Comment on "An X-ray chimney extending hundreds of parsecs above and below the Galactic Centre" (2019, Nature, 567, 34)
Shinya Nakashima, Katsuji Koyama, Q. Daniel Wang
A recent article "An X-ray chimney extending hundreds of parsecs above and below the Galactic Centre" (2019, Nature, 567, 34) reported the detection of chimney-like X-ray-emitting…
X-ray Observation of a Magnetized Hot Gas Outflow in the Galactic Center Region
Shinya Nakashima, Katsuji Koyama, Q. Daniel Wang +1
We report the discovery of a scale X-ray plume in the northern Galactic Center (GC) region observed with Suzaku. The plume is located at (, ) ($0\mbox{$.\!\!…
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…
Spatial distribution of the Milky Way hot gaseous halo constrained by Suzaku X-ray observations
Shinya Nakashima, Yoshiyuki Inoue, Noriko Yamasaki +3
The formation mechanism of the hot gaseous halo associated with the Milky Way Galaxy is still under debate. We report new observational constraints on the gaseous halo using 107 li…
The Quiescent Intracluster Medium in the Core of the Perseus Cluster
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +213
Clusters of galaxies are the most massive gravitationally-bound objects in the Universe and are still forming. They are thus important probes of cosmological parameters and a host…
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…
