Are you hinting something regarding the presence of relativistic jets? Doesn't the inverse square law work anyways, both for a spherical radiation and for a beamed one?
I've got a small homework question that goes:
Which would be more dangerous and why: Eta Carina exploding as a gamma-ray burst, or
the black hole at the Galactic centre accreting material at the same rate as a typical luminous
Seyfert galaxy?
I have simply estimated the flux from both of...
You mean that if I calculate the photons per m^2 per second for the optical one whatever result I'll get the 1/10th of that number will be the photons per m^2 per second of the X-Ray one?
I've got to solve this problem and I am having quite an hard time figuring out how... Sorry, but I think I need help:
"An astronomer takes a spectrum of a distant quasar using a 4m telescope. With an exposure
time of one hour, the optical spectrum contains about 10,000 photons. The source...
