AI Thread Summary
Amaterasu is identified as an extremely high-energy cosmic ray, not a gamma ray or gamma-ray burst, and its origin remains uncertain, potentially being a proton. In contrast, GRB221009A is a gamma-ray burst resulting from a star's collapse, producing about 18 tera-electron volts of energy and detected over several minutes with thousands of high-energy photons. The energy of Amaterasu, cited as 244 exa-electron volts, is likely misinterpreted, as cosmic rays are not directly comparable to gamma-ray bursts. The mechanisms behind ultra-high energy cosmic rays are not well understood, and their detection is complicated by statistical fluctuations and magnetic field influences. Overall, Amaterasu and GRB221009A represent fundamentally different cosmic phenomena.

TL;DR Summary
Can this "Amaterasu" particle and GRB221009A be compared against each other? The former is always noted as a gamma ray (singular), nowhere have I read it being referred to as a gammy-ray burst, however.
Can this Amaterasu particle and GRB221009A be compared against each other? The former is always noted as a gamma ray (singular), nowhere have I read it being referred to as a gammy-ray burst, however. Does this mean scientists have detected this one lone gamma ray and only one?

[Edit/Update: I just reread an article and noticed it said "cosmic" ray, not "gamma" ray. So I guess this nullifies my questions posted?]

They say that Amaterasu gave off energy equaling 244 exa-electron volts. Doesn't that beat out GRB221009A, which was about 18 tera-electron volts? Please correct my misunderstood interpretation.

I'm not sure what the total energy of GRB221009A ended up being, as it was a gamma ray burst lasting several minutes at its peak with over 5,000 high energy photons detected. So it could go either way I suppose.

The Amaterasu cosmic ray was not a gamma ray burst or even a gamma ray at all. It was an extremely high energy single particle of origin unknown. Maybe a proton.

The GRB221009 event was an extremely energetic collapse of a star.

Using cutsie-poo names is unnecessary, and does not add to one's credibility. Science popularizers and university press offices might not know any better, but we should. We can just call them ultra-high energy cosmic rays.

Some facts:
1. It is known that these are extremely energetic. Are the energy measurements accurate at these energies? Hard to tell. You don't have an independent calibration, and you are plagued by statistical fluctuations.
2. Primary cosmic rays are not photons/gamma rays. They are protons or nuclei.
3. Charged particles bend in magnetic fields: the directiopn where the particle appears to come from is not the direction of the source.
4. The acceleration process for ultra-high energy cosmic rays is poorly understood. It is likely electromagnetic. Thus, it may be easier to accelerate these particles if they are fully-stripped nuclei, such as iron.None of these suggest a relationship with any GRB.

I guess that's on me... I'm not part of any academia, just a layperson who has an interest in cosmology, but from a civilian viewpoint.

No fault on you. We're just quite... thorough... around these parts. :wink:

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
