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…
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…
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…
Horizons of Coalescing Black Holes on Eguchi-Hanson Space
Chul-Moon Yoo, Hideki Ishihara, Masashi Kimura +2
Using the numerical method, we study dynamics of coalescing black holes on the Eguchi-Hanson base space. Effects of a difference in spacetime topology on the black hole dynamics is…
Supersymmetric Black Rings on Eguchi-Hanson Space
Shinya Tomizawa, Hideki Ishihara, Masashi Kimura +1
We construct new supersymmetric black ring solutions on the Eguchi-Hanson base space as solutions of five-dimensional minimal supergravity. The solutions have the same two angular…
