Description
By combining data from different messengers (electromagnetic radiation, gravitational waves, neutrinos, cosmic rays, ...), one can gain a better understanding of the physics in the universe. A milestone was the merger of a binary neutron star (2017) seen in gravitational waves by LIGO/Virgo, followed by gamma-ray burst, optical/infrared kilonova, X-ray, and radio counterparts.
There are important challenges, for example:
- many messengers are hard to detect,
- transients often evolve quickly, i.e. a rapid observation of follow-ups is needed,
- the variety, the velocity, and the volume of data is large in general.
The German Center for Astrophysics (DZA) will provide archives with data from observatories and telescopes around the world. One of the main tasks will be to make it easier for different communities (EM, GW, EM, neutrino, cosmic ray) to cross-match data. This requires standardized data Formats, open data, and uniform access.
This session will provide a brief overview of the topic, followed by presentations from representatives of a few archives on their workflows and possible strategies for facilitating access, including job processing, federated authentication and authorization infrastructures (AAI) as well as accounting.
The aim of the subsequent discussion is to better understand the challenges involved in implementing multi-messaging and the needs of the various messenger communities, ultimately enabling the DZA to build a suitable infrastructure that best meets the communities' requirements.
