Forecasts for warm dark matter from weakly lensed Type Ia supernovae
Mei Takeda, Ryuichiro Hada, Ken-ichi Oohara +1
We investigate the possibility to have a constraint on the mass of thermal warm dark matter (WDM) particle from the expected data of the Wide Field Infrared Survey Telescope (WFIRS…
Application of the iterative reconstruction to simulated galaxy fields
Ryuichiro Hada, Daniel J. Eisenstein
We apply an iterative reconstruction method to galaxy mocks in redshift space obtained from -body simulations. Comparing the two-point correlation functions for the reconstructe…
Forecasts of cosmological constraints from Type Ia supernovae including the weak-lensing convergence
Ryuichiro Hada, Toshifumi Futamase
We investigate how the cosmological constraints from SNe Ia are improved by including the effects of weak-lensing convergence. To do so, we introduce the lognormal function as the…
An iterative reconstruction of cosmological initial density fields
Ryuichiro Hada, Daniel J. Eisenstein
We present an iterative method to reconstruct the linear-theory initial conditions from the late-time cosmological matter density field, with the intent of improving the recovery o…
