Limits on axion-like particles from photon-coupling searches are recast as constraints on massive graviton-like particles across lab, astrophysical, and cosmological experiments using analogous Primakoff and Gertsenshtein conversion mechanisms.

The minimal majoron framework permits simultaneous majoron dark matter and thermal leptogenesis in a constrained cosmological window set by freeze-in production, warm dark matter bounds, and indirect detection limits.
In the left-right asymmetry model, differing neutron and antineutron lifetimes during the QCD phase transition generate baryon asymmetry while escaping sterile neutrinos produce opposite lepton asymmetry.
Future MeV telescopes are projected to improve existing limits on sterile neutrino dark matter decay rates by several orders of magnitude.
Gamma-ray observations impose an upper bound of order 1 GeV on the mass of a photon-coupled scalar dark matter candidate produced via thermal misalignment.
A comprehensive formulation is given for the angular power spectrum of photons from dark matter annihilation or decay, stressing that detector energy resolution is essential for accurate evaluation of line photon signals.
