X-Ray Spectral Variability of the Seyfert Galaxy NGC 4051 Observed with Suzaku
Y. Terashima, L. C. Gallo, H. Inoue +13
We report results from a Suzaku observation of the narrow-line Seyfert 1 NGC 4051. During our observation, large amplitude rapid variability is seen and the averaged 2--10 keV flux…
Suzaku observations of metallicity distribution in the intracluster medium of the NGC 5044 group
Madoka Komiyama, Kosuke Sato, Ryo Nagino +2
The metallicity distribution in the intracluster medium of the NGC 5044 group was studied up to 0.3 r_180 using the XIS instrument on board the Suzaku satellite. Abundances of O, M…
Temperature and Metallicity in the Intra-cluster Medium of ABELL 262 observed with Suzaku
Kosuke Sato, Kyoko Matsushita, Fabio Gastaldello
We studied the temperature and abundance distributions of intra-cluster medium (ICM) in the Abell 262 cluster of galaxies observed with Suzaku. Abell 262 is a bright, nearby poor c…
Charm quark system in 2+1 flavor lattice QCD using the PACS-CS configurations
CS Collaboration, Y. Namekawa, S. Aoki +12
We study heavy-heavy and heavy-light quark systems for charm with a relativistic heavy quark action in 2+1 flavor lattice QCD. Configurations are generated by the PACS-CS Collabora…
2+1 flavor lattice QCD simulation with -improved Wilson quarks
CS Collaboration, N. Ukita, S. Aoki +12
We present simulation details and results for the light hadron spectrum in N f = 2 + 1 lattice QCD with the nonperturbatively O(a)-improved Wilson quark action and the Iwasaki gaug…
SU(2) and SU(3) chiral perturbation theory analyses on meson and baryon masses in 2+1 flavor lattice QCD
CS Collaboration, D. Kadoh, S. Aoki +12
We investigate the quark mass dependence of meson and baryon masses obtained from 2+1 flavor dynamical quark simulations performed by the PACS-CS Collaboration. With the use of SU(…
