How can I select a set of nodes directly linked to a node using views and wikitools
So I found a very simple solution to my problem: I used a contextual filter (in Views) and a Node Reference. Each Article page is linked to corresponding Author page(s) using a node reference. Then using a Contextual Filter in Views, I was able to select all articles written by a given author and display them in the author's page.

I'll give additional details on how to set up the contextual filter, even though it might seem simple to experienced users, new users like me might find the information useful. To set up the contextual filter for the task I described, I selected: 'Provide default value' ('Content ID from URL'), then 'Override title' (and I entered "Articles mentioning %1" in the blank space), 'Specify validation criteria' ('Content', 'Author pages') and 'Node ID' as filter value format.

I don't know whether it can be helpful to someone else but I would have saved a lot of time if I had found that information earlier... :)
