Two Missions, One Microquasar

摘要

It has been on the suspect list for more than 30 years, but now we know for sure, smoking gun and all, that x-ray source number 3 in the constellation of Cygnus (Cyg X-3) emits gamma rays. After many near (and wide-of-the-mark) misses, we now have incontrovertible evidence coming from two independent gamma-ray telescopes, AGILE (1) and Fermi (2), the latter reported on page 1512 of this issue.
