The process that makes black holes.
Armed with state-of-the-art supercomputer models, scientists have shown that colliding neutron stars can produce the energetic jet required for a gamma-ray burst. Earlier simulations demonstrated that mergers could make black holes.
Others had shown that the high-speed particle jets needed to make a gamma-ray burst would continue if placed in the swirling wreckage of a recent merger.
Now, the simulations reveal the middle step of the process--how the merging stars' magnetic field organizes itself into outwardly directed components capable of forming a jet.
The Damiana supercomputer at Germany's Max Planck Institute for Gravitational Physics needed six weeks to reveal the details of a process that unfolds in just 35 thousandths of a second--less than the blink of an eye.
Black Hole Consumes a Super-Jupiter.
Astronomers using ESA's Integral and XMM-Newton space telescopes, NASA's Swift and the MAXI (Monitor of All-sky X-ray Image) instrument on the International Space Station have made the first detection of a substellar object being disrupted by a black hole.
The discovery was made in the 47 million-light-year-distant galaxy, NGC 4845, where a substellar object moving through space encountered the black hole.
During this encouter, debris becomes heated and emits a blast of X-ray radiation before fading away.
The object lies in the mass range of 14--30 Jupiter masses, corresponding to either a brown dwarf or a large gas planet.credit: ESA.
