The 15th International LISA Symposium was attended by over 400 researchers and featured a program dedicated to gravitational wave astrophysics, with particular emphasis on sources that can be observed in the millihertz band by the LISA, the current status and unique challenges in gravitational theory and analysis for LISA sources, and the latest updates on the development of the LISA mission.

The Symposium was hosted by the Relativity Group at University College Dublin. Further details can be found on the Symposium website, which includes videos of the plenary talks.
