Scale-dependent bias and bispectrum in neutrino separate universe simulations
Chi-Ting Chiang, Wayne Hu, Yin Li +1
Cosmic background neutrinos have a large velocity dispersion, which causes the evolution of long-wavelength density perturbations to depend on scale. This scale-dependent growth le…
The Lyman- power spectrum - CMB lensing convergence cross-correlation
Chi-Ting Chiang, Anže Slosar
We investigate the three-point correlation between the Lyman- forest and the CMB weak lensing () expressed as the cross-correlation between the CMB weak lensing field…
Generating Log-normal Mock Catalog of Galaxies in Redshift Space
Aniket Agrawal, Ryu Makiya, Chi-Ting Chiang +3
We present a public code to generate a mock galaxy catalog in redshift space assuming a log-normal probability density function (PDF) of galaxy and matter density fields. We draw g…
Response approach to the squeezed-limit bispectrum: application to the correlation of quasar and Lyman- forest power spectrum
Chi-Ting Chiang, Agnieszka M. Cieplak, Fabian Schmidt +1
The squeezed-limit bispectrum, which is generated by nonlinear gravitational evolution as well as inflationary physics, measures the correlation of three wavenumbers, in the config…
The halo squeezed-limit bispectrum with primordial non-Gaussianity: a power spectrum response approach
Chi-Ting Chiang
Modeling the nonlinearity of the halo bispectrum remains a major challenge in modern cosmology, in particular for ongoing and upcoming large-scale structure observations that are p…
