Non-Linearity-Free prediction of the growth-rate $f σ_{8}$ using Convolutional Neural Networks

Koya Murakami, Indira Ocampo, Savvas Nesseris +2

The growth-rate $f σ_{8} (z)$ of the large-scale structure of the Universe is an important dynamic probe of gravity that can be used to test for deviations from General Relativity. How…

Impact of astrophysical effects on the dark matter mass constraint with 21cm intensity mapping

Koya Murakami, Atsushi J. Nishizawa, Kentaro Nagamine +1

We present an innovative approach to constraining the non-cold dark matter model using a convolutional neural network (CNN). We perform a suite of hydrodynamic simulations with var…
