blazar's random findings

Scientists say they have unlocked some of the secrets behind black holes, the gravitational fields known for sucking up light and stars from the Universe. (via BBC NEWS | Science/Nature | Black holes reveal more secrets)

Using almost every type of telescope known to humankind, Prof Marscher believes he has worked out where and how the jets - or blazars - are formed.

Using an array of 10 powerful radio telescopes, aimed at the galaxy BL Lacertae, the researchers studied a black hole just as it was sending forth a blazar jet.

It’s a paradox of galactic proportions: from the midst of black holes, born of collapsed stars and known for their intense matter- and light-trapping gravity, astronomers have long detected massive jets of hot, ionized gas — known as blazars — shooting out at nearly the speed of light.

Another target: blazars or marathon gamma ray bursts. Blazars are thought to come from supermassive black holes at the centers of young, active galaxies. “A blazar episode lasts for 10 million to 100 million years,” explains Alan Marscher, an astrophysicist at Boston University who heads the university’s blazar research group. In the process, they generate telltale jets of particles that stretch into space for 10 million to 100 million light-years. Data from GLAST, combined with information from radio-telescopes and visible light, will help scientists tease out the processes behind these galactic beacons.
