Amaterasu and GRB221009A: A Comparison of Cosmic Rays and Gamma Ray Bursts

[paulalex7000]

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.
