And which data should i use, after getting data which software can plot it. Here are software in this site but dont know which one to choose- https://lambda.gsfc.nasa.gov/toolbox/ , since i am learning python so that i can plot it, can anyone give me some paper about finding only the dark energy(I have read some few paper but its very hard to understand) and how to do the every thing to calculate the content of dark energy, I will be very grateful if anyone help me out of this.

  • $\begingroup$ You must be misunderstanding something . In this link there is the current modeling that connects dark mass, dark energy, and the CMB: physicsworld.com/a/… . I have a problem with loading the link you give, but afaik only indications of the need for dark energy and dark mass can be expected from the study of the CMB anisotropies. Certainly the"content of dark mass " is a matter of current research in particle physics experiments and astronomical observations. Dark energy $\endgroup$ – anna v Dec 30 '18 at 17:52
  • $\begingroup$ is even worse en.wikipedia.org/wiki/… $\endgroup$ – anna v Dec 30 '18 at 17:53
  • $\begingroup$ thank you anna v, but how can we calculate the CMB anisotropies, $\endgroup$ – Kabin Ghimire Dec 31 '18 at 9:39
  • $\begingroup$ Try understanding the paper arxiv.org/abs/1105.0419 . If you cannot understand it , it means that you need a physics background which can only be gained by studying the appropriate graduate courses. $\endgroup$ – anna v Dec 31 '18 at 11:53
