Another Abundance Inhomogeneity in the South East Limb of the Cygnus Loop
Hiroshi Tsunemi, Masashi Kimura, Hiroyuki Uchida +2
We have observed the south-east (SE) limb of the Cygnus Loop with {\it Suzaku}. Our spatially-resolved spectroscopic study shows that a one- non-equilibrium ionizati…
Suzaku Observations across the Cygnus Loop from the Northeastern to the Southwestern Rim
Masashi Kimura, Hiroshi Tsunemi, Satoru Katsuda +1
We have observed the Cygnus Loop from the northeast (NE) rim to the southwest (SW) rim using Suzaku in 10 pointings that is just north of previous XMM-Newton observations. The obse…
The Plasma Structure of the Southwestern Region of the Cygnus Loop with the XMM-Newton Observatory
Hiroyuki Uchida, Hiroshi Tsunemi, Satoru Katsuda +1
We observed the southwestern region of the Cygnus Loop in two pointings with \textit{XMM-Newton}. The region observed is called the "blow-out" region that is extended further in th…
Anisotropic Inflation from Vector Impurity
Sugumi Kanno, Masashi Kimura, Jiro Soda +1
We study an inflationary scenario with a vector impurity. We show that the universe undergoes anisotropic inflationary expansion due to a preferred direction determined by the vect…
Chandra Observations of the Northeastern Rim of the Cygnus Loop
Satoru Katsuda, Hiroshi Tsunemi, Masashi Kimura +1
We present results from spatially resolved spectral analyses of the northeastern (NE) rim of the Cygnus Loop supernova remnant (SNR) based on two Chandra observations. One pointing…
Analyticity of Event Horizons of Five-Dimensional Multi-Black Holes with Non-Trivial Asymptotic Structure
Masashi Kimura
We show that there exist five-dimensional multi-black hole solutions which have analytic event horizons when the space-time has non-trivial asymptotic structure, unlike the case of…
