This feature was thought to be radiation from a beam of electrons accelerated to nearly the speed of light as a result of processes occurring in or near the disk of material spiraling into the purported black hole.
Matter stripped from a companion star by a black hole can form a flat, pancake-like structure, called an "accretion disk". As material spirals toward the inner edge of the accretion disk, it is heated by the immense gravity of the black hole, which causes it to radiate in X-rays.
Theorists also believed that the infalling material, spiraling onto the neutron star, sets it spinning rapidly.
The material spirals inward, applying a torque to the pulsar's magnetic field and spinning it up.
Although the black holes themselves emit no radiation, material spiraling into them from orbiting stars gets heated to such extreme temperatures that it emits x-rays (inset).
The instruments are expected to reveal details about gases trapped in galaxy clusters and wafting through supernova remnants as well as the turbulent streams of material spiraling away from black holes.
New observations from NASA's Rossi X-ray Timing Explorer (XTE) satellite, reported in International Astronomical Union (IAU) Circulars and in scientific talks, seem to show a millisecond pulsar's birth process: infalling material spiraling down onto a neutron star, spinning it like a top and spewing out x-rays.
