On the Galactic plane that is. Part of my ongoing research focuses on the identification of gamma-ray sources discovered by the Fermi telescope. The sources are first observed at energies a million times greater than medical X-rays. The next step involves finding the actual source of the energy release with optical, radio, and X-ray telescopes. Of the 205 sources spotted by Fermi so far, 37 have no obvious counterpart at other wavelengths. As part of our work, we have recently found that at least 4 of these sources correspond to massive black holes or AGNs that lie behind the Galactic plane. You can read the article here.
