I am studying a paper The effect of star formation history on the inferred stellar initial mass function and trying to reproduce the given results.

According equation (1) in the paper, the inferred IMF f(M) can be determined if the PDMF phi(M) and the star formation history S(t) is known. I am trying to calculate S(t) as per the description given in that paper in vain. Roughly, by what amount will the slope of f(M) change from phi(M) if S(t) is calculated? Example: If phi(M) = M^(-2.5), then by what amount will the index change in f(M) if S(t) is calculated and inserted into equation (1)?

    $\begingroup$ It seems that you have not asked any specific questions, and thus it sounds like a "do my work for me" kind of question. Please provide details for the concepts you are confused about. If you don't understand the basics, describe what concepts are confusing. The more detailed your question, the better answers it will attract. $\endgroup$ – Daddy Kropotkin May 12 at 14:50

  • $\begingroup$ @KrishnaKumarKowshik - Put that clarification into the question. That would improve it a lot. $\endgroup$ – Anders Sandberg May 13 at 7:48

    $\begingroup$ No worries! :) Thank you for clarifying. This will probably attract more people now. I've added +1 $\endgroup$ – Daddy Kropotkin May 13 at 13:10
