Tensor perturbations from first-order phase transitions and domain wall annihilation induce curvature fluctuations at second order that form primordial black holes, allowing asteroid-mass PBHs to comprise all dark matter for specific parameter ranges with associated gravitational wave peaks in LISA,
Lepton parity stabilizes a Majorana fermion as freeze-in dark matter produced via right-handed neutrino or Higgs decays, yielding detectable gravitational waves or ΔN_eff depending on scalar couplings.
Spontaneous wash-in leptogenesis in Type II Seesaw with Majoron pNGB background enables baryon asymmetry generation alongside dark matter cogenesis for specific v_T, v_sigma and m_j ranges.
Forecasts indicate Simons Observatory could reach 1.5-2.3 sigma sensitivity to sub-10 arcsecond lensing from a cosmic texture using temperature and polarization channels, with polarization boosting signal-to-noise by about 67 percent.
Singlet-doublet dark matter induces radiative neutrino masses at one loop while enabling TeV-scale leptogenesis in both Majorana and Dirac realizations.
