List of referenced entities

Question

I am trying to make a list of entities I have made in my text.

\begin{document}
\section{Bla}
bla bla bla
\section{Model 1 \label{mod:mod_1}}
bla bla bla
\section {Blubb}
blubb blubb blubb
\section {Model 2 \label{mod:mod_2}
blub bla bla
% Here I want a list of Models
\end{document}

With \label I can label my entities and call them with \ref, but how do I easily make a table of all labels with the mod: marker?

Thank you!
