Plagiarism of former supervisors copying from my master thesis I graduated a couple of years ago performing a master thesis with two supervisors. They both were happy about it and wanted to write a paper from my thesis, including me as author, but after my graduation I didn't hear from them again. It is worth to say that my supervisors had the pdf file of my thesis and all the figures and plots in vector graphics.

To my surprise and deception, I found out that my two former supervisors have published a journal paper based on my master thesis, which is not cited. Not only they have reported all of my plots, but they have also copied the captions (with almost no modifications), equations, tables, and entire sentences (some of them just copy-pasted, other ones with very minor modifications). Moreover, the simulations section reports 2 simulations that I carried out during my thesis, and both the parameters, the plots, and the analysis of the simulations is basically copied from my thesis. After all this content taken from my thesis, I only see that the authors have just acknowledged me in the article for the simulations only, and not even for all the plots and all the sentences they used.

Needless to say, this situation makes me very angry and frustrated. I would like to know, given this situation, whether:


I can accuse my former supervisors of plagiarism, contacting the editor of the journal and proving that a very large portion of the paper is taken from my thesis, which is not cited. Although my thesis is not available online, the authors could have included it in the list of references, and I can prove that they have a copy of it;
I can ask to be included as author of the paper, since most of the work published is based on my master thesis, and not only the "simulations", as the authors wrote in the acknowledgements.

Yes, you can do that.

Yes, you can also do that.  Based on the information in the question, you should be an author on the paper.  I suggest you contact your supervisors and ask them to fix the author list first.  If that is unsuccessful, you should follow your university's grievance procedure.  Contacting the editor should be the last resort.
