Description

The Large Magellanic Cloud (LMC) is one of our nearest galactic neighbours and has been well-surveyed at multiple frequencies. A recent MeerKAT radio-continuum survey provides unprecedented sensitivity and resolution of the LMC, revealing its supernova remnant (SNR) population in greater detail than previously seen. Combining this new data with previous multi-frequency surveys, I have characterized the entire visible LMC SNR population. This catalogue enables statistical analysis of morphological and spectral properties including diameter, ovality, age, and spectral indices. Statistical tests, such as comparing core-collapse and thermonuclear SNR populations, can help reveal distinctive evolutionary patterns. This work provides a comprehensive radio foundation for understanding the LMC SNR population, complementing future multi-frequency observations and surveys, such as the upcoming CTA surveys.
