Astro-COLIBRI vs. SNEWS Events Utilizzo e statistiche
Flares of known astronomical sources and new transient phenomena occur on different timescales, from sub-seconds to several days or weeks. The discovery potential of both serendipitous observations and multi-messenger and multi-wavelength follow-up observations could be maximized with a tool which allows for quickly acquiring an overview over both persistent sources as well as transient events in the relevant phase space. Astro-COLIBRI's architecture comprises a RESTful API, a real-time database, a cloud-based alert system and a website as well as an app as clients for users. The structure of Astro-COLIBRI is optimized for performance and reliability and exploits concepts such as multi-index database queries, a global content delivery network (CDN), and direct data streams from the database to the clients to allow for a seemless user experience. Astro-COLIBRI evaluates incoming VOEvent messages of astronomical observations in real time, filters them by user specified criteria and puts them into their MWL and MM context. The clients provide a graphical representation with an easy to grasp summary of the relevant data to allow for the fast identification of interesting phenomena and provides an assessement of observing conditions at a large selection of observatories around the world.

The SuperNova Early Warning System (SNEWS) is a global network of neutrino experiments sensitive to supernova neutrinos. The goal of SNEWS is to provide the astronomical community with a prompt alert of an imminent Galactic core-collapse event. This will allow for complete multi-messenger observations of the supernova across the electromagnetic spectrum, in gravitational waves, and in neutrinos. A supernova event might also be visible to the naked eye a few hours or days after a prompt SNEWS alert.
This app uses the prompt alerts sent out by SNEWS to generate a Notification on iPhones using Apple’s Push Notification System. The app is meant to supplement the system established by SNEWS for the astronomical community and to be used by the general pubic interested in astronomy.
The app includes a Sky Map to locate the position in the sky of any reported supernova, Links to various astronomical websites related to supernovas, a public Message Board to share information among users and another public Message Board for posts from members of the SNEWS community.
A SuperNova event detectable by SNEWS is expected only every 10 years. So download this app, keep it on your device and await the next supernova.
