"Measuring the Spectrum of High-Energy Cosmic-Ray Electrons" -
Physics as a community has often acted like one large recycling program. I was looking for sources for a paper I am co-authoring when I found a report from 1969 about a mobile #CosmicRay station. I read it and spotted the B&W photo below, showing the specialized curved lead bricks.
Those same bricks are now used in the #HALO experiment @SNOLAB, which recycled the lead from a cosmic ray station in Deep River, ON, Canada … the same site that made this mobile cosmic ray station!

#fallout #fallouttv #retro #nostalgic
I have a #serial #terminal like the ones used in the #fallout #television #show. One of the plastic #monitor tube mounting posts is broken and it did not turn on but might just be a fuse. Been sitting in the attic for a long time. I salvaged it from the university of #minnesota #CosmicRay lab when they shut it down 35 years ago. It was used to #bootstrap a #PDP-11 #computer by typing in several lines of assembly to bring up the main #OperatingSystem. I'll see if I can get it working again or may be repurpose/retrofit it as a modern computer monitor. They offered me the PDP-11 at the time also but it was too big for me to retain.

A Ray From #Space Hit #Earth with Such Incredible Power That Scientists Named It After a God
The source of the #Amaterasu particle, named after the Japanese sun goddess, is a "big mystery." It’s the second-highest-energy #cosmicray ever recorded, at 240 exa-electron volts (Eev), second only to the aptly-named "Oh-My-God particle" discovered in 1991, which clocked in at 320Eev. Researchers describe the energy as equivalent to dropping a brick on your toe from waist height. https://www.vice.com/en/article/v7bqj3/amaterasu-cosmic-ray-hit-earth -
Meet “#Amaterasu”: #Astronomers detect highest energy #cosmicray since 1991
The #Telescope Array in Utah's West Desert picked up a rare particle with 244 EeV energy. It's the most energetic cosmic ray detected since 1991, when astronomers detected the so-called "Oh-My-God' particle, with energies of an even more impressive 320 EeV. Astronomers have dubbed this latest event the "Amaterasu" particle, after the Shinto sun goddess said to have created Japan. https://arstechnica.com/science/2023/11/meet-amaterasu-astronomers-detect-highest-energy-cosmic-ray-since-1991/ -

The most powerful cosmic ray since the Oh-My-God particle puzzles scientists
Scientists spot a particle of intense energy, but explaining where it came from might require some new physics.

Discovery of the Amaterasu 240 EeV cosmic ray particle, named after the goddess of the sun in Japanese mythology, by the Telescope Array observatory in Utah. This mysterious event appears to have emerged from the Local Void. Intriguing!

Correlations between changes in #CosmicRay intensity ☢️ and #earthquakes are not apparent in location-specific analyses. They only appear when seismic activity is taken into account on a #global 🌏 scale. https://phys.org/news/2023-06-intriguing-earthquakes-cosmic.html

This thing is absolutely amazing 😍🤩 Using #cosmicray data from two different locations on earth, scientists and hobby musicians created an amazing interactive display. #science and #music are often considered similar in many senses. But now one can clearly see the connection when listening to cosmic jams. 🤩

How do astronomers guess the maximum energy that can be reached by a (potential) #CosmicRay accelerator, if they can just know the basic macroscopic properties of a potential source?

#CMSPaper 1205: Some particle collisions look like they make particles but can also be seen as relatively incohesive blobs of #particles like #quarks and #gluons. These effective particles are referred to as #pomerons.
This paper is the first time pomerons are measured in lead-proton collisions! These results show the theory calculations of these are pretty bad, so the data will also help in modeling #cosmicray air showers.
