... 2008 October 21 . A Dark Pulsar in CTA 1 . Credit: NASA , S. Pineault ( DRAO ) . Explanation: Where's the pulsar? Previously, the nebula CTA 1 showed an expanding supernova remnant , a jet , and a point source expected to be a pulsar -- a rotating neutron star producing pulses at radio energies. ... Now NASA's recently deployed Fermi Space Telescope has solved the mystery with some of its initial observations indicating that the point source is pulsing at gamma-ray energies . ...

As already mentioned in the previous section, the effect of Compton scattering of photons through (backward scattering) opens the possibility to generate intensive high energy photon beams. ... Here we use our results for Compton scattering to calculate the energy spectrum of backward scattered photons in the case of unpolarized incident laser photons and electrons. ... If we denote the 4-momenta of the incident photon, incident electron and scattered photon, respectively, by , and , then we get . ...

... September 5, 1998 . The Pulsar Powered Crab . Credit: J. Hester and P. Scowen ( ASU ), NASA . ... Using a stunning series of visible light images taken with the Hubble Space Telescope (HST) , astronomers have discovered spectacular pulsar powered motions within the Crab nebula. Highlights of this HST Crab "movie" show wisps of material moving away from the pulsar at half the speed of light, a scintillating halo, and an intense knot of emission dancing, sprite-like, above the pulsar's pole. ...
