How Do Quasars Demonstrate That The Universe Evolves With Time | Porphyrion Jets

This will blow your mind, In this blog post we discussed how do quasars demonstrate that the universe evolves with time. But what is Quasar? Well stay with me, we have talked about this cosmic monster further in the post.

Now imagine you are standing in a remote corner of the universe. Everything is quiet, there is no movement, and suddenly, a dark, mysterious spot of light appears in front of you—a black hole! But this is no ordinary black hole. It is giving birth to one of the most powerful jets in the universe, which extends up to 23 million light-years as if this black hole is showing its power to the entire universe. This sight is like fire coming out of a dragon’s mouth, which can engulf countless galaxies in one stroke.

Yes, a team of international astronomers has seen a black hole releasing record-breaking jets in the remote depths of the universe. You can guess how far these jets extend in the universe from the fact that our galaxy, the Milky Way, can be fitted 140 times from one end of these jets to the other.

Porphyrion Jets, The New Record Holder

The journal Nature recently published the discovery. Researchers have coined the name Porphyrion, a demon in Greek mythology who fought for the power of the universe against the gods. These are the biggest jets that have ever been identified, and their size outstrips the previous record holder ‘Alcyoneus’. The same astronomers found Alcyoneus in 2022. It is located in the Lynx constellation and is 3.5 billion years away from our Earth. The jets of Alcyoneus are so huge that up to 100 Milky Way galaxies could fit into it from one side to the other.

At the same time, the jet system closest to Earth among these two is that of a galaxy called Centaurus A. This galaxy is 11 million to 13 million light years away from us and can fit about 10 Milky Way galaxies from one end to the other.

Well, coming back to these record-breaking jets seen 7.5 billion light years away, scientists believe that this jet system dates back to when our universe was 6.3 billion years old, or less than half its current age of 13.8 billion years. These massive outflows—whose total power output is equivalent to trillions of suns—emerge from above and below a supermassive black hole at the center of a distant galaxy.

According To Current Theories Of Galactic Evolution Quasars Occur

But the question is, how are these jets formed? And how much impact can they have on our universe?

With a supermassive black hole at its center, every big galaxy, in turn, houses an enormous amount of matter. Most of the time, though, black holes just sit there, minding their own business, until matter starts falling toward them, at which point they come to life and shoot out strong energy through jets by spinning that matter around them in a disk. The energy from these jets is so strong that, besides their very own galaxy, they can influence nearby galaxies and even groups of stars.

Porphyrion was discovered in data from Europe’s LOFAR (Low-Frequency Array) radio telescope. Radio waves are the best way to look for giant black hole jets. When matter falls into a black hole, it is ejected at such a high speed that these radio waves are produced, which can be captured by our instruments.

Martijn Oei and his colleagues from Caltech and Leiden University in the Netherlands were the lead authors of this discovery. The LOFAR survey discovered more than 11,000 jets larger than one megaparsec, or 3,260,000 light years. Before this survey, scientists knew of only a few hundred jets.

The origin of the Porphyrion jets has now been determined, thanks to data from the Giant Metrewave Radio Telescope in India and also from a project called the Dark Energy Spectroscopic Instrument, which works at Kitt Peak National Observatory in Arizona. Confirming observations show that the galaxy that these record-breaking jets are coming from is 10 times heavier than the Milky Way. I want to remind you again that this discovery happened when the universe was only 6.3 billion years old-around half its age.

Black Hole Relativistic Jet Formula And Connection With Old Universe

These giant jets not only extend out of their galaxy into the cosmic void — empty space between galaxies and star clusters—but are now some of the largest structures in the entire universe. If these jets are common, it is important to understand how they might affect the universe’s structure.

Astronomers have come to understand in recent decades that the evolution of galaxies and their central black holes is deeply intertwined. Even when jets from black holes escape the galaxies’ boundaries, their influence does not end there. They can not only inhibit the birth of stars in their host galaxies but also heat and magnetize material in the other galaxies.

This process is extremely complex and gives us insight into how black hole jets can organize matter on a large scale in the universe. It was previously thought that this process had been going on since the Big Bang, but now, these jets may be the main driver of this entire sequence.

The extremely long length of Porphyrion has raised several questions among astronomers. Until now, all known systems of megaparsec-scale giant jets were found near Earth in the latter half of the universe’s history of 13.8 billion years. Astronomers have spotted most of them in old elliptical galaxies that are “red and dead”.

How Much Energy Do Quasars Give Off

Now, while black holes can put a lot of energy into their jets – as much energy as the stars in more than 100 galaxies – these jets take hundreds of millions of years to expand to record-breaking lengths. Moreover, younger, star-forming galaxies were thought to be too unstable to maintain jets for a long time.

But Porphyrion exists, and at a very early time in our universe’s history, when the universe was much more active and compact than it is today. The ever-expanding universe has expanded to reach a width of 140 times the length of the Milky Way, less than half the universe’s age, an even more impressive distance when the universe was much younger.

Porphyrion’s long reach extends not just beyond its host galaxy but two-thirds of the way into the cosmic void, the space between galaxies and superclusters of galaxies. That means its reach is truly cosmological, on the scale of the largest structures in the universe.

It’s only the largest of the nearly 11,000 giant jet systems discovered (there are tens of thousands more smaller jet systems). Now, the LOFAR telescope will gather more data to further investigate, which could lead to thousands more such jet systems. Scientists are now trying to understand these giant structures using machine learning to see if they play a bigger role in the universe’s evolution than previously thought.

“Until now, these enormous jet systems have looked like a new thing in the universe,” said Ooi. “If these distant jets can compete with the size of the cosmic web, then the activities of these black holes must have affected the universe at some point in its past, in every single corner of the universe.”

Conclusion

So now it is natural to ask the question, to what extent can jets like Porphyrion affect the evolution and structure of our universe? Can their effect be felt even on the largest scale of the entire universe? As we make more discoveries, we will be able to understand the effect of these mysterious and powerful black holes even more deeply.

These black holes exist not only in the universe but are the biggest players in shaping our galaxies, stars, and even our existence. Jets like Porphyrion have proved that we still have a lot to know about our universe.

What do you think? Can these black holes with even bigger jets exist in our universe or not?

Recently, a published study suggests that the Betelgeuse star may be a binary star.
