LCDM halo substructure properties revealed with high resolution and large volume cosmological simulations
Ángeles Moliné, Miguel A. Sánchez-Conde, Alejandra Aguirre-Santaella +8
We investigate the structural properties, distribution and abundance of LCDM dark matter subhaloes using the Phi-4096 and Uchuu suite of N-body cosmological simulations. Thanks to…
The Uchuu Simulations: Data Release 1 and Dark Matter Halo Concentrations
Tomoaki Ishiyama, Francisco Prada, Anatoly A. Klypin +11
We introduce the Uchuu suite of large high-resolution cosmological -body simulations. The largest simulation, named Uchuu, consists of 2.1 trillion () dark matter parti…
Noise reduction for weak lensing mass mapping: An application of generative adversarial networks to Subaru Hyper Suprime-Cam first-year data
Masato Shirasaki, Kana Moriwaki, Taira Oogi +3
We propose a deep-learning approach based on generative adversarial networks (GANs) to reduce noise in weak lensing mass maps under realistic conditions. We apply image-to-image tr…
Dark Quest. I. Fast and Accurate Emulation of Halo Clustering Statistics and Its Application to Galaxy Clustering
Takahiro Nishimichi, Masahiro Takada, Ryuichi Takahashi +8
We perform an ensemble of -body simulations with particles for 101 flat CDM cosmological models sampled based on a maximin-distance Sliced Latin Hypercube Design. By…
First results on the cluster galaxy population from the Subaru Hyper Suprime-Cam survey. II. Faint end color-magnitude diagrams and radial profiles of red and blue galaxies at
Atsushi J. Nishizawa, Masamue Oguri, Taira Oogi +16
We present a statistical study of the redshift evolution of the cluster galaxy population over a wide redshift range from 0.1 to 1.1, using optically-selected CAMIRA cl…
The GC Simulations : Quantifying the Dark Side of the Universe in the Planck Cosmology
Tomoaki Ishiyama, Motohiro Enoki, Masakazu A. R. Kobayashi +3
We present the evolution of dark matter halos in six large cosmological N-body simulations, called the GC (New Numerical Galaxy Catalog) simulations on the basis of the LCDM c…
Detection of an ultra-bright submillimeter galaxy behind the Small Magellanic Cloud
Tatsuya Takekoshi, Yoichi Tamura, Tetsuhiro Minamidani +21
We report the discovery of a new ultra-bright submillimeter galaxy (SMG) behind the Small Magellanic Cloud (SMC). This SMG is detected as a 43.3+-8.4 mJy point source (MM J01071-73…
