Reheating is a process where the energy density of a dominant component of the universe other than radiation, such as a matter component, is transferred into radiation. It is usually assumed that the temperature of the universe decreases due to cosmic expansion even during the reheating process, in which case the maximal temperature of the universe is much higher than the reheat temperature. We point out that the temperature of the universe during reheating may in fact increase in well-motivated scenarios. We derive the necessary conditions for the temperature to increase during reheating and discuss concrete examples involving a scalar field. We comment on implications for particle physics and cosmology due to an increasing temperature during reheating.

Light PIDM in Warped Extra Dimensions
A UV-Dark-IR brane construction in warped 5D space allows light (MeV-TeV) purely gravitational dark matter to freeze in with TeV-scale reheating temperatures.

Baryon-dark matter coincidence in Randall-Sundrum Model
Graviton- and radion-mediated freeze-in in a Randall-Sundrum model can match the observed dark matter relic abundance, and TeV-scale resonant leptogenesis through the same portals can match the observed baryon asymmet...

Primordial Gravitational Waves from Phase Transitions during Reheating
Phase transitions happening during reheating can produce gravitational-wave signals that are delayed, prolonged, and shifted in amplitude and frequency by orders of magnitude compared with standard cosmology.
