Microquasars in our Milky Way galaxy have emerged as the most extreme particle engines, accelerating cosmic rays to unprecedented energies. These compact objects, found in binary star systems, rival ...

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...

LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed ...

(Nanowerk News) Our home planet is bombarded with particles from outer space all the time. And while we are mostly familiar with the rocky meteorites originating from within our solar system that ...

"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic rays are produced in the jets of microquasars." When you purchase through ...

Modern astronomy has clung to the belief that the relativistic outflows or jets, responsible for the existence of electromagnetic radiation of particularly high energies, are located in the nuclei of ...

understanding of the enigmatic stellar pairs known as microquasars. "This once-a-day series of exquisitely-detailed images is the best look anyone Michael Rupen, Greg Taylor and Craig Walker, all of ...

Some of the most energetic cosmic rays in the galaxy may come from a surprisingly small source. If Max Planck Institute for Astrophysics researcher Laura Olivera-Nieto and her colleagues are right, ...

1. Microquasars: summary and outlook -- 2. X-ray emission from black-hole binaries -- 3. State and transitions in black-hole binaries -- Radio emission and jets from microquasars -- 5. 'Disc-jet' ...

Some of the brightest objects in the Universe are supermassive black holes at the hearts of galaxies—black holes with masses millions or billions of times greater than the Sun. As matter falls toward ...

The brightest objects in the universe are called quasars, and now astronomers have found the first miniature version of a quasar beyond the Milky Way. Quasars are supermassive black holes up to ...
