Mass of black holes determines star formation history
... mass of the black hole that is guilty of shutting down star formation as the galaxy evolves. The name active galactic nuclei (AGN) is used to describe a very bright region at the centre of a galaxy and as strong emitters of X-rays, ultraviolet and...

Molecular oxygen detected for the first time in another galaxy
... time detected molecular oxygen beyond the Milky Way and it has turned up in the outflows of gas near an Active Galactic Nuclei (AGN) - one of the most powerful objects in the Universe. As humans, we rely on it to survive and it is found ubiquitously...

Powerful outburst points to new class of high-energy transients
...1047 Joules. There is one type of phenomena that is capable of producing energy to this degree, however and that is Active Galactic Nuclei (AGN). AGN are the power houses at the centres of galaxies and they are thought to result from the accretion...

Three massive black holes caught in the act of merging
... been questioned by some. One of the three systems in question is a trio of AGN that are collectively known as SDSS J0849+1114. AGN is short for Active Galactic Nuclei and they are thought to be powered by centrally located supermassive black holes...

Scientists uncover common origin for ultrahigh-energy particles
...-energy jets that the cosmic rays shoot from at almost the speed of light, are associated with "active galactic nuclei" – the super-radiating core region around a central supermassive black hole. Most galaxies contain at least one...

First-ever photo proof of powerful jet emerging from colliding galaxies
...in high-energy physics studies. Jets were thought to be born from older, elliptical-shaped galaxies with an active galactic nucleus (AGN), which is a super-massive black hole that resides at its center. As a point of reference, scientists believe all...
