Radial profile and log-normal fluctuations of intra-cluster medium as an origin of systematic bias of spectroscopic temperature
Hajime Kawahara, Yasushi Suto, Tetsu Kitayama +4
The origin of the recently reported systematic bias in the spectroscopic temperature of galaxy clusters is investigated using cosmological hydrodynamical simulations. We find that…

Systematic bias in the estimate of cluster mass and the fluctuation amplitude from cluster abundance statistics
Mamoru Shimizu, Tetsu Kitayama, Shin Sasaki +1
We revisit the estimate of the mass fluctuation amplitude, sigma_8, from the observational X-ray cluster abundance. In particular, we examine the effect of the systematic differenc…
