It has recently been pointed out that Gaia is capable of detecting a stochastic gravitational wave background in the sensitivity band between the frequency of pulsar timing arrays and LISA. We argue that Gaia and THEIA has great potential for early universe cosmology, since such a frequency range is ideal for probing phase transitions in asymmetric dark matter, SIMP and the cosmological QCD transition. Furthermore, there is the potential for detecting primordial black holes in the solar mass range produced during such an early universe transition and distinguish them from those expected from the QCD epoch. Finally, we discuss the potential for Gaia and THEIA to probe topological defects and the ability of Gaia to potentially shed light on the recent NANOGrav results.

Dark Phoenix: dark matter relic from its own decay
A transient post-freeze-out decay window for dark matter, closed by a first-order phase transition that jumps a partner mass, can reduce an overproduced thermal relic to the observed abundance.

Primordial Black Hole from Tensor-induced Density Fluctuation: First-order Phase Transitions and Domain Walls
Tensor perturbations from FOPT and domain-wall sources are claimed to induce second-order scalar perturbations large enough to form primordial black holes, potentially all of the dark matter.

New test of modified gravity with gravitational wave experiments
For a stationary, isotropic gravitational wave background, three-point correlations are produced only by scalar polarizations, giving a new null test for modified gravity.

A Non-Holomorphic Modular $A_4$ Framework for Resonant Leptogenesis with Gravitational Wave Signatures
A non-holomorphic modular A4 seesaw model yields quasi-degenerate right-handed neutrinos, enabling resonant leptogenesis at ~10^6 GeV and a double-peaked gravitational-wave signature.

Gravitational waves from seesaw assisted collapsing domain walls
Right-handed-neutrino couplings generate the energy bias that collapses Z2 domain walls, linking the type-I seesaw mass scale to observable gravitational-wave peaks and to resonant leptogenesis.

Impact of First-order Electroweak Phase Transition on QCD Axion
A temporary axion mass spike during a first-order electroweak phase transition can make the QCD axion dark matter over a wide range of decay constants without a tuned initial angle.
