Toward an accurate Dark Matter power spectrum beyond BAO scales
Naonori S. Sugiyama, Toshifumi Futamase
We propose a new approximated expression for non-linear Dark Matter power spectrum much beyond BAO scales. The proposed expression agrees with the result of N-body simulation with…
An Application of Wiener Hermite Expansion to Non-linear Evolution of Dark Matter
Naonori S. Sugiyama, Toshifumi Futamase
We apply the Wiener Hermite (WH) expansion to the non-linear evolution of Large-Scale Structure, and obtain an approximate expression for the matter power spectrum in full order of…
New solutions of charged regular black holes and their stability
Nami Uchikata, Shijun Yoshida, Toshifumi Futamase
We construct new regular black hole solutions by matching the de Sitter solution and the Reissner-Nordstrom solution with a timelike thin shell. The thin shell is assumed to have m…
Elliptical Weighted HOLICs for Weak Lensing Shear Measurement part3:Random Count Noise Effect for Image's Moments in Weak Lensing Analysis
Yuki Okura, Toshifumi Futamase
This is the third paper on the improvements of systematic errors in our weak lensing analysis using an elliptical weight function, called E-HOLICs. In the previous papers we have s…
δN formalism
Naonori S. Sugiyama, Eiichiro Komatsu, Toshifumi Futamase
Precise understanding of nonlinear evolution of cosmological perturbations during inflation is necessary for the correct interpretation of measurements of non-Gaussian correlations…
A Systematic Review of Strong Gravitational Lens Modeling Software
Alan T. Lefor, Toshifumi Futamase, Mohammad Akhlaghi
Despite expanding research activity in gravitational lens modeling, there is no particular software which is considered a standard. Much of the gravitational lens modeling software…
