Scientists Use Several Telescopes to Observe Giant Radio Galaxy

Astronomers have used two Australian radio telescopes and several optical telescopes to study complex mechanisms that are fuelling jets of material blasting away from a black hole 55 million times more massive than the Sun.

Study Explains Why Extragalactic Jets Disintegrate into Huge Plumes

University of Leeds researchers have mathematically examined plasma jets from supermassive black holes to determine why certain types of jets disintegrate into huge plumes.

Research on the Collective Excitations of an Exciton Condensate

Excitons are pairs of holes and electrons present inside a solid material that together act like just one particle. For a long time, it has been assumed that when a number of such excitons exist in the same piece of matter, they can produce a single giant quantum state known as a Bose-Einstein condensate – the same process which is considered to be responsible for a metal losing all of its electrical resistance when it develops into a superconductor, for instance.

Stanford Astrophysicist Develops Software that Models Incompatible Astronomical Observations

A recent study in Science cast doubt on one formerly favored explanation for why an abundance of positrons – the antimatter counterparts of electrons – has been found near Earth. Two nearby collapsed stars, it turns out, aren’t likely to blame because their positrons couldn’t have traveled as far as the Earth.

Black Holes Have Significantly Weaker Magnetic Fields than Previously Thought

Black holes are famous for their muscle: an intense gravitational pull known to gobble up entire stars and launch streams of matter into space at almost the speed of light.

Scientists Discover Magnetic Monopoles in Superfluid Helium Droplets

The startling similarity between the physical laws describing electric phenomena and those describing magnetic phenomena has been known since the 19th century. However, one piece that would make the two perfectly symmetric was missing: magnetic monopoles.
