  3. Three weeks ago, the scientific journal Nature @nature reported the discovery of the most energetic #neutrino ever observed. Its energy is 16,000 times greater than the strongest particle collisions created by the Large Hadron Collider and corresponds to 30 times the energy needed to press a computer key.

    The neutrino was discovered in an underwater observatory in the Mediterranean, one of three neutrino detectors in water - two in the Mediterranean and one at Lake Baikal. At the geographic South Pole, there is the #IceCube neutrino detector under the ice. Other detectors exist underground in China, Italy, and Japan.

    All these #detectors are not located on the Earth's surface because the Earth itself acts like a #telescope for neutrinos. Neutrinos are extremely light, electrically neutral particles that interact very weakly with matter and pass through the Earth. When they collide with atomic nuclei, charged particles are produced that move faster than light in water or ice, emitting blue light that is captured.

    Water and ice are ideal media for detecting neutrinos because they provide large volumes to detect these particles while shielding against cosmic radiation and other disturbances. IceCube even utilizes 1 cubic kilometer of ice.

    Neutrinos are the second most abundant particles in the universe, after photons, but are difficult to study because they interact so little with matter. Interestingly, dark matter and dark energy, which make up 95% of the universe, also interact very weakly with normal matter, while the remaining 5% consists of elements like #hydrogen and #helium, of which only 0.5% is visible matter (such as #stars).

  4. "On Wednesday, a team of researchers announced that they got extremely lucky. The team is building a detector on the floor of the Mediterranean Sea that can identify those rare occasions when a neutrino happens to interact with the seawater nearby. And while the detector was only 10 percent of the size it will be on completion, it managed to pick up the most energetic neutrino ever detected."

  5. [The “JENI” of #JUICE 🤩] There are #detectors that capture the invisible: #atoms emitted by energetic ions trapped in the Earth's #magnetosphere, in this case. Then comes this image of the hot #plasma surrounding our #Earth ...

    This image was captured by NASA's #JENI (Jovian Energetic Neutrals and Ions) instrument, to which IRAP contributed, as the #JUICE probe moved away from Earth, last August. This is the clearest image yet of the #Earth's #radiation belts

  7. #introduction #reintroduction for all the new folks around here I'm hearing about.

    I'm an experimental particle physicist working on the CMS experiment. My primary foci at the moment are top quark physics through the lens of EFT (effective field theory), and FPGA programming for the purpose of development, testing, and operations of detector electronics.

    Before CMS, I worked on the SuperCDMS experiment looking for dark matter. I developed the level 1 trigger for the upcoming SuperCDMS run at SNOLAB, and also developed the simulation of the transition edge sensors and charge sensors that are part of the SuperCDMS detectors.

    Before SuperCDMS, I worked on the CDF (Collider Detector at Fermilab) experiment. There, I studied the top quark and the Higgs boson. I performed the world's first-ever published search for ttH production, and measured the forward-backward asymmetry in top-antitop production at the Tevatron.

  8. Astronom*innen haben anhand von neuen Beobachtungen mit dem Atacama Large Millimeter/submillimeter Array (ALMA) komplizierte Details der Sternentstehungsregion 30 Doradus, sichtbar gemacht, die auch unter dem Namen Tarantelnebel bekannt ist. Auf einem hochauflösenden Bild, das heute von der Europäischen Südsternwarte (ESO) veröffentlicht wurde und ALMA-Daten enthält, sehen wir den Nebel in einem neuen Licht: Hauchdünne Gaswolken geben Aufschluss darüber, wie massereiche Sterne diese Region beeinflussen.
