#ixpe — Public Fediverse posts

Fu la supernova più brillante mai documentata nella storia, un’esplosione stellare di potenza estrema che trasformò temporaneamente l’aspetto del cielo e lasciò tracce durature sia nella memoria umana sia nella materia dello spazio.

La più lunga osservazione mai effettuata da IXPE risolve il mistero dei getti virali dei buchi neri

#chandra #IXPE @astronomia

Un team internazionale di astronomi che utilizza IXPE (Imaging X-ray Polarimetry Explorer) della NASA ha identificato l’origine dei raggi X nel getto di un buco nero supermassiccio, rispondendo a una domanda rimasta irrisolta fin dagli albori dell’astronomia a raggi X.

NASA’s IXPE Reveals X-ray-Generating Particles in Black Hole Jets

The blazar BL Lacertae,with its jets oriented toward Earth, provided scientists with a unique opportunity to answer a longstanding question: how are X-rays generated in extreme environments like this?

I'm writing a short talk about recent #astrophysics results from #IXPE, the #NASA Imaging X-ray Polarimetry Explorer, and needed a picture of the telescope for the title slide. I stumbled on 3D files that NASA has published, and rather clumsily tried to print them with my 3D printer.

The result is flimsy, glued together, and entirely the wrong colours, but it's *mine*:

🤯 Soft X-ray polarization in the black hole X-ray binary Cygnus X-1 can be explained by returning radiation, i.e. radiation from the disk returning back due to GR effects & reflected off the disk!

🛰️🔭 Le 23 mars, le télescope #IXPE de la NASA a cessé de transmettre des données de télémétrie valides.

Le 26 mars, IXPE est passé en “safe mode” (mode sûr). IXPE transmet à nouveau des données de télémétrie valides mais les opérations scientifiques n’ont pas encore repris.

NASA’s #IXPE (Imaging X-ray Polarimetry Explorer) stopped transmitting valid telemetry data on March 23, but by March 26 that problem was solved: https://science.nasa.gov/general/ixpe-operations-update/ - science operations should resume shortly.

NASAのIXPEが一時的なデータ送信の問題に直面しましたが、アビオニクスリセットにより問題が解決され、再び正常なテレメトリデータを送信していることが確認されました。IXPEは2021年に打ち上げられ、

Beethoven wasn’t the only one with dramatic flair 200 years ago—Sagittarius A*, the Milky Way’s supermassive black hole, may have also composed an intense flare as it consumed nearby material.

The aftermath of a supernova has been mapped and measured in a new way, using our Imaging X-ray Polarimetry Explorer (IXPE).
