An EFT with inflaton-dependent axion kinetic term organizes direct decay and annihilation production during reheating, yielding ΔN_eff contributions that scale as T_rh^{-2} and T_rh^{4/3} respectively and allowing a two-dimensional map of constraints on Wilson coefficients and reheating temperature.
Freeze-in dark matter produced by kaons in low-reheating cosmologies requires larger couplings at lower reheating temperatures, directly linking the relic density to observable rates in rare kaon decay experiments.
Electroweak SU(2)_L doublet fermion dark matter with mass above 10^10 GeV (or 300 GeV if pseudo-Dirac) is produced by Boltzmann-suppressed freeze-in above the reheat temperature and evades direct detection while never thermalizing.
Stronger couplings or inflaton-seeded initial abundance allow freeze-in dark matter to match the relic density while evading DAMIC-M and PandaX bounds for reheating temperatures below the electroweak scale.
The micrOMEGAs dark-matter package now solves Boltzmann equations with user-defined expansion and entropy histories, adds sub-GeV hadronic annihilation, and updates CMB, dwarf-galaxy, LZ, and CMS constraints.
Freeze-in at low reheating temperatures allows MeV-scale dark matter in vector portal models to be probed by future direct detection experiments in nuclear recoils for 50-500 MeV masses and via enhanced solar neutrino coherent scattering.
Gravitational scalar production yields reheating-dependent constraints on dark matter scalars, with dilution preserving viability for k<4 low-temperature reheating and factorization in multi-stage cases.
Variations in pre-nucleosynthesis cosmology produce distinct seasons in the phase-space distribution of freeze-in dark matter, directly affecting its warmness and mass bounds.
Dipole dark matter produced by freeze-out or freeze-in, including entropy dilution from reheating, can be probed via neutron star heating due to momentum-dependent electromagnetic interactions.
