Polarized blazar X-rays imply particle acceleration in shocks.

Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to around 1 TeV. Although the jets are known to be ultimately powered by a supermassive black hole, how the particles are accelerated to such high energies has been an unanswered question. The process must be related to the magnetic field, which can be probed by observations of the polarization of light from the jets.

LIGHTCURVE ANALYSIS OF THE HUNGARIA BINARY 7958 LEAKEY.

The Hungaria asteroid 7958 Leakey is a known binary (Warner et al., 2012). It was observed in 2015 to confirm and refine the original periods for the primary rotation and satellite orbit.
