I am trying to study the evolution of some galaxies and, to do so, I am analysing their merger trees. I calculated the number of mergers they have had during their evolution history and now I would like to find out at which epoch did they occur. Is it possible to trace these mergers to a specific redshift? If so, how can I do this?
Many thanks in advance.
A previous question might be useful here.
Thank you, Dylan!
I did the API request for the "sublink/simple.json" and used the 'Mergers' field to analyse the subhalos mergers. However, I don't think I understand the return I got because, for example, for the subhalo with ID=11 at z=0 I got as the first element of the list "[80, 20419]". Does that mean that in the 80th snapshot it had 20419 mergers? Isn't it an enormous amount of mergers for one subhalo to have at only one snapshot?
You can find a description of what the return value is in the API documentation (search for "simple.json").
