Unique among its peers is the top quark ­– a fascinating particle that the scientific community has been studying in detail since the 90s. Its large mass makes it the only quark to decay before forming bound states (a process known as hadronisation) and gives it the strongest coupling to the Higg...

De nouvelles perspectives sur le mécanisme de la fission nucléaire !

À la tête d’une collaboration internationale 🌐, les physiciens nucléaires de l'installation ALTO (laboratoire IJCLab - Université Paris-Saclay / CNRS) ont démontré comment le spin de deux fragments, résultant de la fission d'un noyau atomique, était généré.

Since the discovery of the Higgs boson in 2012, scientists in the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) have been hard at work characterising its properties and hunting down the diverse ways in which this ephemeral particle can decay. From the copious but experimentally cha...

When a massive star collapses under its own gravity, it forms a black hole that is so heavy that it captures everything that passes its event horizon. Not even light can escape. At the event horizon, time replaces space and points only forward. The flow of time carries everything towards a singularity furthest inside the black hole, where density is infinite and time ends (see figure).

Roger Penrose – awarded the 2020 Nobel Prize in Physics – invented ingenious mathematical methods to explore Albert Einstein’s general theory of relativity. He showed that the theory leads to the formation of black holes, those monsters in time and space that capture everything that enters them.

Not even Albert Einstein, the father of general relativity, thought that black holes could actually exist. However, ten years after Einstein’s death, the British theorist Roger Penrose demonstrated that black holes can form and described their properties. At their heart, black holes hide a singularity, a boundary at which all the known laws of nature break down.

To prove that black hole formation is a stable process, Penrose needed to expand the methods used to study the theory of relativity – tackling the theory’s problems with new mathematical concepts. Penrose’s ground-breaking article was published in January 1965 and is still regarded as the most important contribution to the general theory of relativity since Einstein.

The 2020 Nobel Prize in Physics has been awarded with one half to Roger Penrose “for the discovery that black hole formation is a robust prediction of the general theory of relativity” and the other half jointly to Reinhard Genzel and Andrea Ghez “for the discovery of a supermassive compact object at the centre of our galaxy.”

Reinhard Genzel and Andrea Ghez – awarded the 2020 Nobel Prize in Physics – discovered that an invisible and extremely heavy object governs the orbits of stars at the centre of our galaxy.

Reinhard Genzel and Andrea Ghez each lead a group of astronomers that, since the early 1990s, has focused on a region called Sagittarius A* at the centre of our galaxy. The orbits of the brightest stars closest to the middle of the Milky Way have been mapped with increasing precision. The measurements of these two groups agree, with both finding an extremely heavy, invisible object that pulls on the jumble of stars, causing them to rush around at dizzying speeds. Around four million solar masses are packed together in a region no larger than our solar system.

Using the world’s largest telescopes, Genzel and Ghez developed methods to see through the huge clouds of interstellar gas and dust to the centre of the Milky Way. Stretching the limits of technology, they refined new techniques to compensate for distortions caused by the Earth’s atmosphere, building unique instruments and committing themselves to long-term research. Their pioneering work has given us the most convincing evidence yet of a supermassive black hole at the centre of the Milky Way.
