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: 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…
