Mitigating baryonic effects with a theoretical error covariance
Maria G. Moreira, Felipe Andrade-Oliveira, Xiao Fang +5
One of the primary sources of uncertainties in modeling the cosmic-shear power spectrum on small scales is the effect of baryonic physics. Accurate cosmology for Stage-IV surveys r…
Optimizing large-scale structure data analysis with the theoretical error likelihood
Anton Chudaykin, Mikhail M. Ivanov, Marko Simonović
An important aspect of large-scale structure data analysis is the presence of non-negligible theoretical uncertainties, which become increasingly important on small scales. We show…
Constraining Early Dark Energy with Large-Scale Structure
Mikhail M. Ivanov, Evan McDonough, J. Colin Hill +4
An axion-like field comprising of the energy density of the universe near matter-radiation equality is a candidate to resolve the Hubble tension; this is the "early dar…
Blinded challenge for precision cosmology with large-scale structure: results from effective field theory for the redshift-space galaxy power spectrum
Takahiro Nishimichi, Guido D'Amico, Mikhail M. Ivanov +5
An accurate theoretical template for the galaxy power spectrum is a key for the success of ongoing and future spectroscopic surveys. We examine to what extent the Effective Field T…
Combining Full-Shape and BAO Analyses of Galaxy Power Spectra: A 1.6% CMB-independent constraint on H0
Oliver H. E. Philcox, Mikhail M. Ivanov, Marko Simonović +1
We present cosmological constraints from a joint analysis of the pre- and post-reconstruction galaxy power spectrum multipoles from the final data release of the Baryon Oscillation…
Could quasar lensing time delays hint to a core component in halos, instead of H0 tension?
Kfir Blum, Emanuele Castorina, Marko Simonović
The time delay measured between the images of gravitationally lensed quasars probes a combination of the angular diameter distance to the source-lens system and the mass density pr…
Cosmological Parameters and Neutrino Masses from the Final Planck and Full-Shape BOSS Data
Mikhail M. Ivanov, Marko Simonović, Matias Zaldarriaga
We present a joint analysis of the Planck cosmic microwave background (CMB) and Baryon Oscillation Spectroscopic Survey (BOSS) final data releases. A key novelty of our study is th…
Cosmological Parameters from the BOSS Galaxy Power Spectrum
Mikhail M. Ivanov, Marko Simonović, Matias Zaldarriaga
We present cosmological parameter measurements from the publicly available Baryon Oscillation Spectroscopic Survey (BOSS) data on anisotropic galaxy clustering in Fourier space. Co…
Modeling Biased Tracers at the Field Level
Marcel Schmittfull, Marko Simonović, Valentin Assassi +1
In this paper we test the perturbative halo bias model at the field level. The advantage of this approach is that any analysis can be done without sample variance if the same initi…
Beyond the traditional Line-of-Sight approach of cosmological angular statistics
Nils Schöneberg, Marko Simonović, Julien Lesgourgues +1
We present a new efficient method to compute the angular power spectra of large-scale structure observables that circumvents the numerical integration over Bessel functions, expand…
Cosmological Perturbation Theory Using the FFTLog: Formalism and Connection to QFT Loop Integrals
Marko Simonović, Tobias Baldauf, Matias Zaldarriaga +2
We present a new method for calculating loops in cosmological perturbation theory. This method is based on approximating a CDM-like cosmology as a finite sum of complex power-la…
Weinberg Soft Theorems from Weinberg Adiabatic Modes
Mehrdad Mirbabayi, Marko Simonović
Soft theorems for the scattering of low energy photons and gravitons and cosmological consistency conditions on the squeezed-limit correlation functions are both understood to be c…
LSS constraints with controlled theoretical uncertainties
Tobias Baldauf, Mehrdad Mirbabayi, Marko Simonović +1
Forecasts and analyses of cosmological observations often rely on the assumption of a perfect theoretical model over a defined range of scales. We explore how model uncertainties a…
Effective Theory of Squeezed Correlation Functions
Mehrdad Mirbabayi, Marko Simonović
Various inflationary scenarios can often be distinguished from one another by looking at the squeezed limit behavior of correlation functions. Therefore, it is useful to have a fra…
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…
Detecting Primordial -Modes after Planck
Paolo Creminelli, Diana López Nacir, Marko Simonović +2
We update the forecasts for the measurement of the tensor-to-scalar ratio for various ground-based experiments (AdvACT, CLASS, Keck/BICEP3, Simons Array, SPT-3G), balloons (EBE…
Baryon Acoustic Peak and the Squeezed Limit Bispectrum
Mehrdad Mirbabayi, Marko Simonović, Matias Zaldarriaga
In the non-relativistic regime, pertinent to the large scale structure of the Universe, the leading effect of a long-wavelength perturbation on short distance physics is a…
Implications of the scalar tilt for the tensor-to-scalar ratio
Paolo Creminelli, Sergei Dubovsky, Diana López Nacir +4
We investigate the possible implications of the measured value of the scalar tilt for the tensor-to-scalar ratio in slow-roll, single-field inflationary models. The measu…
Inflation at its Endpoint
Paolo Creminelli, Diana López Nacir, Marko Simonović +2
In the simplest inflationary model , we provide a prediction accurate up to for the spectral index and the tensor-to-scalar ratio assuming instant…
Single-Field Consistency Relations of Large Scale Structure. Part III: Test of the Equivalence Principle
Paolo Creminelli, Jérôme Gleyzes, Lam Hui +2
The recently derived consistency relations for Large Scale Structure do not hold if the Equivalence Principle (EP) is violated. We show it explicitly in a toy model with two fluids…
Single-Field Consistency Relations of Large Scale Structure. Part II: Resummation and Redshift Space
Paolo Creminelli, Jérôme Gleyzes, Marko Simonović +1
We generalize the recently derived single-field consistency relations of Large Scale Structure in two directions. First, we treat the effect of the long modes (with momentum q) on…
Single-Field Consistency Relations of Large Scale Structure
Paolo Creminelli, Jorge Noreña, Marko Simonović +1

The Physical Squeezed Limit: Consistency Relations at Order q^2
Paolo Creminelli, Ashley Perko, Leonardo Senatore +2
In single-field models of inflation the effect of a long mode with momentum q reduces to a diffeomorphism at zeroth and first order in q. This gives the well-known consistency rela…
ISO(4,1) Symmetry in the EFT of Inflation
Paolo Creminelli, Razieh Emami, Marko Simonović +1
In DBI inflation the cubic action is a particular linear combination of the two, otherwise independent, cubic operators \dot π^3 and \dot π(\partial_i π)^2. We show that in the Eff…
