The researchers, including Caltech Professor of Physics Jamie Bock and Caltech Senior Postdoctoral Fellow Michael Zemcov, say that the best explanation is that the cosmic light — described
in a paper published November 7
in the journal Science — originates from stars that were stripped away from their parent
galaxies and flung out into space as those
galaxies collided and merged with other
galaxies.
In a simulation of two
colliding galaxies (sequence, top to bottom), a central quasar blows gas deep into space.
