Towards a fast implementation and renormalization of the two-loop EFT
Described in: Renormalization and fast computation
Collaboration with: Mathias Garny, Thomas Bakx, Zvonimir Vlah, Elisa Chisari
We describe how the galaxy bias parameters evolve as a function of the energy scale considered, similarly to the RG-flow from particle physics.
Described in: Bias RG-flow, with stochasticity, with PNG, at two-loops
Collaboration with: Fabian Schmidt, Charalampos Nikolis, Mathias Garny, Thomas Bakx, Zvonimir Vlah
We generalize the EFTofLSS approach to include multiple tracers. We find ~40% improvement in the extraction of cosmological parameters.
Described in: Real space, Redshift space, Fisher analysis
Collaboration with: Thiago Mergulhão, Rodrigo Voivodic, Raul Abramo, Francesco Conteddu
I am also interested in how we can probe models beyond Lambda-CDM with LSS and CMB data
Described in: IDM-DR, IDM-DR with Clusters, IDM-DR in data, HNEDE, HNEDE with interactions
Collaboration with: Mathias Garny, Asmaa Mazoun, Joe Mohr, Sebastian Bocquet, Florian Niedermann, Martin Sloth
We extend the EFTofLSS framework to 3-loops, showing that the perturbative series behaves as an asymptotic series and discussing the convergence radius of the theory.
Described in: 3Loop
Collaboration with: Thomas Konstandin, Rafael Porto
We generalize the Halo Model to include voids and dust, showing that it improves the transition between the 1Halo and 2Halo term. The Halo Void model also solves the normalization issues with the halo mass function.
Described in: HaloVoidDust
Collaboration with: Rodrigo Voivodic, Marcos Lima
We develop a Schrödinger-Poisson code to account for the evolution of the BAO scale
Described in: SP
Collaboration with: Mathias Garny, Thomas Konstandin
We implement the EFTofLSS framework to log-transformed field, showing that this field is more Gaussian and linear
Described in: LogEFT
Collaboration with: Rodrigo Voivodic
