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),…
Theoretical Systematics of Future Baryon Acoustic Oscillation Surveys
Zhejie Ding, Hee-Jong Seo, Zvonimir Vlah +3
Future Baryon Acoustic Oscillation surveys aim at observing galaxy clustering over a wide range of redshift and galaxy populations at great precision, reaching tenths of a percent,…
The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment
Bela Abolfathi, D. S. Aguado, Gabriela Aguilar +344
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourtee…
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…
Imprints of Reionization in Galaxy Clustering
Fabian Schmidt, Florian Beutler
Reionization, the only phase transition in the Universe since recombination, is a key event in the cosmic history of baryonic matter. We derive, in the context of the large-scale b…
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…
