Blazars shed light on black hole physics

Blazars are found in the middle of galaxies where supermassive black holes emit powerful jets of charged particles, at velocities close to the speed of light, directly towards the Earth.

Italian astronomers using the gamma ray imaging detector on the Astro-rivelatore Gamma a Immagini Leggero (AGILE) satellite noticed marked changes in the behaviour of eight blazars.

The team then trained a number of ground and space-based telescopes from other observatories on each blazer, enabling them to observe the jets in a range of energies from gamma ray to radio wavelengths.

Blazars typically emit energy in a wide range of frequencies, ejected in two narrow, oppositely-directed beams.

When a large amount of matter falls into the central black hole, the blazer's jets increase in intensity.

This is interesting, Blazars are what I know the least of when it comes to astrophysics.

If anyone else can provide more explanations on this phenomena please do so
thasnk

Hope this may help a bit www.space.com...

You know this phenomenon can be copied if studied sufficiently and turned into a very efficient sub-light speed space propulsion system.

Look at this
en.wikipedia.org...

It's generating a single jet.... Maybe this is how galaxies can 'actively' move around in space other than the gravitational influence of other galaxies..
