The origins of a torus in a galactic nucleus

(PhysOrg.com) -- Quasars are among the most energetic objects in the universe, with some of them as luminous as ten thousand Milky Way galaxies. Quasars are thought to have massive black holes at their cores, and astronomers ...

'God Particle' Nobel ticks boson box for CERN

The reflected glory of a Nobel prize for the minds behind the "God particle" sent champagne corks popping at Europe's top physics lab CERN Tuesday, vindicating its landmark discovery a year ago.

Most distant blazar is a high-energy astrophysics puzzle

(Phys.org) —Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of the blazar known as PKS 1424+240 show that it is the most distant known source of very high-energy ...

New model suggests how the brain might stay in balance

(PhysOrg.com) -- Physicists have theorized for decades about how neural networks might be able to accomplish the incredibly complex calculations the human brain performs all the time. But simply stabilizing such a powerful ...

Searching for dark matter with the world's most sensitive radio

Since the 1960s there has been plenty of evidence to support the existence of dark matter through astrophysical and cosmological observations, and at this point we're very confident that it exists. The question remains, though: ...

A model for describing the hydrodynamics of crowds

Precise simulations of the movement and behavior of crowds can be vital to the production of digital sequences or the creation of large structures for crowd management. However, the ability to quantitatively predict the collective ...
