Tip! Refine or expand your search. Authors are sometimes listed as 'Smith, J. K.' instead of 'Smith, John' so it is useful to search for last names only. Note this is currently a simple phrase search.

[ascl:2508.017] SIGWAY: Compute second-order, scalar induced gravitational wave signals

The SIGWAY data analysis pipeline computes second-order, scalar induced gravitational wave signals emitted by curvature perturbations in the early universe. The package solves the Mukhanov-Sasaki equation for single field ultra-slow roll inflationary models and computes the primordial scalar power spectrum Pζ. SIGWAY also computes the second order gravitational wave power spectrum ΩGW from P ζ for reentry during radiation domination or a phase of early matter domination.
