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…

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 data sets (Planck 2018, Pantheon+ and DESI DR2 BAO) based on well-known f…

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). With…

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…

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…

Hot New Early Dark Energy bridging cosmic gaps: Supercooled phase transition reconciles (stepped) dark radiation solutions to the Hubble tension with BBN

Mathias Garny, Florian Niedermann, Henrique Rubira +1

We propose a simple model that can alleviate the tension while remaining consistent with big bang nucleosynthesis (BBN). It is based on a dark sector described by a standard…

Probing interacting dark sector models with future weak lensing-informed galaxy cluster abundance constraints from SPT-3G and CMB-S4

Asmaa Mazoun, Sebastian Bocquet, Mathias Garny +3

We forecast the sensitivity of ongoing and future galaxy cluster abundance measurements to detect deviations from the cold dark matter (CDM) paradigm. Concretely, we consider a cla…

Full-shape BOSS constraints on dark matter interacting with dark radiation and lifting the tension

Henrique Rubira, Asmaa Mazoun, Mathias Garny

In this work we derive constraints on interacting dark matter-dark radiation models from a full-shape analysis of BOSS-DR12 galaxy clustering data, combined with Planck legacy cosm…
