Multiband Diagnostics of Unidentified 1FGL Sources with Suzaku and Swift X-ray Observations
Y. Takeuchi, J. Kataoka, K. Maeda +3
We have analyzed all the archival X-ray data of 134 unidentified (unID) gammaray sources listed in the first Fermi/LAT (1FGL) catalog and subsequently followed up by Swift/XRT. We…
X-ray and Radio Follow-up Observations of High-Redshift Blazar Candidates in the Fermi-LAT Unassociated Source Population
Y. Takahashi, J. Kataoka, K. Niinuma +6
We report on the results of X-ray and radio follow-up observations of two GeV gamma-ray sources 2FGL J0923.5+1508 and 2FGL J1502.1+5548, selected as candidates for high-redshift bl…
Suzaku X-ray Imaging of the Extended Lobe in the Giant Radio Galaxy NGC6251 Associated with the Fermi-LAT Source 2FGLJ1629.4+8236
Y. Takeuchi, J. Kataoka, L. Stawarz +7
We report the results of a Suzaku X-ray imaging study of NGC6251, a nearby giant radio galaxy with intermediate FR I/II radio properties. Our pointing direction was centered on the…
Discovery of an unidentified Fermi object as a black widow-like millisecond pulsar
A. K. H. Kong, R. H. H. Huang, K. S. Cheng +10
The Fermi Gamma-ray Space Telescope has revolutionized our knowledge of the gamma-ray pulsar population, leading to the discovery of almost 100 gamma-ray pulsars and dozens of gamm…
Suzaku X-ray Follow-up Observations of Seven Unassociated Fermi-LAT Gamma-ray Sources at High Galactic Latitudes
Yosuke Takahashi, Jun Kataoka, Takeshi Nakamori +8
We report on our second-year campaign of X-ray follow-up observations of unidentified Fermi-LAT γ-ray sources at high Galactic latitudes (|b|>10 degree) using the X-ray Imaging Spe…
Broad Line Radio Galaxies Observed with Fermi-LAT: The Origin of the GeV Gamma-Ray Emission
J. Kataoka, L. Stawarz, Y. Takahashi +15
We report on a detailed investigation of the gamma-ray emission from 18 broad line radio galaxies (BLRGs) based on two years of Fermi Large Area Telescope (LAT) data. We confirm th…
Unraveling the Nature of Unidentified High Galactic Latitude Fermi/LAT Gamma-ray Sources with Suzaku
Koto Maeda, Jun Kataoka, Takeshi Nakamori +13
We report on the results of deep X-ray follow-up observations of four unidentified Fermi/LAT gamma-ray sources at high Galactic latitudes using Suzaku. The studied objects were det…
