"Suprime33, Suprime-Cam weak lensing survey"
Takashi Hamana (JSPS fellow, IAP/NAOJ)
Suprime33 is weak lensing survey which exploits the unique capability of
Suprime-Cam. Its primary purpose is to construct, for the first time,
a mass selected cluster catalog containing more than 200 massive,
intermediate to high-z clusters.
I will present the following topics:
(1) a brief review of clusters of galaxies and their role in cosmology.
(2) an ability of weak lensing cluster surveys and properties of clusters
detected in weak lensing surveys. I will show that weak lensing survey
with Suprime-Cam provides an efficient way to search for clusters of galaxiess.
The expected number counts of weak lensing clusters is 7 per 1sq deg for
a high significant detection signal of S/N>4, which is comparable to a deep
X-ray selected cluster counts of 5 per 1sq deg for fx>2e-14erg/cm^2/s.
More importantly, weak lensing survey has the potential to detect massive
but X-ray faint clusters, which X-ray surveys have missed.
(3) results from a pilot survey in GTO 2sq deg field.
(4) the outline of Suprime33, its current status and preliminary results from
Seminars are also held at JAC,
