$\alpha$-attractor dark energy in view of next-generation cosmological surveys

Understand

The $\alpha$-attractor inflationary models are nowadays favored by CMB Planck observations.

• Their similarity with canonical quintessence models motivates the exploration of a common framework that explains both inflation and dark energy.
• We study the expected constraints that next-generation cosmological experiments will be able to impose for the dark energy $\alpha$-attractor model.
• We systematically account for the constraining power of SNIa from WFIRST, BAO from DESI and WFIRST, galaxy clustering and shear from LSST and Stage-4 CMB experiments.
