The velocity field of baryonic gas in the universe
Bryan Kim, Ping He, Jesús Pando +2
The dynamic evolution of the baryonic intergalactic medium (IGM) caused by the underlying dark matter gravity is governed by the Navier-Stokes equations in which many cooling and h…
The Statistical Discrepancy between the IGM and Dark Matter Fields: One-Point Statistics
Jesús Pando, Long-Long Feng, Li-Zhi Fang
We investigate the relationship between the mass and velocity fields of the intergalactic medium (IGM) and dark matter. Although the evolution of the IGM is dynamically governed by…
Intermittent Features of the QSO Ly Transmitted Flux: Results from Hydrodynamic Cosmological Simulations
Long-Long Feng, Jesus Pando, Li-Zhi Fang
It has been recently found that the local fluctuations of the QSO's Ly absorption spectrum transmitted flux show spiky structures. This implies that the mass fields of the inter…
Non-Gaussian Features of Transmitted Flux of QSO's Ly Absorption: Intermittent Exponent
Jesus Pando, Long-Long Feng, Priya Jamkhedkar +4
We calculate the structure function and intermittent exponent of the 1.) Keck data, which consists of 29 high resolution, high signal to noise ratio (S/N) QSO Ly absorption spec…
The intermittent behavior and hierarchical clustering of the cosmic mass field
Long-Long Feng, Jesus Pando, Li-Zhi Fang
The hierarchical clustering model of the cosmic mass field is examined in the context of intermittency. We show that the mass field satisfying the correlation hierarchy $ξ_n\simeq…
Quasi-local evolution of cosmic gravitational clustering in the weakly non-linear regime
J. Pando, L. Feng, L. Z. Fang
We investigate the weakly non-linear evolution of cosmic gravitational clustering in phase space by looking at the Zel'dovich solution in the discrete wavelet transform (DWT) repre…
