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),…
Extending the modeling of the anisotropic galaxy power spectrum to
Nick Hand, Uros Seljak, Florian Beutler +1
We present a new model for the redshift-space power spectrum of galaxies and demonstrate its accuracy in modeling the monopole, quadrupole, and hexadecapole of the galaxy density f…
The clustering of the SDSS-IV extended Baryon Oscillation Spectroscopic Survey DR14 quasar sample: First measurement of Baryon Acoustic Oscillations between redshift 0.8 and 2.2
Metin Ata, Falk Baumgarten, Julian Bautista +60
We present measurements of the Baryon Acoustic Oscillation (BAO) scale in redshift-space using the clustering of quasars. We consider a sample of 147,000 quasars from the extended…
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…
