Forecasting the constraints on optical selection bias and projection effects of galaxy cluster lensing with multiwavelength data
Conghao Zhou, Hao-Yi Wu, Andrés N. Salcedo +12
Galaxy clusters identified with optical imaging tend to suffer from projection effects, which impact richness (the number of member galaxies in a cluster) and lensing coherently. P…
Dark Energy Survey Year 1 Clusters are Consistent with Planck
Andrés N. Salcedo, Hao-Yi Wu, Eduardo Rozo +4
The recent Dark Energy Survey Year 1 (DES-Y1) analysis of galaxy cluster abundances and weak lensing produced and constraints in 5.6 tension with Planck. It is…
Impact of Property Covariance on Cluster Weak lensing Scaling Relations
Zhuowen Zhang, Arya Farahi, Daisuke Nagai +5
We present an investigation into a hitherto unexplored systematic that affects the accuracy of galaxy cluster mass estimates with weak gravitational lensing. Specifically, we study…
Not empty enough: a local void cannot solve the tension
Dragan Huterer, Hao-Yi Wu
We review arguably the simplest solution for the Hubble tension -- the possibility that we live in a void. In this scenario, the local Hubble constant is higher than the glob…
