It is a giant elliptical galaxy that is surrounded by an expanding cluster of other galaxies. In 2018, the National Radio Astronomy Observatory captured a cosmic meteorological event using ALMA that had never been seen before: a group of towering intergalactic gas clouds raining down on the supermassive black hole at the center of the huge galaxy. The black hole draws in a large amount of cold molecular gas and sprays it again in a continuous cycle to make it look like a gigantic fountain. It is also known for being the brightest cluster from Earth.
Here there is more information.
This is the spectra that I found:
Peak A equals to Vanidium
Peak B equals to nickel
Peak C equals to kripton
The total area is 23484441
Peak A area=6349251--------------
Peak B area=5534945--------------
Peak C area=1222789---------------
The results are:
19.5% of vanidium in peak A
23.6% of nickel in peak B
5.21% of kripton in peak C
Looking for some scientific researches I have found this artcle , in it, they say that it is a a celestial body with many metallic elements. They do not mention those previously said by me since in the article they focus more on gas elements such as hydrogen. Despite this, I think that my answer is not wrong because the three elements named by me are metals.
