Suzaku Observations of the Diffuse X-Ray Emission across the Fermi Bubbles' Edges
Jun Kataoka,M. Tahara,Tomonori Totani,Yoshiaki Sofue,Łukasz Stawarz,Y. Takahashi,Y. Takeuchi,Hiroshi Tsunemi,Masashi Kimura,Yoh Takei,C. C. Cheung,Yoshiyuki Inoue,Takeshi Nakamori +12 more
TL;DR: Suzaku X-ray observations along two edge regions of the Fermi Bubbles were presented in this article, with eight 20k pointings across the northern part of the North Polar Spur (NPS) surrounding the north bubble and six across the southernmost edge of the south bubble.
