(PhysOrg.com) -- An international team of astronomers has used the brief but brilliant light of a distant gamma-ray burst as a probe to study the make-up of very distant galaxies. Surprisingly the new observations, made with ESOs Very Large Telescope, have revealed two galaxies in the young Universe that are richer in the heavier chemical elements than the Sun. The two galaxies may be in the process of merging. Such events in the early Universe will drive the formation of many new stars and may be the trigger for gamma-ray bursts.
Gamma-ray bursts are the brightest explosions in the Universe. They are first spotted by orbiting observatories that detect the initial short burst of gamma rays. After their positions have been pinned down, they are then immediately studied using large ground-based telescopes that can detect the visible-light and infrared afterglows that the bursts emit over the succeeding hours and days. One such burst, called GRB 090323, was first spotted by the NASA Fermi Gamma-ray Space Telescope. Very soon afterwards it was picked up by the X-ray detector on NASA's Swift satellite and with the GROND system at the MPG/ESO 2.2-metre telescope in Chile and then studied in great detail using ESO's Very Large Telescope (VLT) just one day after it exploded.
The VLT observations show that the brilliant light from the gamma-ray burst had passed through its own host galaxy and another galaxy nearby. These galaxies are being seen as they were about 12 billion years ago. Such distant galaxies are very rarely caught in the glare of a gamma-ray burst.
"When we studied the light from this gamma-ray burst we didn't know what we might find. It was a surprise that the cool gas in these two galaxies in the early Universe proved to have such an unexpected chemical make-up," explains Sandra Savaglio (Max-Planck Institute for Extraterrestrial Physics, Garching, Germany), lead author of the paper describing the new results. "These galaxies have more heavy elements than have ever been seen in a galaxy so early in the evolution of the Universe. We didn't expect the Universe to be so mature, so chemically evolved, so early on."
As light from the gamma-ray burst passed through the galaxies, the gas there acted like a filter, and absorbed some of the light from the gamma-ray burst at certain wavelengths. Without the gamma-ray burst these faint galaxies would be invisible. By carefully analysing the tell-tale fingerprints from different chemical elements the team was able to work out the composition of the cool gas in these very distant galaxies, and in particular how rich they were in heavy elements.
It is expected that galaxies in the young Universe will be found to contain smaller amounts of heavier elements than galaxies at the present day, such as the Milky Way. The heavier elements are produced during the lives and deaths of generations of stars, gradually enriching the gas in the galaxies. Astronomers can use the chemical enrichment in galaxies to indicate how far they are through their lives. But the new observations, surprisingly, revealed that some galaxies were already very rich in heavy elements less than two billion years after the Big Bang. Something unthinkable until recently.
This artists impression shows two galaxies in the early Universe. The brilliant explosion on the left is a gamma-ray burst. As the light from the burst passes through the two galaxies on the way to Earth (outside the frame to the right) some colours are absorbed by the cool gas in the galaxies, leaving characteristic dark lines in the spectrum. Careful study of these spectra has allowed astronomers to discover that these two galaxies are remarkably rich in heavier chemical elements. Credit: ESO/L. Calçada
The newly discovered pair of young galaxies must be forming new stars at a tremendous rate, to enrich the cool gas so strongly and quickly. As the two galaxies are close to each other they may be in the process of merging, which would also provoke star formation when the gas clouds collide. The new results also support the idea that gamma-ray bursts may be associated with vigorous massive star formation.Energetic star formation in galaxies like these might have ceased early on in the history of the Universe. Twelve billion years later, at the present time, the remains of such galaxies would contain a large number of stellar remnants such as black holes and cool dwarf stars, forming a hard to detect population of "dead galaxies", just faint shadows of how they were in their brilliant youths. Finding such corpses in the present day would be a challenge.
"We were very lucky to observe GRB 090323 when it was still sufficiently bright, so that it was possible to obtain spectacularly detailed observations with the VLT. Gamma-ray bursts only stay bright for a very short time and getting good quality data is very hard. We hope to observe these galaxies again in the future when we have much more sensitive instruments, they would make perfect targets for the E-ELT," concludes Savaglio.
More information: This research was presented in a paper "Super-solar Metal Abundances in Two Galaxies at z ~ 3.57 revealed by the GRB 090323 Afterglow Spectrum" to appear in Monthly Notices of the Royal Astronomical Society.

By now it should be clear. The use of the word "surprise" basically means that the big bang assumptions have been falsified really badly. Just about every new observation does this, yet big bang continues to hang around in the minds of the research fraternity - awaiting final destruction by some really intrepid soul.

Close to that same as the core as we can see that matches the nebulae that stars form in.
For which you have no evidence just a desire for it to be true so you manufacture evidence based on the theory that the Sun has a neutron core which is circular reasoning.
Which is contrary to the evidence. The smallest pulsars are all more massive than the Sun.
And it is all dependent on a magic supernova that somehow keeps the metals in the inner solar system despite ALL known supernova blasting out most of the debris into interstellar space. Neither you nor anyone else even has the beginning of a wild assed guess as to how a supernova would not disperse most of the metals into interstellar space.

Here is more that you have never made an actual reply to.
You insist there is such a thing as neutron repulsion. You insist it is strong enough to stop the formation of black holes, not just stellar black holes but ALL black holes no matter what the size. Also it you claim it is long ranged enough to sunder galaxies. Though you refuse to answer any question about its actual strength or range those claims make it clear that it MUST be more powerful than gravity per unit of mass even if the mass is mostly hydrogen atoms as we can see makes up most the mass in the in the Universe, based on your denial of Dark Matter that is.
It really doesn't require a great deal of effort to notice that there is a severe problem with that set of claims. They make galaxies, stars, even neutron stars, planets and pretty much everything held together by gravity impossible.>>

And conversely, a new paper posted recently on arXiv has again looked at the possibility that an ancient supernova seeded the primordial cloud that eventually collapsed to form our solar system: http://arxiv.org/...12v1.pdf
Using hydrodynamic models these researchers found that a supernova would be able to both initiate collapse of and sufficiently enrich a 10 solar mass gas cloud with Al26 (within ~5pc, similar to the environment found in some young star clusters; M16 is referenced).
While not the first study examine this scenario, it does underscore some of the advances being made in the study of the birth of the solar system.

Bound neutrons do not decay. Free neutrons and neutrons in unstable nuclei yes, but actually bound no. The neutrons in a neutron star are bound by pressure so strong that protons merge with and electron and a neutrino and some energy to form the neutrons. Protons from the decay of neutrons would just be forced back into a neutron.
We can see pulsars, the Crab has one. They show no signs of this alleged decay. Plus Oliver is quite insistent that the Sun HAS a pulsar in it. Not had, HAS.

And there is no evidence that it is decaying. No reason to believe it should either as it would be contrary to how the neutronium forms from the pressure of gravity.
Four and half billion years in our past. Around 16 rotations of the galaxy ago. Not likely to be in our neighborhood anymore and not likely to be visible unless very close.
No. They aren't going to make the gravitational pressure disappear.
Not one single neutron that is bound in a stable atom has ever been detected to decay. If one did so the pressure would just force the proton to merge with the first available electron.

We knew exactly were the Crab pulsar was but it wasn't seen in visible light till recently those farther will be more difficult. We also know that at least one type IIa supernova has no detectable pulsar in the remains, 1987a. That means it either black holed, and Oliver says this cannot happen, or pulsars have a directional component to the radio beams and that 1987a is not pointed in our direction. So either Oliver is wrong and black holes exist or there are many pulsars that are invisible even when they are new.>>

There is a possibility that the Crab pulsar has a planet. But there has been no confirmation in the succeeding 40 years. If there is one it would be a remnant of something from before the Supernova as it has been way too short a time for anything to form anew.

They are similar but NOT the same. For one thing that is the matter from the supernova. I said nothing about the matter in the rest of system and that was intentional. Planets have a chance to remain and stars definitely do.
As for 'all' I should have said most but it seemed a bit pedantic even for me. ALMOST all would be more accurate. However I am not aware of any system that with an OBSERVED supernova that had much if anything remaining after. Both the Crab and 1987a systems are pretty much empty in the zone where planets would form. The case Oliver posted MAY have been a type IIa supernova but no one was certain of it.>>

Oliver does have many different ideas that I do not agree with. But he is not the first person to propose a supernova origin to our solar system. I happen to think it has more merit than any other idea.
Here are two reason I say this, one the heavier elements are neared the the sun or the original neutron star. This is exactly like all explosions from the center out.
Secondly, isn't a bit strange that ALL the planets orbit the sun on nearly the same plane and in the same direction?
This also indicates a common source not some random picking up of heavy elements from some distant supernovae.

He is the only person pushing it as OUR Sun being the source. I am FULLY aware that a supernova was involved in the Solar Systems beginning. I have so said on this very thread. If you look carefully at Olivers stuff his first attempt to make that idea public was at a convention and he was expecting to give a talk. Someone ELSE gave a talk on a supernova being involved in the initiation of our Solar System. That person didn't claim the SUN was what went bang which is likely the reason he gave a talk and Oliver did not.>>

This is already understood. Light elements cannot remain in the inner solar system after the Sun lights up. Heavy elements ARE in the outer Solar System.
Except it ignores the fact that ALL the elements from the supernova are almost entirely blown out of any system.
No. And a magic supernova would have to be REALLY magic to have anything to do with that. The formation of a disc is inherent as a gas cloud collapses.>>

We can see star forming nebulae with young massive stars in them. Those stars are too massive to last long. The largest, which are the ones that will create the most metals, are going to supernova before the nebula is scattered. We can see this in the Carina Nebula which is still quite dense and will soon be blasted by the supernova of Eta Carinae. That Sun could go at any time in the next million years or even the next day, though thousands of years seems more likely a million years seems rather long for such a massive star.>>

You are agreeing with the most idiotic of them. The Sun could not have ever had a pulsar in it. The mass is wrong and a pulsar simply isn't going to shed mass or have neutron decay. The surface gravity is too high for the former and the core pressure that created the neutronium in the first place is going to keep it that way.

That has absolutely nothing to with a the Sun not having been a supernova. Or rather if the Sun was the supernova then where did the angular momentum come from in the solar system. It was the rotation of the cloud that caused it to form a disc as it collapsed. Obviously that concept escaped you.
The Sun and planets came from the same cloud. So they have same angle of rotation.

Neutrons decay in a nuclei after being stable for millions or billions of years. So what causes the neutron to suddenly decay? It cannot be pressure because the pressure is the same throughout this period of time according to the Standard Model.

The lower output of energy from our sun in earlier times, there was the remnants of neutron star early in our sun's life.

I really do not understand your statement. Let me simply state it this way a very LARGE star goes supernova leaving behind a neutron star along with asteroid size chunks of heavy elements orbiting it. The neutrons on the surface of this neutron star, now only slightly larger than our sun, decay into hydrogen. The asteroid size chunks of heavy elements form the earth and the other planets over millions of years.
During these millions of years the hydrogen builds up on surface into a large enough quantity and under the intense gravitational pressure of the core neutron star it starts fusing again.
