Models of Millimeter and Radio Emission from Interacting Supernovae

Understand

This work utilizes established models of synchrotron-powered light curves for core-collapse supernovae in dense circumstellar environments, namely type IIn and Ibn, to demonstrate the potential for detecting millimeter emission from these events.

• The progenitor types of these supernovae are still an open question, but using the synchrotron light curves as probes for the circumstellar environments could shed light on the mass-loss histories of the progenitors and discern between different theories.
• Observations in millimeter bands are particularly fruitful, as they probe regions at smaller radii and higher ambient densities, where centimeter emission tends to be self-absorbed.
• In our application of these light curves, we explore a diversity of progenitor types and mass-loss profiles to understand their effects on the light curve shapes.
