QPE

This is a real X-ray image (speed up 4000x), with a real X-ray light curve,
of the nucleus of the galaxy GSN 069, taken with the XMM-Newton space observatory on January 16/17 2019.

Never before such recurrent, intense, sharp eruptions of X-rays had been observed in the nucleus of a galaxy.

Quasi-periodic Eruptions had been discovered.


➜ Check out the Nature blog entry written by Giovanni Miniutti, the QPE discoverer: undefined


➜ Read the story of the QPEs discovery, and the little we know and understand so far.


A few scientific talks about QPEs given by Giovanni or myself:

💻 “X-ray quasi-periodic eruptions (QPEs)” — presented by Giovanni Miniutti at the “X-ray Astronomy 2019” conference, held in Bologna (Italy) in September 2019.

💻 “Nine hour X-ray Quasi-Periodic Eruptions (QPEs) from the nucleus of the Galaxy GSN 069” — presented by Giovanni Miniutti at the “XMM-Newton 20th anniversary” event held at the European Space Astronomy Centre (ESAC, Spain) in December 2019. Here you can find the video of the talk.

💻 “The discovery of X-ray quasi-periodic eruptions” (video) — seminar given by myself at the Centro de Astrobiologia in July 2020.
