The elliptical galaxy 3C186, located about 8 billion years from Earth, is most likely the result of a merger of two galaxies. This is supported by arc-shaped tidal tails, usually produced by a gravitational tug between two colliding galaxies, identified by M. Chiaberge et al. The merger of the galaxies also led to a merger of the two supermassive black holes in their centers, and the resultant black hole was then kicked out of its parent galaxy by the gravitational waves created by the merger. The bright, star-like looking quasar can be seen in the center of the image. Its former host galaxy is the faint, extended object behind it. Image credit: NASA / ESA / M. Chiaberge, STScI.

The tiny temperature fluctuations of the cosmic microwave background, shown here as color, trace primordial density fluctuations in the early universe that seed the later growth of galaxies. Gravitational waves from inflation are expected to produce much a fainter pattern that includes twisting B-mode polarization, consistent with the B-mode polarization pattern observed by BICEP2, which is shown here as black lines. The line segments show the polarization strength and orientation at different spots on the sky. Image credit: BICEP2 Collaboration.
