Constraining the relative velocity effect using the Baryon Oscillation Spectroscopic Survey
Florian Beutler, Uros Seljak, Zvonimir Vlah
We analyse the power spectrum of the Baryon Oscillation Spectroscopic Survey (BOSS), Data Release 12 (DR12) to constrain the relative velocity effect, which represents a potential…
On Observables in a Dark Matter-Clustering Quintessence System
Matteo Fasiello, Zvonimir Vlah
We consider a system where dark matter dynamics is enriched by the presence of clustering quintessence in the approximation where the system is effectively reduced to one degree of…
FFT-PT: Reducing the two-loop large-scale structure power spectrum to low-dimensional radial integrals
Marcel Schmittfull, Zvonimir Vlah
Modeling the large-scale structure of the universe on nonlinear scales has the potential to substantially increase the science return of upcoming surveys by increasing the number o…
Very Massive Tracers and Higher Derivative Biases
Tomohiro Fujita, Valentin Mauerhofer, Leonardo Senatore +2
Most of the upcoming cosmological information will come from analyzing the clustering of the Large Scale Structures (LSS) of the universe through LSS or CMB observations. It is the…
The Gaussian streaming model and Lagrangian effective field theory
Zvonimir Vlah, Emanuele Castorina, Martin White
We update the ingredients of the Gaussian streaming model (GSM) for the redshift-space clustering of biased tracers using the techniques of Lagrangian perturbation theory, effectiv…
Perturbative approach to covariance matrix of the matter power spectrum
Irshad Mohammed, Uros Seljak, Zvonimir Vlah
We evaluate the covariance matrix of the matter power spectrum using perturbation theory up to dominant terms at 1-loop order and compare it to numerical simulations. We decompose…
Massive neutrinos in nonlinear large scale structure: A consistent perturbation theory
Michele Levi, Zvonimir Vlah
A consistent formulation to incorporate massive neutrinos in the perturbation theory of the effective CDM+baryons fluid is introduced. In this formulation all linear k dependence i…
Non-linear Fields in Generalized Cosmologies
Matteo Fasiello, Zvonimir Vlah
The perturbative approach to structure formation has recently received a lot of attention in the literature. In such setups the final predictions for observables like the power spe…
Fast Large Scale Structure Perturbation Theory using 1D FFTs
Marcel Schmittfull, Zvonimir Vlah, Patrick McDonald
The usual fluid equations describing the large-scale evolution of mass density in the universe can be written as local in the density, velocity divergence, and velocity potential f…
