Lyman-α polarization from cosmological ionization fronts: I. Radiative transfer simulations
Yuanyuan Yang, Emily Koivu, Chenxiao Zeng +2
In this paper, we present the formalism of simulating Lyman- emission and polarization around reionization ( = 8) from a plane-parallel ionization front. We accomplish this b…
Self-calibrating optical galaxy cluster selection bias using cluster, galaxy, and shear cross-correlations
Chenxiao Zeng, Andrés N. Salcedo, Hao-Yi Wu +1
The clustering signals of galaxy clusters are known to be powerful tools for self-calibrating the mass-observable relation and are complementary to cluster abundance and lensing. I…
Optical selection bias and projection effects in stacked galaxy cluster weak lensing
Hao-Yi Wu, Matteo Costanzi, Chun-Hao To +16
Cosmological constraints from current and upcoming galaxy cluster surveys are limited by the accuracy of cluster mass calibration. In particular, optically identified galaxy cluste…
Non-equilibrium temperature evolution of ionization fronts during the Epoch of Reionization
Chenxiao Zeng, Christopher M. Hirata
The epoch of reionization (EoR) marks the end of the Cosmic Dawn and the beginning of large-scale structure formation in the universe. The impulsive ionization fronts (I-fronts) he…
Searching for Oscillations in the Primordial Power Spectrum with CMB and LSS Data
Chenxiao Zeng, Ely D. Kovetz, Xuelei Chen +3
Different inflationary models predict oscillatory features in the primordial power spectrum. These can leave an imprint on both the cosmic microwave background (CMB) and the large-…
