Cosmology with galaxy cluster weak lensing: statistical limits and experimental design

no code implementations3 Dec 2020 Hao-Yi Wu, David H. Weinberg, Andrés N. Salcedo, Benjamin D. Wibking

A one-month observing program with Roman Space Telescope targeting approximately 2500 massive clusters could achieve a 0. 5% constraint on sigma_8(z=0. 7) on its own, or a ~0. 33% constraint in combination with the HLS.

We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset.

The Rockstar Phase-Space Temporal Halo Finder and the Velocity Offsets of Cluster Cores

4 code implementations19 Oct 2011 Peter S. Behroozi, Risa H. Wechsler, Hao-Yi Wu

We present a new algorithm for identifying dark matter halos, substructure, and tidal features.

Gravitationally Consistent Halo Catalogs and Merger Trees for Precision Cosmology

2 code implementations19 Oct 2011 Peter S. Behroozi, Risa H. Wechsler, Hao-Yi Wu, Michael T. Busha, Anatoly A. Klypin, Joel R. Primack

We find that both the ROCKSTAR and BDM halo finders track halos extremely well; in both, the number of halos which do not have physically consistent progenitors is at the 1-2% level across all halo masses.
