TL;DR: The Fermi Large Area Telescope has detected a variable high-energy source coinciding with the position of the x-ray binary and microquasar Cygnus X-3, opening new areas in which to study the formation of relativistic jets.
Journal ArticleDOI
The distortion of distant galaxy images by large-scale structure
TL;DR: In this paper, a prescription for quantifying the galaxy distortion and a propagation equation for its evolution in an inhomogeneous universe is derived, and a measurement of galaxy distortion over patches of the sky up to a few square degrees in size is given.
