X-Ray Observations of Old Nearby Supernovae: Constraints on Compact Object Populations and Late Interaction
Julia Ahlvind, Josefin Larsson, Dennis Alp
The properties of the population of compact objects created in core-collapse supernovae (SNe) are uncertain. X-ray observations years to decades after the explosions offer a way to…
