Abstract:<br aria-hidden="true">
The properties of compact objects formed in core-collapse supernovae (SNe) remain uncertain. X-ray observations years to decades after explosion provide a way to probe these young remnants, as hard emission from the central regions can emerge once the ejecta
becomes sufficiently transparent. In this talk, I will present a systematic study of late-time X-ray emission from 242 nearby core-collapse SNe based on more than 600 archival observations. I will show new X-ray SN detections, highlight one case with a possible
hard central component, and demonstrate how upper limits from the full sample can be used to constrain the young pulsar population.<br>
