nbodykit: an open-source, massively parallel toolkit for large-scale structure
Nick Hand, Yu Feng, Florian Beutler +4
We present nbodykit, an open-source, massively parallel Python toolkit for analyzing large-scale structure (LSS) data. Using Python bindings of the Message Passing Interface (MPI),…
Developing the 3-Point Correlation Function For the Turbulent Interstellar Medium
Stephen K. N. Portillo, Zachary Slepian, Blakesley Burkhart +2
We present the first application of the angle-dependent 3-Point Correlation Function (3PCF) to the density fields magnetohydrodynamic (MHD) turbulence simulations intended to model…
Too hot to handle? Analytic solutions for massive neutrino or warm dark matter cosmologies
Zachary Slepian, Stephen KN Portillo
We obtain novel closed form solutions to the Friedmann equation for cosmological models containing a component whose equation of state is that of radiation at early times…
A Practical Computational Method for the Anisotropic Redshift-Space 3-Point Correlation Function
Zachary Slepian, Daniel J. Eisenstein
We present an algorithm enabling computation of the anisotropic redshift-space galaxy 3-point correlation function (3PCF) scaling as , with the number of galaxies. Our pre…
Galactos: Computing the Anisotropic 3-Point Correlation Function for 2 Billion Galaxies
Brian Friesen, Md. Mostofa Ali Patwary, Brian Austin +8
The nature of dark energy and the complete theory of gravity are two central questions currently facing cosmology. A vital tool for addressing them is the 3-point correlation funct…
An optimal FFT-based anisotropic power spectrum estimator
Nick Hand, Yin Li, Zachary Slepian +1
Measurements of line-of-sight dependent clustering via the galaxy power spectrum's multipole moments constitute a powerful tool for testing theoretical models in large-scale struct…
