high energy photons are emitted from accretion disc of black hole...are nuclear particles like electrons,protons also emitted in this process? are there any observation of particles emitted?
There are considerable differences between these models concerning the detailed physics in the various regions (torus, disk, jets), and also observational evidence of considerable variation in Nature. See also this, this, this, this, and this, for example. Accounting properly for all the energy and momentum is a major issue.drain energy from the ions as a result of collisionless plasma microinstabilities [in a surrounding region, I think]. Consequently, the accreting gas collapses to form a geometrically thin disk at small radii and is able to cool before reaching the black hole. The accretion disk is not a standard disk, however, because the radial disk structure is modified by a magnetic torque which drives a jet and which is primarily responsible for angular momentum transport.
Chris Hillman said:Well, current models typically contain such elements as collimated jets "fed" by an accretion disk which is "fed" by a torus of surrounding matter (perhaps drawn off a companion); see http://chandra.harvard.edu/resources/illustrations/agn/agn_ill_6.html from the Chandra team (Astronomy, Harvard). I am not sure what you mean by "emitted by", but as I understand, collimated jets would probably contain ions ejected at high velocity from the vicinity of the hole.
For example, this paper assumes that electrons

Particles from a black hole refer to any matter or energy that is emitted from the event horizon of a black hole. This can include photons, electrons, and other subatomic particles that are accelerated to high speeds near the black hole.
Particles from a black hole are formed through a process known as Hawking radiation. This is when pairs of particles and antiparticles are created near the event horizon, with one particle being pulled into the black hole and the other escaping as radiation.
Yes, particles from a black hole can escape the black hole's strong gravitational pull through Hawking radiation. However, this process is very slow for large black holes and only becomes significant for smaller black holes.
Particles from a black hole can have a significant impact on their surroundings. For example, they can provide energy and contribute to the heating of interstellar gas. They can also interact with other particles and create intense radiation, such as X-rays and gamma rays.
No, particles from a black hole are not dangerous to humans. They are usually too far away and too small to cause any harm. In addition, the Earth's atmosphere protects us from most of the high-energy particles that may be emitted from a black hole.
