Future Japanese missions for the study of warm-hot intergalactic medium
T. Ohashi, M. Ishida, S. Sasaki +10
We present our proposal for a small X-ray mission DIOS (Diffuse Intergalactic Oxygen Surveyor) to perform survey observations of warm-hot intergalactic medium using OVII and OVIII…
Searching for cosmic missing baryons with DIOS -- Diffuse Intergalactic Oxygen Surveyor --
Yasushi Suto, Kohji Yoshikawa, Noriko Y. Yamasaki +9
Approximately 30 to 50 percent of the total baryons in the present universe is supposed to take a form of warm/hot intergalactic medium (WHIM) whose X-ray continuum emission is ver…
High-resolution numerical simulations for galaxy formation
Y. P. Jing, Yasushi Suto
Understanding of the structure evolution in the Universe has been greatly advanced with a rapid progress in high-resolution cosmological simulations. In this contribution, we repor…
Slow relative motion of IRAS galaxies at small separations: implications for galaxy formation models
Y. P. Jing, G. Boerner, Yasushi Suto
We report on the measurement of the two-point correlation function and the pairwise peculiar velocity of galaxies in the IRAS PSCz survey. The real space two-point correlation func…
Clustering of Dark Matter Halos on the Light-cone
Yasushi Suto
A phenomenological model for the clustering of dark matter halos on the light-cone is presented. In particular, an empirical prescription for the scale-, mass-, and time-dependence…
The Universe Traced by Clusters
Yasushi Suto
I critically review a methodology of using clusters of galaxies as cosmological probes. The understanding of the abundances and spatial correlations of dark matter halos has been s…
