The Future of Primordial Features with Large-Scale Structure Surveys

Understand

Primordial features are one of the most important extensions of the Standard Model of cosmology, providing a wealth of information on the primordial universe, ranging from discrimination between inflation and alternative scenarios, new particle detection, to fine structures in the inflationary potential.

• We study the prospects of future large-scale structure (LSS) surveys on the detection and constraints of these features.
• We classify primordial feature models into several classes, and for each class we present a simple template of power spectrum that encodes the essential physics.
• We study how well the most ambitious LSS surveys proposed to date, including both spectroscopic and photometric surveys, will be able to improve the constraints with respect to the current Planck data.
