A Gravitationally Lensed Quasar with Quadruple Images Separated by 14.62 Arcseconds (2003)
Inada, N., Oguri, M., Pindor, B., Hennawi, J. F., Chiu, K., Zheng, W., ...
Gravitational lensing is a powerful tool for the study of the distribution of dark matter in the Universe. The cold-dark-matter model of the formation of large-scale structures predicts the existence...
Oguri, M., Inada, N., Keeton, C. R., Pindor, B., Hennawi, J. F., Gregg, M. D., ...
We study the recently discovered gravitational lens SDSS J1004+4112, the first quasar lensed by a cluster of galaxies. It consists of four images with a maximum separation of 14.62''. The system has...
Kitayama, T., Komatsu, E., Ota, N., Kuwabara, T., Suto, Y., Yoshikawa, K., ...
Foreseeing the era of high spatial resolution measurements of the Sunyaev-Zel'dovich effect (SZE) in clusters of galaxies, we present a prototype analysis of this sort combined with Chandra X-ray...
Jing, Y. P., Börner, G., Suto, Y.
We report on the measurement of the two-point correlation function and the pairwise peculiar velocity of galaxies in the IRAS Point Source Catalog Redshift (PSCz) Survey. We compute these statistics...
Hamana, T., Yoshida, N., Suto, Y.
We critically examine the reliability of the dark matter clustering in high-resolution cosmological N-body simulations on scales below the mean separation length of particles. The particle...
Triaxial modeling of halo density profiles with high-resolution N-body simulations (2002)

Hamana, T, Yoshida, N, Suto, Y, Evrard, AE
We develop a phenomenological model to predict the clustering of dark matter halos on the light cone by combining several existing theoretical models. Assuming that the velocity field of halos on...
Taruya, A., Magira, H., Jing, Y. P., Suto, Y.
We quantify the degree of nonlinearity and stochasticity of the clustering of biased objects, using cosmological N-body simulations. Adopting the peaks and the halos as representative biasing models,...
Melott, A. L., Shandarin, S. F., Splinter, R. J., Suto, Y.
Two-body scattering and other discreteness effects are unimportant in cosmological gravitational clustering in most scenarios, since the dark matter has a small particle mass. The collective field...
We present a method to compute the probability distribution function of the (true) Hubble constant and the age of the universe, given the estimate of the Hubble constant in our nearby galaxy samples....

Suto, Y., Suginohara, T., Inagaki, Y.
While the recent discovery of the Cepheid variables in the Virgo cluster galaxies puts additional support for the Hubble constant $H_0 \sim 80$km/sec/Mpc, a relatively lower value $H_0 \sim...
