Rapid and robust simulation-based inference for kilonovae

Daniel Mortlock, Gurjeet Jagwani, Hiranya V. Peiris, Mattia Bulla, Nikhil Sarin, Samaya Nissanke, Stephanie M. Brown, Stephan Rosswog, Stephen Thorp

Simulation-based inference recovers kilonova parameters rapidly from light curves without the biases that affect MCMC fits to emulator outputs.

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

SBI provides a rapid alternative to MCMC for inference with emulators or approximate likelihoods that is robust to emulator uncertainty and likelihood misspecification.

C2weakest assumption

The Gaussian process emulator trained on the ~1300 POSSIS simulations fully captures the non-Gaussian, correlated structure of the predictive uncertainty, and the simulations themselves are sufficiently representative of real kilonova physics.

C3one line summary

Simulation-based inference with a Gaussian process emulator trained on ~1300 POSSIS simulations enables rapid, robust kilonova parameter estimation that avoids MCMC biases from likelihood misspecification.
