A General Study of the Influence of Catastrophic Photometric Redshift Errors on Cosmology with Cosmic Shear Tomography

Andrew P. Hearin, Andrew R. Zentner, Zhaoming Ma +1

A goal of forthcoming imaging surveys is to use weak gravitational lensing shear measurements to constrain dark energy. We quantify the importance of uncalibrated photometric redsh…

Size of spectroscopic calibration samples for cosmic shear photometric redshifts

Zhaoming Ma, Gary Bernstein

Weak gravitational lensing surveys using photometric redshifts can have their cosmological constraints severely degraded by errors in the photo-z scale. We explore the cosmological…

The nonlinear matter power spectrum

Zhaoming Ma

We modify the public PM code developed by Anatoly Klypin and Jon Holtzman to simulate cosmology with arbitrary initial power spectrum and equation of state of dark energy. With thi…
