Surprisingly strong magnetic fields challenge black holes' pull

Academics / General Science : Science Codex

A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surveyed, the magnetic field strength matched the force...

Astronomers see black hole raging red

Academics / General Science : ScienceDaily: Science Society

Violent red flashes, lasting just fractions of a second, have been observed during one of the brightest black hole outbursts in recent years. In June 2015, a black hole called V404 Cygni underwent dramatic brightening for about two ...

Extreme jet ejections from the black hole X-ray binary V404 Cygni

Academics / Astronomy : Physorg: Astronomy

A black hole X-ray binary (BHXB) is a black hole orbiting a normal star. When matter from the normal star accretes onto the black hole, a jet of charged particles is ejected at relativistic (near-light) speeds, and these particles e...

Surprisingly strong magnetic fields can match black holes' pull: Long-neglected magnetic fields have an unexpected presence

A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surveyed, the magnetic field strength matched the force...

Massive V404 Cygni Black Hole Wakes Up And Swallows A Star

News : Huffington Post

A black hole has woken up... and it's hungry. The European Space Agency says V404 Cygni, a binary system of a black hole and a star, has gone from practically invisible to one of the brightest objects in the high-energy sky (space a...
