Now astronomers have discovered that this chaotic region is crossed by a complex network of magnetic fields , which have a complex structure in the form of tunnels through which some particles manage to escape from the gravitational well . For the first time, the presence of these gravitational fields has been identified so close to a black hole.
A team led by Philippe Laurent, a researcher at the CEA (Commissariat à l'atomique énergie) in Saclay (France), made the discovery by studying the s i binary stema of Cygnus X-1, where the gravity of the black hole is dismembering Star accompanying it. The results suggest that this magnetic field is strong enough to pull particles out of the gravitational well and pump them out, projecting a jet of matter into the vacuum of space. The particles that make up these jets gain speed through spiral paths , which affects a property of radiation known as polarization.
