The clustering of galaxies in the completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Primordial non-Gaussianity in Fourier Space
Eva-Maria Mueller, Mehdi Rezaie, Will J. Percival +12
We present measurements of the local primordial non-Gaussianity parameter \fNLloc from the clustering of 343,708 quasars with redshifts 0.8 < z < 2.2 distributed over 4808 square d…
Primordial non-Gaussianity from the Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey I: Catalogue Preparation and Systematic Mitigation
Mehdi Rezaie, Ashley J. Ross, Hee-Jong Seo +17
We investigate the large-scale clustering of the final spectroscopic sample of quasars from the recently completed extended Baryon Oscillation Spectroscopic Survey (eBOSS). The sam…
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…
The growth of density perturbations in the last 10 billion years from tomographic large-scale structure data
Carlos García-García, Jaime Ruiz Zapatero, David Alonso +5
In order to investigate the origin of the ongoing tension between the amplitude of matter fluctuations measured by weak lensing experiments at low redshifts and the value inferred…
HI constraints from the cross-correlation of eBOSS galaxies and Green Bank Telescope intensity maps
Laura Wolz, Alkistis Pourtsidou, Kiyoshi W. Masui +18
We present the joint analysis of Neutral Hydrogen (HI) Intensity Mapping observations with three galaxy samples: the Luminous Red Galaxy (LRG) and Emission Line Galaxy (ELG) sample…
