The award recognizes projects and research teams working to develop and disseminate free software, contributing to the construction of a crucial common good, and recognizing the production of free software as a contribution and a result of research. Free software under the Apache 2.0 license from the outset, Fink has continued to promote the values of free software as a solution to the technical challenges encountered in astronomy, as a necessary means for open science, and as a strong vector for scientific success. As part of the Platforms work package in MOTS, this approach proved efficient for example to keep simple the interoperability between Fink and the different actors, seamlessly integrating and deploying state-of-the-art scientific software to process and distribute openly astronomical alerts within the community.

Motivated by the enthusiastic feedback from all participants, we are already planning ahead for the 3rd edition. It will take place September 16-20, 2024 at Insitut Pascal: 

The International Astronomical Union (IAU) formed a new working group for professional-amateur relations in astronomy (for short, the Pro-Am WG) under its Executive Committee in 2021. The WG has the goal of promoting research collaborations, delivering workshops, and promoting and facilitating the integration of professional astronomers within amateur societies. A central initiative is the IAU Pro-Am Research Collaboration (PARC) that promotes and facilitates professional-amateur research collaborations in astronomy. A list of Pro-Am projects participating in this effort has now been published on the website of the WG. Continuing and extending our collaborations with amateur astronomers, Astro-COLIBRI is actively participating in this new global effort. 

Time domain astronomy is not limited to huge telescopes and professional astronomers. Everybody can participate in citizen science projects! To facilitate observations of transient phenomena we set up a collaboration between Astro-COLIBRI and the Unistellar citizen science program on "cosmic cataclysms".  Astro-COLIBRI now distributes alerts on interesting cosmic events detected by the ZTF observatory and that are accessible by the digital Unistellar telescopes. A dedicated link in the Astro-COLIBRI app allows to start immediate follow-up observations with the Unistellar eVscope or eQuinox telescopes. All crucial parameters will be set automatically. Data analysis and subsequent publications are handled in collaboration with the SETI Institute. See the official announcement for details.

Observations of transient astrophysical phenomena can now be triggered across the worldwide Unistellar network of citizen scientists via the Astro-COLIBRI platform.

ICRC ("International Cosmic Ray Conference") is the largest conference on astroparticle physics. This year it will bring together 1100+ participants in Nagoya, Japan. MOTS members are leading the following contributions and are presenting many others as co-authors:

Within the MOTS project, the Astro-COLIBRI team joined forces with the developers of "tilepy". The latter allows to calculate optimized follow-up schedules of multi-messenger events. Initally built for high-energy gamma-ray instruments, it is suited for telescopes of all sizes/FoV/locations/etc. 

Developed since a few years at IRFU / CEA Paris-Saclay, the MOTS participants at IRFU, LLR and external partners at IFAE/Barcelona were now ready to make the source code of tilepy public: Note: this is a very early release, a lot of things are still in a sub-optimal state, documentation is largely missing, etc. => work in progress, MOTS is only starting!

Even better: the Astro-COLIBRI team set up a cloud-based computing cluster and a public API at You can thus calculate follow-up schedules even without the need to install tilepy locally on your machine(s). Documentation is available at 

Still better: the tilepy API has been deeply integreate into the Astro-COLIBRI platform. You can thus visualize the follow-up schedules directly on you phone (Android and iOS) and on the web. In the example shown on the right, the observation plan is indicated by the yellow triangles. 

We are pleased to announce the 2nd Astro-COLIBRI multi-messenger astrophysics workshop that will take place from November 20 to November 24, 2023, at Institut Pascal at the Paris-Saclay University (France).

Building on the successful first workshop last year, we aim to discuss and develop a research agenda on interconnecting software tools for real-time multi-messenger astronomy. This international workshop provides a forum for leading scientists and young researchers to foster communication between developers and users with a wide range of expertise in the production and use of software tools that facilitate life in the rapidly evolving field of real-time multi-messenger astronomy. 

The first two days of the workshop will consist of invited and contributed talks to discuss the current hot topics, challenges, and opportunities in real-time multimessenger astronomy. Starting Wednesday, we will work together in small teams in a Hackathon-like event (“Sciathon”) prototyping and implementing new ideas developed during the workshop.

Participation is free of charge but the number of available places is limited. Application for participation is possible until August 31. The selected participants will be announced shortly after that. See details on the agenda on our website, where you can also register for the event: 

Project start: January 2023

The project has been funded by the french "Agency Nationale de Recherche" (ANR)! It started officially in January 2023 and runs over 4 years.
