Extract the fraction distribution of ddm particles as a function of halo mass
Free streaming length of DDM
To calculate the halo model of ddm to get the non-linear power spectrum
Analyze AHF and Gadget outputs of halos
This code can calculate the empirical velocity function of CDM, WDM and DDM. The observed data comes from Klypin’s paper on the local HI survey.
Generate smaller samples of Jing's simulation
The extended Gadget2 with the particle update algorithm of solving the structure formation of decaying dark matter.
Calculate gadget file power spectrum with FFT and OpenMP
The dimenssionless growth rate of a flat universe
This is corrected version of POM for Hadoop definitive guide 4th edition Chapter 6, where the original POM does not work with mrunit.
Fitting the halo density profile with the generalized NFW form.
The code combines the AHF outputs and an adaptive algorithm to determine a consistent isodensity regions and fits the triaxial shape of the halos.
Modeling the halo shape parameters distribution with the Zeldovich approximation. A generalization of including the local type non-Gaussianity is also considered.
A realization of 2 dimensional interpolation using spline functions.
Deep Learning library for Python. Convnets, recurrent neural networks, and more. Runs on TensorFlow or Theano.
A quick tool to calculate the linear power spectrum of a given cosmology.
Local Type non-Gaussianity Initial Condition (LTic) generator. This produces the IC for N-body simulation with possible local type Fnl. Parallelization through OpenMP is utilized.
A handy tool to calculate the theoretical mass function of cold dark matter cosmology. Different models of f(v) can be easily extended based on the code.
Convertor of the NCDC data to mini tab format as required by the Pig or Hive query
Minimize Eq.(4) of Angulo and White (2009) to obtain the best length scaling relation and redshift mapping between two simulations.
Models built with TensorFlow
To find a relation between the neff and the correction of the RSD window function
The code computes the density power spectrum and the velocity field power spectrum to obtain the window function of the redshift space distortion. The search grid algorithm is utilized to determine the velocity field on grids. The code implements OpenMP to accelerate the computing.
Pretty handy shell tools: (1) find files in local dir (2) count the lines of all files of common suffix (3) delete files except certain ones.
Density field is computed with the NP method. A slice of the simulation output is used to generate the picture.
The Lagrange masks of the halos of the final output are computed combining the information of the initial condition.
