Redback: A Bayesian inference software package for electromagnetic transients

Understand

Fulfilling the rich promise of rapid advances in time-domain astronomy is only possible through confronting our observations with physical models and extracting the parameters that best describe what we see.

• Here, we introduce {\sc Redback}; a Bayesian inference software package for electromagnetic transients.
• {\sc Redback} provides an object-orientated {\sc python} interface to over 12 different samplers and over 100 different models for kilonovae, supernovae, gamma-ray burst afterglows, tidal disruption events, engine-driven transients among other explosive transients.
• The models range in complexity from simple analytical and semi-analytical models to surrogates built upon numerical simulations accelerated via machine learning.
