(DarkAI) Mapping the large-scale density field of dark matter using artificial intelligence
Zitong Wang, Feng Shi, Xiaohu Yang +3
Herein, we present a deep-learning technique for reconstructing the dark-matter density field from the redshift-space distribution of dark-matter halos. We built a UNet-architectur…
HIR4: Cosmological signatures imprinted on the cross correlation between 21-cm map and galaxy clustering
Feng Shi, Yong-Seon Song, Jacobo Asorey +5
We explore the cosmological multitracer synergies between an emission line galaxy distribution from the Dark Energy Spectroscopic Instrument and a Tianlai Project 21-cm intensity m…
HIR4: cosmology from a simulated neutral hydrogen full sky using Horizon Run 4
Jacobo Asorey, David Parkinson, Feng Shi +6
The distribution of cosmological neutral hydrogen will provide a new window into the large-scale structure of the Universe with the next generation of radio telescopes and surveys.…
The Next Generation of Cosmological Measurements with Type Ia Supernovae
Dan Scolnic, Saul Perlmutter, Greg Aldering +56
While Type Ia Supernovae (SNe Ia) are one of the most mature cosmological probes, the next era promises to be extremely exciting in the number of different ways SNe Ia are used to…
Galaxy-galaxy weak-lensing measurement from SDSS: II. host halo properties of galaxy groups
Wentao Luo, Xiaohu Yang, Tianhuan Lu +10
As the second paper of a series on studying galaxy-galaxy lensing signals using the Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we present our measurement and modelling of…
