Density Profile of a Cool Core of Galaxy Clusters
Naomi Ota, Kiyokazu Onzuka, Kuniaki Masai
The density profile of a cool core of intracluster gas is investigated for a cluster of galaxies that is initially in the virial equilibrium state, and then undergoes radiative coo…
X-ray Spectroscopy of Clusters of Galaxies
Naomi Ota
Clusters of galaxies are the most massive objects in the Universe and precise knowledge of their mass structure is important to understand the history of structure formation and co…
The Impact of Suzaku Measurements on Astroparticle Physics
Naomi Ota
Results from the Suzaku X-ray broad-band observations of clusters of galaxies are summarized. Aiming at understanding the physics of gas heating/particle acceleration and the clust…
The Hidden Fortress: Structure and substructure of the complex strong lensing cluster SDSS J1029+2623
Masamune Oguri, Tim Schrabback, Eric Jullo +8
We present Hubble Space Telescope (HST) ACS and WFC3 observations of SDSS J1029+2623, a three-image quasar lens system produced by a foreground cluster at z=0.584. Our strong lensi…
Suzaku observations of the Hydra A cluster out to the virial radius
Takuya Sato, Toru Sasaki, Kyoko Matsushita +12
We report Suzaku observations of the northern half of the Hydra A cluster out to ~1.4 Mpc, reaching the virial radius. This is the first Suzaku observations of a medium-size (kT ~3…
The Chandra view of the Largest Quasar Lens SDSS J1029+2623
Naomi Ota, Masamune Oguri, Xinyu Dai +6
We present results from Chandra observations of the cluster lens SDSS J1029+2623 at z_l=0.58, which is a gravitationally lensed quasar with the largest known image separation. We c…
