The fit of the data was made considering that the synchrotron emission is affected by free-free absorption at low frequencies. The value we obtained for the optical depth at 74 MHz is τ74 = 1.06±0.09, showing that there is strong absorption in that region. The study from which this data was obtained, indicate that the medium responsible for the absorption could be a thermal ionized gas linked to the SNR itself5 p.application/pdfengcc-by-nc-nd (c) Cabanas, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/Radiació sincrotrònicaSupernovesTreballs de fi de grauSynchrotron radiationSupernovaeBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
