Possible origins of UHEs:
Therefor the source of UHEs must be outside our galaxy, but closer than 30 million light years away, and very violently energetic.
|Do the highest energy Cosmic Rays come from objects such as this? On the left is a radio telescope image of the active galaxy NGC-4261. The width of the image covers a region of space 88,000 light years across.Notice the bright orange jets that spray out above and below the centre. To the right is a close up image from the Hubble Space Telescope covering just 400 light years. It shows a doughnut shaped ring at the centre. This ring is thought to orbit a giant black hole with a mass more than a hundred million times that of our sun. From http://ast.leeds.ac.uk/haverah/origin.shtml|
