A team of physicists have proposed a new cosmological model – dubbed the "black hole universe" – that suggests that our ...

Researchers have finally confirmed that black holes spin. By watching the radio jet of the black hole at the center of the galaxy Messier 87, researchers were able to watch it tilt, a movement ...

Abstract: This paper proposes a novel Doppler shift-compensated Frequency Modulated Continuous Wave (DSC-FMCW) algorithm for achieving high-precision Time of Arrival (TOA) estimation of moving targets ...

A supermassive black hole lurking at the heart of a relatively close galaxy is firing off a rapid-fire slew of ultrafast gas "bullets" into the surrounding galaxy. This is the conclusion of an ...

Researchers have discovered that ultra-fast wind surrounding a supermassive black hole is not smooth and continuous as previously assumed, but instead resembles a rapid-fire stream of gas "bullets.

Measurements of wind in a luminous galactic core reveal dense pockets of gas — a finding that calls for a rethink of how black holes interact with their host galaxies. Read the paper ...

A study published in Nature has established a new benchmark in modeling the universe's most extreme events: the collisions of black holes and neutron stars. This research, led by Professor Jan ...

At least, that’s the conclusion of an international team of researchers that applied geometric structures inspired by particle physics and string theory to the behavior of black holes when the ...

A new study achieves unprecedented accuracy in modelling extreme cosmic events like black hole and neutron star collisions by calculating the fifth post-Minkowskian (5PM) order, crucial for ...
