I have analyzed the spectrum of the SN Refsdal.
Then, I have calculated the percentage of each element with respect to the total area.
The results I have obtained are the following:
TOTAL AREA: 87443
AREA PEAK 1 %= (43336/87443) x 100 = 45,55% Iron
SCIENTIFIC ARTICLES:
I have compared my results with a scientific article (https://iopscience.iop.org/article/10.1088/2041-8205/804/1/L14/meta#apjl511665s3). In it he explains that the elements found in SN Refsdal are metallic and the most common are iron, oxygen and hydrogen.
