Searching for massive clusters in weak lensing surveys
Takashi Hamana, Masahiro Takada, Naoki Yoshida
We explore the ability of weak lensing surveys to locate massive clusters. We use both analytic models of dark matter halos and mock weak lensing surveys generated from a large cos…
Properties of host haloes of Lyman-break galaxies and Lyman-alpha Emitters from their number densities and angular clustering
Takashi Hamana, Masami Ouchi, Kazuhiro Shimasaku +2
We explore empirical relations between three different populations of high-redshift galaxies and their hosting dark halos employing the halo model approach. Specifically we conside…
Modeling peculiar velocities of dark matter halos
Takashi Hamana, Issha Kayo, Naoki Yoshida +2
We present a simple model that accurately describes various statistical properties of peculiar velocities of dark matter halos. We pay particular attention to the following two eff…
