The Government has offered Australia's three mobile operators, and vividwireless, renewal of their existing spectrum allocated on 15 year licences in the late 90s and early 2000s at set prices, while the Government expects to rake in $3 billion.
Dr. Fujioka stated that the pellet was turned into "… a source of [immensely powerful] x-rays similar to those from an accretion disk around a black hole.” [ScienceNOW]
The accretion disk is the cloud of matter that surrounds a black hole.
Because astronomers cannot see a black hole directly (because all electromagnetic radiation [light] is turned inward by the giant gravitational field generated by the extremely dense black hole), they are forced to analyze its accretion disk.
The accretion disk becomes visible in x-rays (one type of electromagnetic radiation, or light) when energy is generated by the immense gravitational field within a black hole.
Thus, the work by Dr. Fujioka and his colleagues will help scientists learn more about the processes in and around black holes.
The ScienceNOW article states, “By measuring the energy lost from the photoionization, the researchers could measure total energy emitted from the implosion and use it to improve their understanding of the behavior of x-rays emitted by accretion disks.”
