Removing Imaging Systematics from Galaxy Clustering Measurements with Obiwan : Application to the SDSS-IV extended Baryon Oscillation Spectroscopic Survey Emission Line Galaxy Sample
Hui Kong, Kaylan J. Burleigh, Ashley Ross +10
This work presents the application of a new tool, Obiwan , which uses image simulations to determine the selection function of a galaxy redshift survey and calculate 3-dimensional…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: exploring the Halo Occupation Distribution model for Emission Line Galaxies
Santiago Avila, Violeta Gonzalez-Perez, Faizan G. Mohammad +25
We study the modelling of the Halo Occupation Distribution (HOD) for the eBOSS DR16 Emission Line Galaxies (ELGs). Motivated by previous theoretical and observational studies, we c…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: a multi-tracer analysis in Fourier space for measuring the cosmic structure growth and expansion rate
Gong-Bo Zhao, Yuting Wang, Atsushi Taruya +23
We perform a joint BAO and RSD analysis using the eBOSS DR16 LRG and ELG samples in the redshift range of , and detect a RSD signal from the cross power spectrum at…
The clustering of the SDSS-IV extended Baryon Oscillation Spectroscopic Survey DR16 luminous red galaxy and emission line galaxy samples: cosmic distance and structure growth measurements using multiple tracers in configuration space
Yuting Wang, Gong-Bo Zhao, Cheng Zhao +25
We perform a multi-tracer analysis using the complete Sloan Digital Sky Survey IV (SDSS-IV) extended Baryon Oscillation Spectroscopic Survey (eBOSS) DR16 luminous red galaxy (LRG)…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: measurement of the BAO and growth rate of structure of the emission line galaxy sample from the anisotropic power spectrum between redshift 0.6 and 1.1
Arnaud de Mattia, Vanina Ruhlmann-Kleider, Anand Raichoor +33
We analyse the large-scale clustering in Fourier space of emission line galaxies (ELG) from the Data Release 16 of the Sloan Digital Sky Survey IV extended Baryon Oscillation Spect…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: N-body Mock Challenge for the eBOSS Emission Line Galaxy Sample
Shadab Alam, Arnaud de Mattia, Amélie Tamone +27
Cosmological growth can be measured in the redshift space clustering of galaxies targeted by spectroscopic surveys. Accurate prediction of clustering of galaxies will require under…
A tomographic map of the large-scale matter distribution using the eBOSS Stripe 82 Ly- forest
C. Ravoux, E. Armengaud, M. Walther +16
The Lyman- (hereafter Ly-) forest is a probe of large-scale matter density fluctuations at high redshift, . It consists of HI absorption spectra along individual lin…
A light neural network for modulation detection under impairments
Thomas Courtat, Hélion du Mas des Bourboux
We present a neural network architecture able to efficiently detect modulation scheme in a portion of I/Q signals. This network is lighter by up to two orders of magnitude than oth…
