One of the key problems in the theory of the origin of cosmic rays, which consist of high-energy protons and atomic nuclei, is their acceleration mechanism. The issue was addressed by Vitaly Ginzburg and Sergei Syrovatsky in the 1960s when they suggested that CRs are generated during superno...
We propose a mechanism to explain the low-frequency QPOs observed in X-ray binary systems and AGNs. To achieve this, we perturbed stable accretion disks ar
21. Our experiments also produce plasma jets that have magnetic Reynolds numbers large enough for the magnetic field to be ‘frozen into’ the plasma flow. Consequently, the plasma in the jet must follow the field topology and its evolution, which is locally kinked but globally ‘collimated’ a...
The scientific study of celestial occurrences and objects, such as stars, planets, galaxies, and cosmic radiation, that take place outside of the Earth's atmosphere is known as astronomy. It entails utilizing telescopes and other tools to observe and examine these objects' characteristics and ...
and as evident from all his own comics aboutexoplanets, it is now clear that many of the stars in a galaxy also have planets orbiting them. Thus the number of stars and planets in that small circle is much more mind-bogglingly large, than the number of galaxies, and thus the reassurance...
These similarities provide rigorous justification of the relevance of the plasma jet to the Crab nebula jet, preserving the facts that the energy flux is predominantly carried by the Poynting flux close to the pulsar pole and by the particles close to the termination shock. The consistency between...

“Basically, the star would be too massive for the jet to pierce through,” Gottlieb said. “So the jet will never make it out of the star, and that’s why it fails to produce a GRB. However, in these stars, the dying jet transfers all its energy to the cocoon, which is the onl...
