Diffuse x-ray emission from the northern arc of loop I observed with suzaku
Masahiro Akita, Jun Kataoka, Makoto Arimoto +4
After discovery of the Fermi bubbles, giant structures observed in radio to X-rays have been discussed as possi- ble evidence of past activities in the Galactic Center (GC). We rep…
The origins of the gamma-ray flux variations of NGC 1275 based on 8 years of Fermi-LAT observations
K. Tanada, J. Kataoka, M. Arimoto +4
We present an analysis of 8 years of Fermi-LAT ( > 0.1 GeV) gamma-ray data obtained for the radio galaxy NGC 1275. The gamma-ray flux from NGC 1275 is highly variable on short (~ d…
X-ray and Gamma-ray Observations of the Fermi Bubbles and NPS/Loop I Structures
Jun Kataoka, Yoshiaki Sofue, Yoshiyuki Inoue +3
The Fermi bubbles were possibly created by large injections of energy into the Galactic Center (GC), either by an active galactic nucleus (AGN) or by nuclear starburst more than ~1…
Galactic-Center Hyper-Shell Model for the North Polar Spurs
Y. Sofue, A. Habe, J. Kataoka +5
The bipolar-hyper shell (BHS) model for the North Polar Spurs (NPS-E, -W, and Loop I) and counter southern spurs (SPS-E and -W) is revisited based on numerical hydrodynamical simul…
