Mitigating the impact of fiber assignment on clustering measurements from deep galaxy redshift surveys
Tomomi Sunayama, Masahiro Takada, Martin Reinecke +6
We examine the impact of fiber assignment on clustering measurements from fiber-fed spectroscopic galaxy surveys. We identify new effects which were absent in previous, relatively…
Perturbation theory approach to predict the covariance matrices of the galaxy power spectrum and bispectrum in redshift space
Naonori S. Sugiyama, Shun Saito, Florian Beutler +1
In this paper, we predict the covariance matrices of both the power spectrum and the bispectrum, including full non-Gaussian contributions, redshift space distortions, linear bias…
Radiative Transfer Distortions of Lyman- Emitters: a New Fingers-of-God Damping in the Clustering in Redshift Space
Chris Byrohl, Shun Saito, Christoph Behrens
Complex radiative transfer (RT) of the Lyman- photons poses a theoretical challenge to galaxy surveys which infer the large-scale structure with Lyman- emitters (LAEs). Guide…
Detecting Baryon Acoustic Oscillations in Dark Matter from Kinematic Weak Lensing Surveys
Zhejie Ding, Hee-Jong Seo, Eric Huff +2
We investigate the feasibility of extracting Baryon Acoustic Oscillations (BAO) from cosmic shear tomography. We particularly focus on the BAO scale precision that can be achieved…
