Galaxies grow by accumulating gas from their surroundings and converting it to stars, but the details of this process have remained murky. New observations, made using the Keck Cosmic Web Imager (KCWI) at the W. M. Keck Observatory in Hawaii, now provide the clearest, most direct evidence yet that filaments of cool gas spiral into young galaxies, supplying the fuel for stars.

"For the first time, we are seeing filaments of gas directly spiral into a galaxy. It's like a pipeline going straight in," says Christopher Martin, a professor of physics at Caltech and lead author of a new paper appearing in the July 1 issue of the journal Nature Astronomy. "This pipeline of gas sustains star formation, explaining how can make stars on very fast timescales."

For years, astronomers have debated exactly how gas makes its way to the center of galaxies. Does it heat up dramatically as it collides with the surrounding hot gas? Or does it stream in along thin dense filaments, remaining relatively cold? "Modern theory suggests that the answer is probably a mix of both, but proving the existence of these cold streams of gas had remained a major challenge until now," says co-author Donal O'Sullivan (MS '15), a Ph.D. student in Martin's group who built part of KCWI.

KCWI, designed and built at Caltech, is a state-of-the-art spectral imaging camera. Called an integral-field unit spectrograph, it allows astronomers to take images such that every pixel in the image contains a dispersed spectrum of light. Installed at Keck in early 2017, KCWI is the successor to the Cosmic Web Imager (CWI), an instrument that has operated at Palomar Observatory near San Diego since 2010. KCWI has eight times the and 10 times the sensitivity of CWI.

"The main driver for building KCWI was understanding and characterizing the cosmic web, but the instrument is very flexible, and scientists have used it, among other things, to study the nature of dark matter, to investigate black holes, and to refine our understanding of ," says co-author Mateusz (Matt) Matuszewski (MS '02, Ph.D. '12), a senior instrument scientist at Caltech.

The question of how galaxies and stars form out of a network of wispy filaments in space—what is known as the cosmic web—has fascinated Martin since he was a graduate student. To find answers, he led the teams that built both CWI and KCWI. In 2017, Martin and his team used KCWI to acquire data on two active galaxies known as quasars, named UM 287 and CSO 38, but it was not the quasars themselves they wanted to study. Nearby each of these two quasars is a giant nebula, larger than the Milky Way and visible thanks to the strong illumination of the quasars. By looking at light emitted by hydrogen in the nebulas—specifically an atomic emission line called hydrogen Lyman-alpha—they were able to map the velocity of the gas. From previous observations at Palomar, the team already knew there were signs of rotation in the nebulas, but the Keck data revealed much more.

"When we used Palomar's CWI previously, we were able to see what looked like a rotating disk of gas, but we couldn't make out any filaments," says O'Sullivan. "Now, with the increase in sensitivity and resolution with KCWI, we have more sophisticated models and can see that these objects are being fed by gas flowing in from attached filaments, which is strong evidence that the cosmic web is connected to and fueling this disk."

Martin and colleagues developed a to explain the velocities they were seeing in the gas and tested it on UM287 and CSO38 as well as on a simulated galaxy.

"It took us more than a year to come up with the mathematical model to explain the radial flow of the gas," says Martin. "Once we did, we were shocked by how well the model works."

The findings provide the best evidence to date for the cold-flow model of galaxy formation, which basically states that cool gas can flow directly into forming galaxies, where it is converted into stars. Before this model came into popularity, researchers had proposed that galaxies pull in gas and heat it up to extremely high temperatures. From there, the gas was thought to gradually cool, providing a steady but slow supply of fuel for stars. In 1996, research from Caltech's Charles (Chuck) Steidel, the Lee A. DuBridge Professor of Astronomy and a co-author of the new study, threw this model into question. He and his colleagues showed that distant galaxies produce stars at a very high rate—too fast to be accounted for by the slow settling and cooling of hot gas that was a favored model for young galaxy fueling.

"Through the years, we've acquired more and more evidence for the cold-flow model," says Martin. "We have nicknamed our new version of the model the 'cold-flow inspiral,' since we see the spiraling pattern in the gas."

"These type of measurements are exactly the kind of science we want to do with KCWI," says John O'Meara, the Keck Observatory chief scientist. "We combine the power of Keck's telescope size, powerful instrumentation, and an amazing astronomical site to push the boundaries of what's possible to observe. It's very exciting to see this result in particular, since directly observing inflows has been something of a missing link in our ability to test models of galaxy formation and evolution. I can't wait to see what's coming next."

The new study, titled, "Multi-filament gas inflows fuelling young star-forming galaxies," was funded by the National Science Foundation (NSF), the W. M. Keck Observatory, Caltech, and the European Research Council.

cant vividly displaying his complete lack of integrity & scientific knowledge.

cant, where are the electric outlets you are dependent on?
in the"structure"of Space/Time?

cause you are going to have to plug your fanciful wiring into something besides the Aether.

I'm guessing no one's been cruel enough to explain to you
that you "pull" a rope?
you won't get much work done if you continue to "push" that rope in your hands.

The arms/filaments are a direct consequence of both chaos/turbulence phenomena and the self-shading phenomena that arises around any massive collection of gas/dust of any appreciable density sufficient to 'block' otherwise heating/ionising radiation from reaching into and through that massive collection. So in fact the gravitational effects which 'anchor' the persistent swirling feature is the 'sustaining' actor; then along comes the E-M plasma/currents effects along the outer ionised/hotter boundary layers/surface of those 'denser, self-shading filaments' formed/sustained by Gravitational 'anchoring' to the whole colossal galactic swirl.

ps: @cantdrive.

It is a Gravitational-EM HYBRID phenomena. Eg, now consider a White Dwarf 'cannibalising' its companions mass via in-spiralling/accretion disc of material formed due to WD's Gravity. Once that Gravitational 'drain' is established, all sorts of 'currents' arise. :)

Jul 01, 2019
There are some very complicated issues of galaxy formation. Unfortunately, here is the same problem as with the stars. The origin of galaxies remains unclear, in spite of huge activity in the field. What the "formation" means? It means that we have the material that is assembling into galaxies.

Mate! You and I both know how 'simulations' can mislead if UN-real assumptions/Inputs go into their formulation. Yes? And I just explained to you where LAB experiments need UNDERLYING SOLID materials/circuitry/control 'accessories' for stabilising lab-created/maintained plasmoids; so they are NOT 'free space plasmoids', are they? :)

Hence why we observe BH-Gravity-anchored plasma accretion disc/polar jets phenomena due to Gravity-EM HYBRID dynamics; else such phenomena would not be able to persist so long, since the E-M forces without Gravity 'anchoring' would destabilise/destroy the 'central feature' in our galaxy IF it WAS "just a plasmoid".

I asked first. But since you have no answer to my query, and instead have chosen to invoke the 'same token' technique, I will tell you this.
Thoughts are formulated in the Mind by the neurons, synapses and other communication paths within the brain. However, those thoughts are formulated in a certain way by the brain so that they can be processed as to levels of importance, etc.
But those thoughts did not originate in the brain, and are conceived through the aether, which is a Medium that transmits. Such as Mind-reading.

Wrong on all counts. Peratt's simulations do not match observed galaxies. Gravity causes BH jets as matter falls onto the accretion disk. And plasmoid woo cannot explain BHs. Three strikes and you're out. Bye loser.

Jul 02, 2019
"Gravity causes BH jets as matter falls onto the accretion disk."
says Castrojonesy

That must be some very weak gravity if it allows the Black Hole jets to shoot out into space, being that those jets are composed of Matter/Energy. If gravity was responsible for attracting Matter into the accretion disc, then that gravitational attraction should be strong enough to hold Matter from being propelled outward from the BH and/or disc. Spewing Matter out into space through polar jets doesn't seem much like gravity at work. Unless gravity is countered by another Force that allows Matter to spew out in polar jets. Perhaps the jets are a "release valve" to allow excess Matter to escape?


Jul 02, 2019
Here is an explanation of "Relief Valves" or Release Valves:

https://www.grain...ve-guide

And from Wiki: "In high-pressure gas systems, it is recommended that the outlet of the relief valve is in the open air. "

The Black Hole polar jets should not exist if the gravity strength was great enough to keep everything within the disc or the BH. Since Matter is allegedly almost continuously pulled into the disc, the jets may be acting as the "relief valves". Thermodynamics at work.

And those "formulation" events (electric signals, per CD) occurred in a causally sequential way, not all in the same moment. Your final summary thoughts are a hierarchaly structured combination of previous signals. And it all took "time".

Nope, observation. In real spiral galaxies the space between the more luminous arms is only a little less dense than the arms. That did not happen in Peratt's woo. Also, he thought double-lobed radio galaxies were two Birkeland currents that went on to form spiral galaxies! Lol.
And the accretion disks of black holes are most certainly due to the massive object they surround. Lots of interesting stuff ablot magnetic fields getting tangled up and launching the jets, but without gravity to feed the disk nothing happens.
And plasmoid woo cannot explain BHs! Stellar orbits and gravitational redshift, remember? Where is it written up?

Jul 02, 2019
The argumentation in favor of electrosity/plasmahooey/etc. as fundamental in cosmic features, great and small, is suspect enough that if research findings determined unequivocally that galaxies were fed by streams of ice-cubes one could imagine the objection:

'I see nothing in that finding that an ice-cube can't have an essentially plasma-form.'
'Obviously ice-lattices are held together by electron-sharing. Guess what, idiot, electrons are CHARGED particles, check any high-school physics textbook.'
_______________

What is it about cold streams of gas that is so hard to understand? The evidence is mounting. Certainly by now everyone has also read that large-scale features have been eerily modeled with considerable precision by a neural network in which the only field governing the input data is gravity. No plasma, no magnetic currents, no electrostatic charge, no electrostatic discharge. Cold, sober, gravity.

@Castrogiovanni
@cantdrive85.

How many times do you BOTH have to be reminded? The central feature in our galaxy is a HYBRID phenomena involving interplay of BOTH Gravity AND E-M; to produce the PROCESS which arises/evolves due to BOTH those forces, with one or the other being the determinant of formation/evolution, at their respective strengths and stages, of the WHOLE long-lasting 'hybrid forces' process/feature.

Again, the initial diffuse matter in the universe was in plasma form; then cooling, electrostatic and gravitational aggregation dynamics creates (eventually) EXTREME Gravitational features which FURTHER aggregated, 'anchored' and STABILISED the HYBRID FEATURE in question; with the torus of material magnetic field PATTERN sorting, accelerating and redirecting SOME of the accretion disc material INWARDS to central 'anchoring/stabilising Gravitational BH body, while MUCH of the rest being redirected OUTWARDS via polar jets observed.

So stop being so 'one-eyed' guys! :)

It is a massive object that forms purely due to gravity. The orbits of the stars around the BH are purely due to gravity. Go look up Kepler's third law. There are no EM terms in there.

I was speaking of the larger picture, including the initial forces/matter 'evolutionary' interactions that create such extreme gravitational/e-m hybrid phenomena as observed..ie, both the extreme Gravitational 'anchor/stabiliser' for the formation/sorting/ingesting(by BH) and expelling (as polar jets) via the overall Electro-Magnetic forces/field patterns that evolve as part of the whole process.

Lol, what a thoroughly brainwashed little EU moron you are! And a black hole twisting a magnetic field to hell and back will do the same. The difference is, woo boy, that we see the predicted EH from the BH. We see stellar orbits commensurate with a BH. We see the expected gravitational redshift from a BH. Plasmoid woo can explain none of that. Its loony proposers have had ~ 35 years since the idiot Lerner first wrote this crap in a non-astrophysics journal (Laser & Particle Beams! Lol!), and neither he, nor any other crackpot has responded to the continuing observations of BHs in that time, and attempted to explain the stellar orbits or redshift. It was a dumb idea in the 80s. It is even dumber now.

my perception
is that the commentators are confusing the timing of events.
Gravity is the triggering mechanism.

think of it as firing a pistol.
Gravity is the pistol & the shooter.
as your finger contracts the trigger, slamming the hammer down on the percussion cap is all Gravity.
which sets off the a chemical explosion
that propels the bullet racing from the barrel
that is the electro-magnetic stage
the bullet flies away
whether it be material rock/ice
or energy photons/cosmic rays

the loud clap of the gunshot

exactly the same phenomena, on a much larger scale
we see as accretion disks, polar jets, demolition derby scrums
as the cartridge is fired there is additional ancillary effects of
a bright flash of burning chemicals
that is similar to what we observe as plasma

But, but, but...you STILL ignore the physically proven reality that PLASMOIDS EXPLODE unless their inherently unstable dynamics are stabilised/anchored and maintained over long periods via some solid structures/controls (as provided in lab setups) or via some sufficiently strong central gravitational feature (as occurs in the centre of our galaxy).

Gravitational 'anchor/stabiliser' for the formation/sorting/ingesting(by BH) and expelling (as polar jets) via the overall Electro-Magnetic forces/field patterns that evolve as part of the whole process. That's it.

News flash! Plasmoids create jets, gravity is inconsequential in the process, as shown in laboratory experiments.

Lab experiments performed in - Earth's gravitational field...
But who cares about real science when you can conjure fantastical gravity monsters to do the job.

It makes more sense than conjured electric plasma ones...

That's what preconceived beliefs can do, convince folks that real processes are less viable than fictional maths conjecture.


You don't have a viable process! Just fairy tales from cranks. Show us how plasmoid woo is causing the observed stellar orbits. And producing gravitational redshift. Unless and until one of your cranks can do that, it remains pure woo.
