Rentgenové záření z gama záblesku GRB221009A, jak ho zachytila observatoř Swift.

Tento gama záblesk je znám jako BOAT, tedy nejjasnější všch dob, bylo jej možné pozorovat několik týdnů.

¿Cómo sobrevivió un fotón de 300 TeV a 2.000 millones de años luz?
Un fotón de unos 300 TeV recorrió más de 2.000 millones de años luz y llegó a la Tierra pese a que la física esperaba que fuera absorbido mucho antes.

Limiting on ALP-photon Coupling through GRB221009A
This study investigates the constraints on ALPs parameters through the photon-ALP oscillation model, based on the high-energy photon propagation characteristics of the gamma-ray burst GRB 221009A. We briefly describe the Primakoff process and use it to derive the oscillation probability. Numerical simulations incorporate the GMF, IGMF, and EBL, utilizing the open-source code gammaALPs to simulate photon propagation from the source to Earth. By employing the chi2 statistical method and segmented spectral fitting of low-energy and high-energy observational data from HXMT-GECAM, the dependence of photon survival probability on ALP mass (ma) and coupling strength (ga) is analyzed. Results show that for the ALP mass range 10^-7 < ma < 10^2 neV, the upper limit on the coupling strength is ga < 0.27 * 10^-11 GeV^-1, improving constraints by one order of magnitude compared to the CAST experiment (6.6 * 10^-11 GeV^-1). Notably, high-energy data exhibit significantly stronger constraining power. This work provides a novel theoretical framework and observational basis for indirectly probing ALPs through extreme astrophysical phenomena.

Here's a mosaic of stills from the gif.

Each circle is from a band of dust at a given distance - a few hundred to 20000 parsecs.

There is a great paper about the rings here:
arxiv.org/pdf/2302.02383
4x4 grid of images from successive days of Swift observatory observations of GRB221009A. Each shows a bright centre, with a number of concentric, brighter rings. We are seeing X-rays emitted by dust in our galaxy as the gamma-ray burst hit the dust. The images are essentially the same, just each day a little larger, as there has been time for the light to travel a longer path to us. A moon-dog of a gamma-ray burst if you like.
