Universal CMB Phase Coherence from Single-Field Inflation
Siméon Vareilles, Thomas Colas, Julien Grain +2
The phase coherence of primordial perturbations shapes the acoustic peaks of the CMB and is regarded as a key signature of inflation. Inflationary scenarios at different energy sca…
Primordial non-Gaussianity constraints on dissipative inflation
Santiago Agüí Salcedo, Thomas Colas, Petar Suman +3
Dissipative effects appear in many early-Universe scenarios, yet their universal observational signatures and systematic confrontation with data remain largely unexplored. We emplo…
Phenomenology of an Open Effective Field Theory of Dark Energy
Santiago Agüí Salcedo, Thomas Colas, Lennard Dufner +1
All observational evidence for dark matter and dark energy is so far exclusively gravitational. Hence, the dark sector may be equivalently described by a theory of the spacetime me…
Quantum estimation of cosmological parameters
Michał Piotrak, Thomas Colas, Ana Alonso-Serrano +1
Understanding how well future cosmological experiments can reconstruct the mechanism that generated primordial inhomogeneities is key to assessing the extent to which cosmology can…
Open Effective Field Theories for cosmology
Thomas Colas
When energy is not conserved, imprints of new physics on observable cosmology might not follow the rules of local effective actions. By capturing dissipative and diffusive effects,…
Efficient Cosmological Analysis of the SDSS/BOSS data from the Effective Field Theory of Large-Scale Structure
Thomas Colas, Guido D'Amico, Leonardo Senatore +2
The precision of the cosmological data allows us to accurately approximate the predictions for cosmological observables by Taylor expanding up to a low order the dependence on the…
