 Support for particles was originally introduced in \dealii{} version 9.0. In \dealii,
 particles can be used as passive tracers, or as part of more complex
-models such as those based on Particle-In-Cells (PIC) approaches \cite{gassmoller2018flexible}.
+models such as those based on Particle-In-Cells (PIC) approaches \cite{GLHPB18}.
 
 With the current release, the support for particles has been further expanded: New parallel
  insertion mechanisms and a basic interface to post-process particles have
