Observations of the shock between this pair of clusters showed that the radio emission was connected to the galaxy's jet, so clearly the electrons must have been initially
accelerated by the black hole and then reaccelerated by the shock waves.
Not exact matches
Over time, it should detect tens or hundreds of cosmic rays from individual AGNs and their range of energies should clarify exactly how they were
accelerated — a process thought to be controlled
by magnetic fields around the colossal
black holes.
In the Universe, cosmic ray particles are
accelerated by galaxy clusters, supernovae, binary stars, pulsars and certain types of supermassive
black holes.
Now, a new theoretical model reveals that they all could be shot out into space after cosmic rays are
accelerated by powerful jets from supermassive
black holes.
To address this issue, the researchers constructed the first
black hole simulation code
accelerated by graphical processing units (GPUs).
According to the most prevalent theory, the
black hole and the gas disk are surrounded
by a strong magnetic field in which particles such as electrons are
accelerated to almost the speed of light.
Sagittarius A *'s immense gravity is
accelerating the cloud dramatically: in 2004, the cloud was hurtling toward the
black hole at 1200 kilometers per second;
by 2011, the speed had nearly doubled, reaching 2350 kilometers per second.
Ray Jayawardhana: It is a clue that most likely, these high energy neutrinos come either from jets of particles that are
accelerated by super massive
black holes at the hearts of galaxies, or from really gigantic stars that explode at the end of their lives that also produce a phenomenon we call gamma ray bursts, which also might
accelerate particles to very high speeds and energies.
These mergers produce shock waves, which propagate through the clusters, reaccelerating particles previously
accelerated by supermassive
black holes in the galactic nuclei.

accelerated by more than 250,000 miles per hour a year as they orbited the
black hole at the center of the Milky Way.
The existence of
black holes can be proven because matter is greatly
accelerated by the gravitational force and thus emits particularly high - energy radiation.»

black hole that can
accelerate and eject stars from the galaxy
by disrupting an original binary star.

accelerating due to gravitational scattering caused
by the intermediate - mass
black hole.

black holes, and we know GCR are
accelerated by supernovae.
