Astronomers using the NASA Fermi Gamma-ray Space Telescope to study what they thought were two different classes of black-hole-powered galaxies known as blazars now believe that they may be one and the same.

First Gamma Ray Study Gravitational Lens
2014-01-06 15:27:47

New research from an international team of researchers using NASA's Fermi telescope reports the first-ever gamma ray study of the cosmic phenomenon.

ALMA Observatory Reveals Black Hole's Eating Habits
2013-10-16 10:12:37

New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) in the high-altitude Atacama Desert of Chile have revealed new details about the powerful molecular-gas jets that stream out of supermassive black holes.

Measuring All Light Since Big Bang May Provide Answers To Evolution Of Universe
2013-05-24 14:07:39

Measuring the number and energy of each particle of light or photon since the Big Bang could provide secrets about the nature and evolution of the Universe, such as how similar or different ancient galaxies were compared to the galaxies today.

Most Distant Source Of High-Energy Gamma Rays Comes From Distant Blazar

A team of physicists has made new observations of the blazar known as PKS 1424+240 that reveal it is the most distant known source of very high-energy gamma rays.

Origin Of Gamma Ray Flare Far Away From Their Galaxy’s Black Hole
2013-01-08 13:18:26

The source of a gamma ray flare that shot past Earth throughout much of 2011 has been discovered, and contrary to popular theory, they did not occur close to their galaxy’s central black hole, say NASA officials.

All Black Holes Launch Fundamentally Similar High-Speed Jets

Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...

Active Galaxy -- An active galaxy is a galaxy where a significant fraction of the energy output is not emitted from normal stellar populations or interstellar gas. This energy, depending on the active galaxy type, can be emitted across most of the electromagnetic spectrum, as infrared, radio waves, UV, X-ray and gamma rays. Frequently, the abbreviation AGN (Active Galactic Nuclei) is used, since most of the active galaxies emit most of their radiation from a narrow region in their...
