Restricting CP violation in the low-scale type-I seesaw with three right-handed neutrinos to the Dirac phase δ alone yields specific testable subregions of heavy-neutrino flavor mixings and permits low-scale leptogenesis to generate the observed baryon asymmetry even for O(10^{-5}) deviations from C

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.
ULYSSES v3 extends an open-source Python toolkit to numerically solve leptogenesis equations in resonant low-scale and high-scale regimes with updated interfaces and cross-checks.
In the minimal Majoron model the particle can explain all dark matter with mass below about 10 MeV from misalignment or freeze-in, and remains compatible with thermal leptogenesis when misalignment dominates or with mild tuning.
