Unveiling Exotic Celestial Activity in the Universe
ORAL
Abstract
We have successfully carried out an observational program with the Chandra X-ray Observatory to determine the nature of 8 unidentified celestial gamma-ray sources. Based on intelligent parameter selection, we expect our observation data to be dominated by highly magnetized neutron stars, ~10^12 Guass, with a possible inclusion of X-ray binaries. For each source, we calculate X-ray fluxes in a range of energy bands (0.5-7keV), and search for counterparts at lower energies (e.g., Optical, IR). This multi-wavelength dataset is then prepped to be analyzed by a machine learning classification tool to determine the nature of these sources. For bright X-ray sources, we also extract X-ray spectra which allows for a more accurate source identification. Our preliminary results conclude that the unidentified Fermi sources 2FGL J1839.0-0102 and 2FGL J0340.5+5307 host the brightest X-ray sources of our eight observations.
