Black Holes … gamma ray bursts and things

9 April 2011

At www.physorg.com/print221457830.html we have an interesting interpretation of an astronomical event – two neutron stars merge and within mill-seconds, it is said, form a black hole. It can't of course be seen but is thought to happen, even the neutron stars are hypothetical as far as composition is concerned. What is known for sure is that such an event coincides with the formation of a strong magnetic field along the rotational axis which creates a jet that shoots ultra hot matter into space – a gamma ray burst event. The consensus theory included a computer simulation of what might have happened.

At www.physorg.com/print221460720.html is a similar, or a slewed version of the same kind of thinking – a gamma ray burst observed by the Chandra X-Ray Observatory, a long lived event in a distant galaxy but extremely luminous. It is connected, it continues, with the theory of an exploding star and the formation of a black hole. 

The same story, or a variation, can be seen at www.sciencenews.org/generic/id/72398/title/Baffling_blowup_in_distant_ga…
