I had the pleasure to be interviewed by Alexandre Morales for France Culture, to talk about the discovery of Quipu, one of the largest known structure of the Universe. It will air tomorrow morning at 6:52.

Here is the press release by the authors of the discovery at MPI Garching https://www.mpg.de/24197951/largest-superstructure-in-the-nearby-universe

Unveiling the largest structures in the nearby Universe - discovery of the Quipu superstructure: https://arxiv.org/abs/2501.19236 -> Largest #superstructure in the nearby #universe discovered: https://www.mpg.de/24197951/largest-superstructure-in-the-nearby-universe - data from the former #ROSAT X-ray satellite have revealed a network of 68 galaxy clusters in the nearby universe, stretching over 1.4 billion light-years.

I just love this institute so much...

No just because of the best memes, but well... The memes are the best!

Superposed on an optical picture of a group of #galaxies is an image taken in #Xray light.

The X-ray picture, by #ROSAT, shows confined #hotgas highlighted in false red color, and provides clear evidence that the #gravity exerted in groups and clusters of galaxies exceeds all the individual component galaxies combined.

The extra gravity is attributed to #darkmatter.

Here is a special Nature cover for the International #ObserveTheMoon Night!

The first soft X-ray image of the Moon, courtesy of reflected solar X-rays, captured by the ROSAT Satellite. The dark side of the Moon shadows a diffuse cosmic X-ray background.
