A Lagrangian theory for galaxy shape statistics
Shi-Fan Chen, Nickolas Kokron
We formulate the Lagrangian perturbation theory of galaxy intrinsic alignments and compute the resulting auto and cross power spectra of galaxy shapes, densities and matter to 1-lo…
Mitigating the noise of DESI mocks using analytic control variates
Boryana Hadzhiyska, Martin J. White, Xinyi Chen +30
In order to address fundamental questions related to the expansion history of the Universe and its primordial nature with the next generation of galaxy experiments, we need to mode…
Magnification Bias Estimators for Realistic Surveys: an Application to the BOSS Survey
Lukas Wenzl, Shi-Fan Chen, Rachel Bean
In addition to the intrinsic clustering of galaxies themselves, the spatial distribution of galaxies observed in surveys is modulated by the presence of weak lensing due to matter…
Aemulus : Precise Predictions for Matter and Biased Tracer Power Spectra in the Presence of Neutrinos
Joseph DeRose, Nickolas Kokron, Arka Banerjee +6
We present the Aemulus simulations: a suite of 150 -body simulations with a mass resolution of $3.51\times 10^{10} \frac{Ω_{cb}}{0.3} ~ h^{-1} M_{\o…
A comparison of template vs. direct model fitting for redshift-space distortions in BOSS
Mark Maus, Shi-Fan Chen, Martin White
The growth of large-scale structure, as revealed in the anisotropic of clustering of galaxies in the low redshift Universe, provides a stringent test of our cosmological model. The…
