Events
In order to assist astronomers in taking, analysing and interpreting multi-wavelength/multi-messenger observations and coordinating efforts to observe the transient sky, it is essential to provide training in the different domains through conferences, workshops, schools and hackathons and through providing dedicated training material. There will be a strong synergy with the other actions to reinforce the access to different facilities, help in the acquisition of scientific expertise, improve collaboration for accessing data, as well as facilitate coordination activities in observing transient events.
