Covariance of the One-Dimensional Mass Power Spectrum
Hu Zhan, Daniel Eisenstein
We analyse the covariance of the one-dimensional mass power spectrum along lines of sight. The covariance reveals the correlation between different modes of fluctuations in the cos…
Effect of Hot Baryons on the Weak-Lensing Shear Power Spectrum
Hu Zhan, Lloyd Knox
We investigate the impact of the intracluster medium on the weak-lensing shear power spectrum (PS). Using a halo model we find that, compared to the dark matter only case, baryonic…
The Large-Scale Structure of the Universe in One Dimension
Hu Zhan
(Abridged) I investigate statistical properties of one-dimensional fields in the universe such as the Lyman alpha forest and inverted line-of-sight densities. Because of gravitatio…
Extrapolation Method for the No-Core Shell Model
H. Zhan, A. Nogga, B. R. Barrett +2
Nuclear many-body calculations are computationally demanding. An estimate of their accuracy is often hampered by the limited amount of computational resources even on present-day s…
