What parameter is responsible for the list of authors in Wordpress?

When editing pages there is a property like "Authors", where you can select the author of the page itself. From this, for custom roles, you can restrict access to their/other pages.

But the list displays only site administrators. What parameter is responsible for the access user roles in finding the list of authors?

Each user or user groups have certain rights.
For example, to publish articles (posts) can the following groups of users: Authors, Editors, Administrators, super administrator (WPMU). In the admin users of those groups you see.
You can set the users role editor plugin to add rights to a user or group of users.
