That discovery indicates the presence of a super cosmic ray accelerator inside the bubble, which continuously accelerates high-energy cosmic ray particles with energies of up to 20 PeV and injects them into interstellar space. These high-energy cosmic rays collide with interstellar gas and produce g...
THE origin and propagation of cosmic rays have been intriguing physicists ever since their discovery in 1912. The main obstacle to identifying the sources of charged particles is the galactic magnetic field. Since the Larmor radii for protons in a typical interstellar field of 3 µgauss are belo...

AnAuthor Correctionto this article was published on 06 April 2021 This article has beenupdated Abstract Cosmic rays with energies up to a few PeV are known to be accelerated within the Milky Way1,2. Traditionally, it has been presumed that supernova remnants were the main source of these ver...
Researchers of the Large High Altitude Air Shower Observatory (LHAASO) discuss on the data gained from the detectors in Daocheng County, southwest China's Sichuan Province, April 28, 2019. An observatory for detecting cosmic rays in southwest China's Sichuan Province recently began scientific ...
cosmic-rays; re-acceleration; supernova remnants; stellar wind1. Introduction Cosmic Ray (CR) particles are mainly protons (90%) and nuclei with a spectrum that extends over 15 orders of magnitude in energy (𝐸=[1010÷1020]E=[1010÷1020] eV). Such a large energy range can be explained...

Molecule production composed of H, C, N is known to occur in Titan's atmosphere with energy input from the magnetosphere, solar UV, and deep-penetrating irradiation from galactic cosmic rays (GCR). Space radiation effects by GCR irradiation of Titan's surface and lakes can lead to the ...
This multiwavelength image of the Cloverleaf ORC (odd radio circle) combines visible light observations from the DESI (Dark Energy Spectroscopic Instrument) Legacy Survey in white and yellow, X-rays from XMM-Newton in blue, and radio from ASKAP (the Australian Square Kilometer Array Pathfinder) in...
(see Supplementary Fig.1). They all stopped on March 13th 2020 after an electricity cut due to a storm. Charpak was restarted on March 18th at a reduced gas flow, and definitely stopped on April 6th following the COVID-19 pandemic. All in all, Degennes and Joliot accumulated about 140...
