Swift XMM-Newton Satellites Tune Into a Middleweight Black Hole
"Intermediate-mass black holes contain between 100 and 10,000 times the sun's mass," explained Tod Strohmayer, an astrophysicist at Goddard. "We observe the heavyweight black holes...

Read more'Dropouts' pinpoint earliest galaxies
The finding is the first age-confirmation of a so-called dropout galaxy at that distant time and pinpoints when an era called the reionization epoch likely began. The research will be published in a D...
Physics and Astronomy | Read moreStarburst galaxy sheds light on longstanding cosmic mystery
The gamma rays observed by the team have energies more than a trillion times higher than the energy of visible light and are the highest-energy photons ever detected from a galaxy undergoing large amo...
