Non-Gaussian Galaxy Stochasticity and the Noise-Field Formulation
Henrique Rubira, Fabian Schmidt
We revisit the stochastic, or noise, contributions to the galaxy density field within the effective field theory (EFT) of large-scale structure. Starting from the general, all-orde…
Multi-tracer beyond linear theory
Henrique Rubira, Francesco Conteddu
The multi-tracer (MT) technique has been shown to outperform single-tracer analyses in the context of galaxy clustering. In this paper, we conduct a series of Fisher analyses to fu…
Gravitational waves from first-order phase transitions: from weak to strong
Chiara Caprini, Ryusuke Jinno, Thomas Konstandin +3
We study the generation of gravitational waves (GWs) during a cosmological first-order phase transition (PT) using the recently introduced Higgsless approach to numerically simulat…
The Renormalization Group for Large-Scale Structure: Primordial non-Gaussianities
Charalampos Nikolis, Henrique Rubira, Fabian Schmidt
The renormalization group for large-scale structure (RG-LSS) describes the evolution of galaxy bias and stochastic parameters as a function of the cutoff . In this work, we intr…
The Renormalization Group for Large-Scale Structure: Origin of Galaxy Stochasticity
Henrique Rubira, Fabian Schmidt
The renormalization group equations for large-scale structure (RG-LSS) describe how the bias and stochastic (noise) parameters -- both of matter and biased tracers such as galaxies…
Galaxy bias renormalization group
Henrique Rubira, Fabian Schmidt
The effective field theory of large-scale structure allows for a consistent perturbative bias expansion of the rest-frame galaxy density field. In this work, we present a systemati…
The Effective Field Theory of Large-Scale Structure and Multi-tracer II: redshift space and realistic tracers
Thiago Mergulhão, Henrique Rubira, Rodrigo Voivodic
We extend the multi-tracer (MT) formalism of the effective field theory of large-scale structure to redshift space, comparing the results of MT to a single-tracer analysis when ext…
Gravitational waves from defect-driven phase transitions: domain walls
Simone Blasi, Ryusuke Jinno, Thomas Konstandin +2
We discuss the gravitational wave spectrum produced by first-order phase transitions seeded by domain wall networks. This setup is important for many two-step phase transitions as…
Higgsless simulations of cosmological phase transitions and gravitational waves
Ryusuke Jinno, Thomas Konstandin, Henrique Rubira +1
First-order cosmological phase transitions in the early Universe source sound waves and, subsequently, a background of stochastic gravitational waves. Currently, predictions of the…
Machine Learning Post-Minkowskian Integrals
Ryusuke Jinno, Gregor Kälin, Zhengwen Liu +1
We study a neural network framework for the numerical evaluation of Feynman loop integrals that are fundamental building blocks for perturbative computations of physical observable…
Effect of density fluctuations on gravitational wave production in first-order phase transitions
Ryusuke Jinno, Thomas Konstandin, Henrique Rubira +1
We study the effect of density perturbations on the process of first-order phase transitions and gravitational wave production in the early Universe. We are mainly interested in ho…
The Effective Field Theory of Large-Scale Structure and Multi-tracer
Thiago Mergulhão, Henrique Rubira, Rodrigo Voivodic +1
We study the performance of the perturbative bias expansion when combined with the multi-tracer technique, and their impact on the extraction of cosmological parameters. We conside…
The Effective Field Theory and Perturbative Analysis for Log-Density Fields
Henrique Rubira, Rodrigo Voivodic
A logarithm transformation over the matter overdensity field brings information from the bispectrum and higher-order n-point functions to the power spectrum. We calculate the p…
A hybrid simulation of gravitational wave production in first-order phase transitions
Ryusuke Jinno, Thomas Konstandin, Henrique Rubira
The LISA telescope will provide the first opportunity to probe the scenario of a first-order phase transition happening close to the electroweak scale. By now, it is evident that t…
Deformation of the gravitational wave spectrum by density perturbations
Valerie Domcke, Ryusuke Jinno, Henrique Rubira
We study the effect of primordial scalar curvature perturbations on the propagation of gravitational waves over cosmic distances. We point out that such curvature perturbations def…

Mathias Garny, Thomas Konstandin, Henrique Rubira
We study the Schrödinger-Poisson (SP) method in the context of cosmological large-scale structure formation in an expanding background. In the limit , the SP technique…

Thomas Konstandin, Rafael A. Porto, Henrique Rubira
We study the power spectrum of dark matter density fluctuations in the framework of the Effective Field Theory of Large Scale Structures (EFTofLSS) up to three loop orders. In prin…
