swPHoToNs: Toward trillion‐body‐scale cosmological N‐body simulations on Sunway TaihuLight supercomputer

Engineering Reports, Volume 7, Issue 3, March 2025.
We present the details of implementing a highly efficient and scalable Cosmological N‐body simulation framework on the heterogeneous many‐core supercomputer Sunway TaihuLight. We manage to conduct cosmological simulations which contain up to 1.6 trillion particles, obtaining a sustained performance of 56.3 PFlops with a weak‐scaling parallel efficiency

Galaxies and large scale structure at high redshifts [PDF]

Proceedings of the National Academy of Sciences, 1998
It is now straightforward to assemble large samples of very high redshift ( z ∼ 3) field galaxies selected by their pronounced spectral discontinuity at the rest frame Lyman limit of hydrogen (at 912 Å).

Clustering of galaxies at high redshifts [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
Recent observations show a large concentration of galaxies at high redshift. At first sight, strong clustering of galaxies at high redshifts seems to be in contradiction with the models of structure formation. In this paper we show that such structures are a manifestation of the strong clustering of rare peaks in the density field.

Cosmic Magnification of High-Redshift Submillimeter Galaxies

Galaxies
Weak lensing magnification probes the correlation between galaxies and the underlying matter field in a similar fashion to galaxy–galaxy lensing shear. Although it has long been sidelined in favor of the latter on the grounds of poorer performance in terms of statistical significance, the provision of a large sample of high-redshift submillimeter ...
