5th Astro-COLIBRI multi-messenger astrophysics workshop

12 oct. 2026, 00:00 → 16 oct. 2026, 18:00 Europe/Paris

Amphitheater + Cathedrale+ Offices (Institut Pascal)

Fabian Schussler (IRFU / CEA Paris-Saclay), Patrick Reichherzer (University of Oxford), Ilja Jaroschewski (CEA - IRFU - DPhP), Bernardo Cornejo Avila (CEA IRFU/DPhP), Sofia Bisero (IRFU / CEA Paris-Saclay)

The key objective of this workshop is 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 covering a large range of expertise in the production and use of software tools that make life easier in the rapidly evolving domain of real-time multi-messenger astronomy.

The workshop will also be a F2F meeting of members of the working group on realtime multi-messenger observations within the ACME project.

7 The Pierre Auger Observatory in ACME: Expansion of Open Data Access and Development of Real-Time Multi-Messenger Alert Capabilities

The Pierre Auger Observatory, the world’s largest extensive air-shower detector array, is optimized for the measurement of ultra-high-energy cosmic rays (UHECRs) and also provides sensitivity to ultra-high-energy neutrinos via detection of neutrino-induced air showers. Since the start of full operations in 2004, the Observatory has delivered key results in UHECR physics, including constraints on the energy spectrum, mass composition, and arrival direction anisotropies, and has become an important component of the multi-messenger astrophysics landscape.

The Observatory is integrated within the Astrophysical Center for Multi-messenger in Europe (ACME), an infrastructure initiative focused on enabling interoperable data access and enhancing coordination between major astroparticle facilities for time-domain and multi-messenger studies.

Within the ACME framework, the Pierre Auger Collaboration is currently expanding its open data strategy by increasing the accessibility of its archival datasets and developing capabilities for near-real-time analysis. In particular, ongoing developments target the implementation of a real-time alert system based on the identification of neutrino-induced and other highly inclined air-shower signatures, with the goal of enabling rapid multi-wavelength and multi-messenger follow-up observations.

This contribution will present the current status of ACME-related activities within the Pierre Auger Observatory, with emphasis on the extension of the public data infrastructure and the development and commissioning of the real-time alert pipeline.

14 SCIMMA and its role in Time-Domain Astrophysics

Within minutes of a neutron-star merger, a gravitational-wave trigger, a gamma-ray burst, and an optical kilonova surface in separate data streams — and the discovery exists only if those streams can be joined fast enough to point telescopes before the source fades. SCIMMA, the Scalable Cyberinfrastructure for Multi-Messenger Astrophysics, builds and operates that connective layer; its Kafka-based Hopskotch platform already distributes LIGO, Virgo, and KAGRA alerts to follow-up teams worldwide. The scale is about to grow by orders of magnitude. The Schmidt Sciences Observatory System alone brings three facilities online this decade: the all-sky Argus Array on second cadences, the Deep Synoptic Array localizing thousands of fast radio bursts per year, and the Lazuli space telescope responding to targets of opportunity in under four hours. These arrive alongside Rubin's ten million alerts per night, the gravitational-wave and neutrino networks, Euclid's deep imaging, and the Sino-French SVOM's real-time gamma-ray burst triggers. None is useful in isolation; the physics lives in the coincidences between them. I will describe SCIMMA as an end-to-end stack: Hopskotch routes the alerts, HERMES gives people and machines access to the streams, DASH classifies supernova spectra in real time, BLAST characterizes host galaxies, and HEROIC coordinates follow-up across facilities. With the AI methods of the NSF-Simons SkAI Institute and platforms such as Astro-COLIBRI, these tools turn heterogeneous streams into discoveries within seconds. The telescopes of the next decade are being built now; the infrastructure that lets them act as on observatory has to be built alongside them.
