Biased tracers, Hybrid Effective Field Theory and Modified Gravity
Guilherme Brando, Baojiu Li, Kazuya Koyama
The modelling of the power spectrum of biased tracers has become a central topic in the analysis of modern cosmological galaxy surveys. Perturbative templates formulated in both Eu…
The sound of dynamical dark energy and modified gravity
João Rebouças, Guilherme Brando, Felipe T. Falciano +1
Different candidate models are able to reproduce the dynamical dark energy signal preferred by combinations of recent distance measurements. These models may be distinguished by th…
Modeling nonlinear scales for dynamical dark energy cosmologies with COLA
João Rebouças, Victoria Lloyd, Jonathan Gordon +2
Upcoming galaxy surveys will bring a wealth of information about the clustering of matter, but modeling small-scale structure beyond CDM remains computationally challenging. Wh…
Gravitational wave lensing: probing Fuzzy Dark Matter with LISA
Shashwat Singh, Guilherme Brando, Stefano Savastano +1
Gravitational lensing is a universal phenomenon: it affects both gravitational waves (GWs) and electromagnetic signals travelling through the gravitational field of a massive objec…
