Linear response to long wavelength fluctuations using curvature simulations
Tobias Baldauf, Uroš Seljak, Leonardo Senatore +1
We study the local response to long wavelength fluctuations in cosmological -body simulations, focusing on the matter and halo power spectra, halo abundance and non-linear trans…
Peak exclusion, stochasticity and convergence of perturbative bias expansions in 1+1 gravity
Tobias Baldauf, Sandrine Codis, Vincent Desjacques +1
The Lagrangian peaks of a 1D cosmological random field representing dark matter are used as a proxy for a catalogue of biased tracers in order to investigate the small-scale exclus…
On the reach of perturbative methods for dark matter density fields
Tobias Baldauf, Emmanuel Schaan, Matias Zaldarriaga
We study the mapping from Lagrangian to Eulerian space in the context of the Effective Field Theory (EFT) of Large Scale Structure. We compute Lagrangian displacements with Lagrang…
The Effective Field Theory of Large Scale Structure at Two Loops: the apparent scale dependence of the speed of sound
Tobias Baldauf, Lorenzo Mercolli, Matias Zaldarriaga
We study the Effective Field Theory of Large Scale Structure for cosmic density and momentum fields. We show that the finite part of the two-loop calculation and its counterterms i…
On the reach of perturbative descriptions for dark matter displacement fields
Tobias Baldauf, Emmanuel Schaan, Matias Zaldarriaga
We study Lagrangian Perturbation Theory (LPT) and its regularization in the Effective Field Theory (EFT) approach. We evaluate the LPT displacement with the same phases as a corres…
Equivalence Principle and the Baryon Acoustic Peak
Tobias Baldauf, Mehrdad Mirbabayi, Marko Simonović +1
We study the dominant effect of a long wavelength density perturbation on short distance physics. In the non-relativistic limit, the result is a uniform acceleration, fixe…
