenge them legitimately can attempt to disprove. It's based on a scientific paper accepted for publication because it shows the sources of the observations so they can be checked. Accusing everyone from the scientists who made the observations to publishers of science aggregation sites of being stupid or dishonest is completely wrong and an abuse of this site. Since the moderators will not force posters to keep science, it is entirely appropriate for posters to do so.

Oct 03, 2019
Back to the article, this is interesting confirmation of one hypothesis and rejection of another: galaxies did not form then make filaments, instead filaments channeled matter into galaxy clusters which formed at intersections of the web of filaments according to the dominant LCDM theory. LCDM wins again! And so does relativity.

#Da Schreib

I am not planning to review rodkeh's whole posting history. The only comment I am concerned about is the one that he posted above in this thread which seems to be a legitimate one. Whether or not I agree with it is irrelevant. Your coming to the defense of Castrogiovanni's own words, "More idiocy from eejits! Go away, you clown. Yes?" is a clear indication that you approve of such a dumbass retort that is devoid of any science or explanation of the article. Maybe you yourself might like to explain the science to rodkeh instead?

Oct 03, 2019
@Troll_Terminator

Actually I find Rodkeh's comment offensive.

"More fake science from phys.org...."

He adds nothing to the discussion.

There are people on this site that refuse to accept 1/0 is undefined.
They can't calculate 2 + 2/2 =
They refuse to believe photons carry momentum.
Oh and let's not forget that they believe all free neutrons decay at exactly 14.7 minutes. Like little ticking time bombs.
I could go on and on.

People try to teach them but they aren't here to learn.
They are here for attention.

#jimmybobber

Why are you offended by rodkeh's comment? In what and which way was he referring his comment to you? I didn't read his comment as being addressed to anyone in particular, as a matter of fact. I think that you and Da Schneib are much too sensitive in terms of other people's thoughts and opinions. This website is open to all commentators and their concerns. Why don't you get with rodkeh and explain to him your side of the story.

#jimmybobber

Again I ask you. Why are you offended by rodkeh's comment? I find this sort of emotion quite interesting, especially since the comment only consisted of five words in all. He did not mention any names except for phys.org. And yet you are offended and Da Schneib is defending Castrogiovanni's choice of abusive language.

Oct 03, 2019
@troll, just the same as all the others who troll me by mispeling my handle. Lern to spel. Fuck you in the heart, especially for trying to pass it off as a typo. Maybe you'd care to apologize. But I doubt you have the balls.

Oct 03, 2019
Yes, there seems to be quite a lot of paranoia going on in the minds of Castrogiovanni, Da Schneib and also jimmybobber. To be offended by a simple innocent comment wrt someone's thoughts that was not directed at anyone of the offended in particular is definitely a clear sign of Paranoia. Do any of you carry guns or an AR-15 on your person, by any chance?

Oct 03, 2019
And I still think you're a sock puppet. And you just proved it again. Block doubly confirmed.

Oct 03, 2019
So which is it, Da Schneib. Do you carry a handgun or an AR-15? Certainly not a peashooter, eh?

Oct 03, 2019
"Their observations are based on the detection of what is known Lyman alpha radiation—ultraviolet light that is produced when neutral hydrogen gas is ionized and then returns to its ground state—using the MUSE instrument. The radiation was found to be intense—too high to be from the ultraviolet background radiation of the universe."

Their "observations" were of "hydrogen". Odd how quickly the "predictions of the cold dark matter model of galaxy formation" so quickly evolve into discoveries of huge never before known quantities of ORDINARY MATTER stranding it's tangled webs & gravity throughout the Universe with enough matter to create GALAXY sized stellar masses, YET, still not a scintilla of that dark Cosmic Fairy Dust can be OBSERVED.

Pesky little fella that DM is, knows just when we are looking for it & finds a cosmic cloud to hide behind so we can't see it.

not one of the bunco-artist's sockpuppets?
you need to be less gullible
& learn better judgement

as for this article
while thinking about the early web of filaments...

i am speculating that improving technology will let us discover primeval black holes at many of the nexus of joined filament structures

that the filament structure is a pattern randomly forming out of archaic gases & dusts
being pulled into the shape of webbing by overlapping tidal forces from the multitude of BH nexus

@Troll_Terminator
I do not presume to answer for those of whom you've requested more detail. Instead, in their defence I would ask you to consider the initial post by @rodkeh.

In response to this post, @Castrogiovanni took exception (perhaps inadvisedly using derogatory terms) to the claim that a peer-reviewed science article in a respected Journal, by scientists who are advanced in their professional fields and with a history of well-received published research papers, was "fake science".

This claim is also made in respect of an aggregator site (physorg), which had no input to the science involved, nor in writing the academic paper that was published; @rodkeh's comment was therefore doubly-wrong. It was offensive in terms of maligning the scientists involved as being "fakers"; arguably this is defamatory.

You then said @rodkeh's post was "a legitimate comment"; when @Da Schneib provided a well-reasoned reply to you, you criticise him too.

Your replies seem inappropriate.

.......well then, you're sudden conversion that "improving technology" may someday lead to the discovery of "primeval black holes, so try this also:

In the last century Cosmologists fixed the quantity of the Intergalactic Medium of Ordinary Matter at 1 atom/m³ & DM at 0.3 particles/cm³. Along comes 21st Century spectroscopy & scientists discover there is minimally 1 atom of hydrogen or helium per cm³ (not counting sub-atomic particles) of the IGM & way more than that inside the ISM.

With hydrogen/helium atoms now PROVEN to exist at a ratio of more than 3 to 1, this reduces the old speculated concentration of DM ratio over OM from more than 5:1 to more than 3:1 of OM over DM, suddenly the so-called inferred gravity imbalance of DM over OM switches doesn't it & there remains no PROVABLE evidence that the smallest particle of DM exists.

Oct 04, 2019
@Benni

What you wrote is unintelligible.

"With hydrogen/helium atoms now PROVEN to exist at a ratio of more than 3 to 1, this reduces the old speculated concentration of DM ratio over OM from more than 5:1 to more than 3:1 of OM over DM, suddenly the so-called inferred gravity imbalance of DM over OM switches doesn't it & there remains no PROVABLE evidence that the smallest particle of DM exists."

Also you may want to refer to the density of dark matter particles as an average within a certain radius. Just some advice.


Oct 04, 2019
By the way my comments were removed for cross-posting from another thread. I received messages from physorg explaining it.

I assume the moderator is not a human being.

Anyways, its always nice to see observations matching predictions.

"accordance with the predictions of the cold dark matter model of galaxy formation"


Since about 2016, 21st spectroscopy measurements has substantiated the validity of changing the density of Ordinary Matter per cm³ of the IGM from 1 atom of hydrogen/helium per m³ of the IGM to that of 1 atom/cm³, but that doesn't catch your attention does it?

Change the density of one type of mass in comparison to another & off the rails goes the original hypothesis of that 5:1 ratio of DM over Ordinary Matter. The consequence of these new measurements necessitates changes in the so-called "inferred gravity" standard credited to DM, but 20th dinosaurs like you don't like revised data because it changes your archaic models forever dooming you to remain stuck in your old Pop-Cosmology fantasyland.

what does it matter, especially if any of the person(s) in question reside in the US?

were you going for ad hominem with a hope that you can elicit fear? or were you attempting defamation due to ignorance and lack of ability to research?

And? I thought we were talking about the IGM (intergalactic medium)? This is the interstellar medium! About 1 per cc sounds right, and has been known for some years. This, for instance, is from 1999;

So, I fail to see your point. Assuming you have one.

Oct 04, 2019
Earth calling Benni, Earth calling Benni! Are we talking about the IGM or the ISM? And the IGM is nowhere near 0.1 per cc. That sounds like the interstellar wind. Which is about right. 1.0 is the average for the ISM, which includes dense clouds and such.

Summary: Benni hasn't got a clue what he's talking about. As usual. Anybody surprised? Rhetorical.
