📣 New title image 🖼️
The diagram shows results from a numerical relativistic computer simulation of merging neutron stars.
The new simulation takes into account muons and their reactions to get a physically more complete picture of what happens in these extreme cosmic events.
Researchers at @unipotsdam, at Universidade Federal do ABC in Brazil, and at @mpi_grav have recently published their results: https://arxiv.org/abs/2604.14225.
The diagram from that manuscript shows the muon fraction and its deviation from equilibrium at different times after merger.
The most important finding: Unlike reported in the literature so far, taking into account muons and their reactions only plays a minor role – at least in the context of calculating the synthesis of elements in neutron star mergers and their optical counterparts observable with telescopes.

"Researchers in China say that they are the first to use cosmic-ray muography to monitor the region surrounding a tunnel. Described as a lightweight, robust and affordable scintillator setup, the technology was developed by Kim Siang Khaw at Shanghai Jiao Tong University and colleagues. They hope that their approach could provide a reliable and non-invasive method for the real-time monitoring of subterranean infrastructure."

Forged in FreeCAD: CERN CMS Detector Cable Clamps
In case it passed you by, over on our mastodon account and on the X platform we have run the hashtag #FreeCADFriday for a long time. It's a straightforward "show everyone what you are up to with FreeCAD" type affair and every week so many amazing projects show up as responses.

Let me share one of the pictures from todays #physics data analyis work.
It is a Dalitz plot visualizing the fractions of the signals in three photodiodes registering scintillation light excited by #cosmicrays #muons in a big Bismuth-Germanium-Oxide #BGO crystal. The colors represent different data selection criteria.

🚨 Final results from a long-running experiment at Fermilab show muons—tiny particles—are still acting weird, challenging our understanding of the universe. 🌌 Scientists are racing to reconcile these findings with the Standard Model using supercomputers. More to come! 🔬

Particles hint at fifth fundamental force
https://www.futuretimeline.net/blog/2023/08/26-particles-hint-at-fifth-fundamental-force.htm #muon #muons #physics #fermilab
-
Scientists at Fermilab are nearing the discovery of a fifth force of nature, a new type of interaction that could explain some of the mysteries of the universe. The fifth force could be related to the behaviour of muons, tiny particles similar to electrons. Muons wobble in a magnetic field in a way that does not match the predictions of the standard particle physics model, suggesting that something else is influencing them.
-
Scientists working at Fermilab have moved forward in understanding the strangeness of muons in a way that might contradict the Standard Model. I don't understand more than a tenth of this stuff, but it does seem very exciting!

Scientists at #Fermilab close in on fifth force of nature
Scientists near Chicago say they may be getting closer to discovering the existence of a new force of nature.
They have found more evidence that sub-atomic particles, called #muons, are not behaving in the way predicted by the current theory of sub-atomic #physics.
Scientists believe that an unknown force could be acting on the muons.

Maybe best to skip the media interpretations and go straight to the source on this.

They have found more evidence that sub-atomic #particles, called #muons, are not behaving in the way predicted by the current theory of sub-atomic #physics.
Scientists believe that an unknown force could be acting on the muons.
But extraordinary results require extraordinary evidence, so physics beyond the standard model has not been conclusively demonstrated quite yet.

According to the authors of the paper published in iScience [4]: "With further improvements in stability of local clocks used for timing, it is anticipated that MuWNS can be adapted to improve autonomous mobile robot navigation and positioning as well as other underground and underwater practical applications."
In what other ways do you think this technology can be used? Deep-sea mission navigation perhaps?
-
Muons have been used previously to image archeological structures, search for hidden Mayan ruins, and detect hidden corridors and chambers of the Great Pyramid of Giza [3].
Recently, the first navigation with wireless muometric navigation system (MuWNS) in indoor and underground environments was successfully tested [4] showing accuracy exceeding the GPS single-point positioning.
-
You know GPS but have you heard of muPS (Muometric Positioning System)?
The muometric positioning or navigation system (muPS/μPS/muNS) is a novel positioning/navigation system that utilizes the ubiquitous and highly-penetratve cosmic-ray muons [1][2].
This technique does not require active signal generation [1][2] and is usable in environments where GPS/GNSS signals cannot reach such as underwater and underground.

Superfast, #subatomic-sized #particles called #muons have been used to wirelessly #navigate underground in a reportedly world first. By using muon-detecting ground stations synchronized with an underground muon-detecting receiver.
