Exploring Hot Gas at Junctions of Galaxy Filaments with Suzaku
Ikuyuki Mitsuishi, Hajime Kawahara, Norio Sekiya +3
We performed five pointing observations with Suzaku to search for hot gases associated with the junctions of galaxy filaments where no significant diffuse X-ray sources were detect…
Starspots - Transit Depth Relation of the Evaporating Planet Candidate KIC 12557548b
Hajime Kawahara, Teruyuki Hirano, Kenji Kurosaki +2
Violent variation of transit depths and an ingress-egress asymmetry of the transit light curve discovered in KIC 12557548 have been interpreted as evidences of a catastrophic evapo…
Validity of Hydrostatic Equilibrium in Galaxy Clusters from Cosmological Hydrodynamical Simulations
Daichi Suto, Hajime Kawahara, Tetsu Kitayama +3
We examine the validity of the hydrostatic equilibrium (HSE) assumption for galaxy clusters using one of the highest-resolution cosmological hydrodynamical simulations. We define a…
