Two-loop renormalization and running of galaxy bias
Thomas Bakx, Mathias Garny, Henrique Rubira +1
We systematically extend the framework of galaxy bias renormalization to two-loop order. For the minimal complete basis of 29 deterministic bias operators up to fifth order in the…
Galaxy bias renormalization: Two-loop Power Spectrum, One-loop Trispectrum and Bispectrum
Thomas Bakx, Mathias Garny, Henrique Rubira +1
We present a complete treatment of fifth-order renormalized galaxy bias at the one- and two-loop level in real space, including gradient corrections to deterministic bias operators…
Towards the Two-Loop EFTofLSS in Galaxy Lensing Surveys
Evan Saraivanov, Henrique Rubira, Vivian Miranda +1
Extracting cosmological information from Stage IV weak lensing surveys requires non-linear modelling of the matter power spectrum that is accurate across a broad range of scales an…
Rapid cosmological inference with the two-loop matter power spectrum
Thomas Bakx, Henrique Rubira, Nora Elisa Chisari +1
We compute the two-loop effective field theory (EFT) power spectrum of dark matter density fluctuations in CDM using the recently proposed COBRA method (Bakx. et al, 2025). Wit…
Hot New Early Dark Energy: Dark Radiation Matter Decoupling
Mathias Garny, Florian Niedermann, Henrique Rubira +1
We present a microscopic model of the dark sector that resolves the Hubble tension within standard current datasets based on well-known fundamental principles, gauge symmetry and s…
Interacting Dark Sector (ETHOS ): Cosmological Constraints from SPT Cluster Abundance with DES and HST Weak Lensing Data
A. Mazoun, S. Bocquet, J. J. Mohr +64
We use galaxy cluster abundance measurements from the South Pole Telescope (SPT) enhanced by Multi-Component Matched Filter (MCMF) confirmation and complemented with mass informati…
