1. APOD: 2014 February 24 - The Cloudy Cores of Active Galaxies
... 2014 February 24 . The Cloudy Cores of Active Galaxies . Image Credit: NASA's GSFC , W. Steffen ( UNAM ) . Explanation: What would it look like to travel to the center of an active galaxy? Most galactic centers are thought to house black hole s millions of times more massive than our Sun. The spaces surrounding these supermassive black holes may be far from dormant, however, flickering in many colors and earning the entire object class the title of Active Galactic Nuclei (AGN). ...

It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

11. Continent-sized radio telescope takes close-ups of Fermi active galaxies |
... Continent-sized radio telescope takes close-ups of Fermi active galaxies . Observations solidify a theory about radio-emitting jets emanating from supermassive black holes at the centers of active galaxies. ... The study solidifies the link between an active galaxy's gamma-ray emissions and its powerful radio-emitting jets. ... All this points to the team's conclusion that the portion of an active galaxy's radio jet closest to the galaxy's core is also the source of the gamma-rays Fermi detects. ...

... 2 April 1999 . The Nobeyama Radioheliograph data show that in the microwave range, besides large-scale trans-equatorial chains (see, e.g., the May 11-15, 1993 and November 1-4, 1993 events), there are also many examples displaying large and strongly evolving "longitudinal" or "internal" chains connecting remote active regions inside an active zone in one (northern or southern) hemisphere (the August 20-September 3, 1998 event). ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
