Approximating the peculiar velocity distribution of dark matter halos with Tsallis statistics
Jun Pan, Ming Li
Dark matter halos, which host galaxies and galaxy clusters, have peculiar velocities far from thermal equilibrium. Characterizing the nonlinear and non-Gaussian features of this ve…
Halo Mass of ULIRGs at Cosmic Noon
Jun Pan, Ming Li, Cheng Cheng +1
We present a clustering analysis of ultraluminous infrared galaxies (ULIRGs) at , uniformly selected by flux and IRAC colors in the COSMOS and BOO…
Pair Counting without Binning -- A New Approach to Correlation Functions in Clustering Statistics
Shiyu Yue, Longlong Feng, Wenjie Ju +6
This paper presents a novel perspective on correlation functions in the clustering analysis of the large-scale structure of the universe. We first recognise that pair counting in b…
Numerical investigation of non-Gaussianities in the phase and modulus of density Fourier modes
Jian Qin, Jun Pan, Yu Yu +1
We numerically investigate non-Gaussianities in the late-time cosmological density field in Fourier space. We explore various statistics, including the two-point and three-point pr…
About One-point Statistics of the Ratio of Two Fourier-transformed Cosmic Fields and an Application
Ming Li, Jun Pan, Pengjie Zhang +7
The Fourier transformation is an effective and efficient operation of Gaussianization at the one-point level. Using a set of N-body simulation data, we verified that the one-point…
Estimating power spectrum of discrete cosmic momentum field with fast Fourier transform
Jun Pan
Fast Fourier transform based estimators are formulated for measuring momentum power spectra, including the auto power spectra of the momentum, the momentum divergence, and the cros…
