✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Gravitational waves from cosmic inflation could have originated the gravitational-wave signal sought by the NANOGrav observatory.

C2weakest assumption

That the stochastic gravitational wave background targeted by NANOGrav is produced by primordial inflation rather than by astrophysical sources such as supermassive black hole binaries.

C3one line summary

Dissertation investigates gravitational waves produced during cosmic inflation as a possible origin for the nanohertz stochastic background sought by NANOGrav.
