Perturbation theory, effective field theory, and oscillations in the power spectrum
Zvonimir Vlah, Uroš Seljak, Man Yat Chu +1
We explore the relationship between the nonlinear matter power spectrum and the various Lagrangian and Standard Perturbation Theories (LPT and SPT). We first look at it in the cont…
A Lagrangian effective field theory
Zvonimir Vlah, Martin White, Alejandro Aviles
We have continued the development of Lagrangian, cosmological perturbation theory for the low-order correlators of the matter density field. We provide a new route to understanding…
Galaxy power spectrum in redshift space: combining perturbation theory with the halo model
Teppei Okumura, Nick Hand, Uros Seljak +2
Theoretical modeling of the redshift-space power spectrum of galaxies is crucially important to correctly extract cosmological information from redshift surveys. The task is compli…
Tidal alignment of galaxies
Jonathan Blazek, Zvonimir Vlah, Uroš Seljak
We develop an analytic model for galaxy intrinsic alignments (IA) based on the theory of tidal alignment. We calculate all relevant nonlinear corrections at one-loop order, includi…
On the Statistics of Biased Tracers in the Effective Field Theory of Large Scale Structures
Raul Angulo, Matteo Fasiello, Leonardo Senatore +1
With the completion of the Planck mission, in order to continue to gather cosmological information it has become crucial to understand the Large Scale Structures (LSS) of the unive…
Halo Zeldovich model and perturbation theory: dark matter power spectrum and correlation function
Uroš Seljak, Zvonimir Vlah
Perturbation theory for dark matter clustering has received a lot of attention in recent years, but its convergence properties remain poorly justified and there is no successful mo…
