Measurements of such spectra on the Ukrainian GURT and URAN-2 radio telescopes with the French NenuFAR one due to the contribution of ionized gas inside and outside remnants will be a significant result. This will allow us to estimate the temperature, average ionization, and emission measure of the absorbing gas into the remnants and the surrounding interstellar medium. popup.nrat_date 2024-12-09 Close
