Surrogate light curve models for kilonovae with comprehensive wind ejecta outflows and parameter estimation for AT2017gfo

The electromagnetic emission resulting from neutron star mergers have been shown to encode properties of the ejected material in their light curves. ejecta inferred kilonova has tension with those calculated based on gravitational wave signal and numerical relativity models. Motivated by this tension, we construct a broad set surrogate curve models derived for ejecta. four-parameter family two-dimensional anisotropic simulations its associated explore different assumptions about wind outflow morphology composition, keeping dynamical component consistent. We present capabilities these interpolating curves across various parameters perform parameter estimation AT2017gfo both without any under assumption that must be representative solar $r$-process abundance patterns. Our shows help alleviate property discrepancy while also illustrating impact systematic modeling uncertainties properties, urging further investigation.
