Cosmological Structure Formation in Decaying Dark Matter Models
Dalong Cheng, M. -C. Chu, Jiayu Tang
The standard cold dark matter (CDM) model predicts too many and too dense small structures. We consider an alternative model that the dark matter undergoes two-body decays with cos…
Angular momentum - mass relation for dark matter haloes
Shihong Liao, Dalong Cheng, M. -C. Chu +1
We study the empirical relation between an astronomical object's angular momentum and mass , , the relation, using N-body simulations. In particular, we invest…
Cosmic microwave background constraints on the tensor-to-scalar ratio
King Lau, Jiayu Tang, M. -C. Chu
One of the main goals of modern cosmic microwave background (CMB) missions is to measure the tensor-to-scalar ratio accurately to constrain inflation models. Due to ignorance a…
Likelihood reconstruction method of real-space density and velocity power spectra from a redshift galaxy survey
Jiayu Tang, Issha Kayo, Masahiro Takada
We develop a maximum likelihood based method of reconstructing band powers of the density and velocity power spectra at each wavenumber bins from the measured clustering features o…
