Cosmic Magnifying Lens Inner Jets Black Holes
2017/9/5
"We have known about the existence of these clumps of material streaming along black hole jets, and that they move close to the speed of light, but not much is known about their internal structure or ...
Astronomers have found an enormous, glowing blob of gas in the distant universe, with no obvious source of power for the light it is emitting. Called an "enormous Lyman-alpha nebula" (ELAN), it is the...

I summarize X-ray diagnostic studies of cosmic star formation
history in terms of evolutionary schemes for X-ray binary evolution in
normal galaxies with evolving star formation. Deep X-ray imaging ...
