: Halo Model Emulator for the Galaxy Power Spectrum
Jamie Donald-McCann, Florian Beutler, Kazuya Koyama +1
We present , a suite of neural network based emulators and accompanying Python package that have been developed with the goal of producing fast and accurate pr…
hankl: A lightweight Python implementation of the FFTLog algorithm for Cosmology
Minas Karamanis, Florian Beutler
We introduce hankl, a lightweight Python implementation of the FFTLog algorithm for Cosmology. The FFTLog algorithm is an extension of the Fast Fourier Transform (FFT) for logarith…
Unified galaxy power spectrum measurements from 6dFGS, BOSS, and eBOSS
Florian Beutler, Patrick McDonald
We make use of recent developments in the analysis of galaxy redshift surveys to present an easy to use matrix-based analysis framework for the galaxy power spectrum multipoles, in…
Iterative reconstruction excursions for Baryon Acoustic Oscillations and beyond
Hee-Jong Seo, Atsuhisa Ota, Marcel Schmittfull +2
The density field reconstruction technique has been widely used for recovering the Baryon Acoustic Oscillation (BAO) feature in galaxy surveys that has been degraded due to nonline…
Modeling iterative reconstruction and displacement field in the large scale structure
Atsuhisa Ota, Hee-Jong Seo, Shun Saito +1
The next generation of galaxy surveys like the Dark Energy Spectroscopic Instrument (DESI) and Euclid will provide datasets orders of magnitude larger than anything available to da…
The clustering of the SDSS-IV extended Baryon Oscillation Spectroscopic Survey quasar sample: Testing observational systematics on the Baryon Acoustic Oscillation measurement
Grant Merz, Mehdi Rezaie, Hee-Jong Seo +15
Baryon Acoustic Oscillations are considered to be a very robust standard ruler against various systematics. This premise has been tested against observational systematics, but not…
