Systematic analysis of Parity-Violating modes
Hong-Ming Zhu, Ue-Li Pen
Recent reports of cosmological parity violation in the 4PCF raises the question of how such violations could be systematically generated. Here we present a constructive procedure t…
Cosmic tidal reconstruction in redshift space
Shi-Hui Zang, Hong-Ming Zhu, Marcel Schmittfull +1
The gravitational coupling between large- and small-scale density perturbations leads to anisotropic distortions to the local small-scale matter fluctuations. Such local anisotropi…
Galaxy Spin Classification I: Z-wise vs S-wise Spirals With Chirality Equivariant Residual Network
He Jia, Hong-Ming Zhu, Ue-Li Pen
The angular momentum of galaxies (galaxy spin) contains rich information about the initial condition of the Universe, yet it is challenging to efficiently measure the spin directio…
Extracting high-order cosmological information in galaxy surveys with power spectra
Yuting Wang, Gong-Bo Zhao, Kazuya Koyama +11
The reconstruction method was proposed more than a decade ago to boost the signal of baryonic acoustic oscillations measured in galaxy redshift surveys, which is one of key probes…
Cosmic Tidal Reconstruction with Halo Fields
Hong-Ming Zhu, Tian-Xiang Mao, Ue-Li Pen
The gravitational coupling between large-scale perturbations and small-scale perturbations leads to anisotropic distortions of the small-scale matter distribution. The measured loc…
Nonlinear reconstruction of features in the primordial power spectrum from large-scale structure
Yuhao Li, Hong-Ming Zhu, Baojiu Li
Potential features in the primordial power spectrum have been searched for in galaxy surveys in recent years since these features can assist in understanding the nature of inflatio…
