Evidence for Resonance Line Scattering in the Suzaku X-ray Spectrum of the Cygnus Loop
Emi Miyata, Kuniaki Masai, John P. Hughes
We present an analysis of the Suzaku observation of the northeastern rim of the Cygnus Loop supernova remnant. The high detection efficiency together with the high spectral resolut…
Core Structure of Intracluster Gas: Effects of Radiative Cooling on Core Sizes
Takuya Akahori, Kuniaki Masai
We investigate the core structure of radiatively cooling intracluster gas, using a hydrodynamics code. We calculate evolution of model clusters of the initial core radii 160--300 k…
L_X-T Relation and Related Properties of Galaxy Clusters
Naomi Ota, Tetsu Kitayama, Kuniaki Masai +1
An observational approach is presented to constrain the global structure and evolution of the intracluster medium based on the ROSAT and ASCA distant cluster sample. From statistic…
Core Structure of Intracluster Gas: Isothermal Hydrostatic Equilibrium
Takuya Akahori, Kuniaki Masai
We investigate core structures of X-ray emitting intracluster gas based on the so-called beta-model, which is an isothermal hydrostatic model often used in observational studies. W…
Quasi-hydrostatic intracluster gas under radiative cooling
Kuniaki Masai, Tetsu Kitayama
Quasi-hydrostatic cooling of the intracluster gas is studied. In the quasi-hydrostatic model, work done by gravity on the inflow gas with dP \neq 0, where P is the gas pressure, is…
ASCA Observations of the Supernova Remnant IC 443: Thermal Structure and Detection of Overionized Plasma
Masahiro Kawasaki, Masanobu Ozaki, Fumiaki Nagase +3
We present the results of X-ray spatial and spectral studies of the ``mixed-morphology'' supernova remnant IC 443 using ASCA. IC 443 has a center-filled image in X-ray band, contra…
Non-Equilibrium Ionization States of GRB Environments
D. Yonetoku, T. Murakami, K. Masai +3
Iron spectral features are thought to be the best tracer of a progenitor of gamma-ray bursts (GRBs). The detections of spectral features such as an iron line and/or a Radiative Rec…
