# Constraining the general reheating phase in the $\alpha$-attractor inflationary cosmology

## TL;DR

This paper constrains the duration, temperature, and equation-of-state of the reheating phase in $ ext{alpha}$-attractor inflation models using cosmological data, informing future observational prospects.

## Contribution

It provides model-independent constraints on reheating parameters within superconformal $ ext{alpha}$-attractor inflation, considering future cosmological measurements.

## Key findings

- Constraints on reheating duration $N_{reh}$ and temperature $T_{reh}$.
- Favored equation-of-state parameters $w_{reh}$ for different scenarios.
- Analysis independent of reheating details, based on tensor-to-scalar ratio $r$ measurements.

## Abstract

In this paper we constrain some aspects of the general postinflationary phase in the context of superconformal $\alpha$-attractor models of inflation. In particular, we provide constraints on the duration of the reheating process, $N_{reh}$, and on the reheating temperature, $T_{reh}$, simulating possible and future results given by the next-generation of cosmological missions. Moreover, we stress what kinds of equation-of-state parameter, $w_{reh}$, are favored for different scenarios. The analysis does not depend on the details of the reheating phase and it is performed assuming different measurements of the tensor-to-scalar ratio $r$.
