Astro-COLIBRI is a multimessenger alert aggregation and visualization platform designed to support rapid follow-up of transient astronomical events, integrating data streams from electromagnetic, neutrino, and gravitational-wave observatories. The project connects observatories, surveys, and research institutions to enable coordinated responses to events reported by facilities such as Fermi Gamma-ray Space Telescope, Swift Observatory, IceCube Neutrino Observatory, LIGO Scientific Collaboration, and Virgo (detector), while interfacing with archival resources from Hubble Space Telescope, Chandra X-ray Observatory, XMM-Newton, and Very Large Telescope. The platform is used by professional consortia, survey teams, and time-domain networks including Zwicky Transient Facility, Pan-STARRS, Las Cumbres Observatory, and European Southern Observatory.

Overview

Astro-COLIBRI aggregates alerts from projects like Zwicky Transient Facility, All-Sky Automated Survey for Supernovae, Gaia (spacecraft), Fermi Gamma-ray Space Telescope, Swift Observatory, and IceCube Neutrino Observatory to provide a unified view compatible with systems from LIGO Scientific Collaboration, Virgo (detector), KAGRA, and ANTARES. The interface supports cross-matching with catalogs such as Sloan Digital Sky Survey, Two Micron All Sky Survey, Pan-STARRS, Gaia (spacecraft), and SIMBAD, and links to spectroscopic resources like Sloan Digital Sky Survey-III, European Southern Observatory, Keck Observatory, and Gemini Observatory. Users include teams from Max Planck Society, Harvard-Smithsonian Center for Astrophysics, California Institute of Technology, Massachusetts Institute of Technology, and European Space Agency.

History and Development

Development began in the context of multimessenger efforts coordinated after detections like those announced by LIGO Scientific Collaboration and IceCube Neutrino Observatory, influenced by campaigns such as the follow-up to GW170817, TXS 0506+056, and GRB 170817A. Early contributors included researchers from Max Planck Institute for Astrophysics, University of Geneva, University of Amsterdam, University of California, Berkeley, and University College London. Funding and support have involved organizations such as European Space Agency, National Science Foundation, Deutsche Forschungsgemeinschaft, and private consortia including Simons Foundation. Software practices draw on tools and communities like Astropy, HEASARC, VOEvent, AMON, and Zooniverse.

Mission and Objectives

Astro-COLIBRI aims to accelerate discovery by providing real-time alert ingestion, context enrichment, and follow-up coordination for transients identified by instruments such as Fermi Gamma-ray Space Telescope, Swift Observatory, INTEGRAL, and MAXI. Objectives include enabling rapid localization for facilities like Very Large Array, Atacama Large Millimeter/submillimeter Array, Subaru Telescope, and Square Kilometre Array, streamlining priority-setting for programs at European Southern Observatory, Keck Observatory, Gemini Observatory, and robotic networks such as Las Cumbres Observatory. The platform supports science goals relevant to teams from Harvard-Smithsonian Center for Astrophysics, Space Telescope Science Institute, Jet Propulsion Laboratory, and CERN.

Architecture and Technology

The architecture integrates alert streams using protocols like VOEvent and APIs used by services such as NASA Goddard Space Flight Center, HEASARC, and GCN (Gamma-ray Coordinates Network), employing back-end stacks influenced by projects at CERN, Amazon Web Services, and development ecosystems like GitHub and Docker. Cross-matching uses catalogs including Sloan Digital Sky Survey, Two Micron All Sky Survey, Pan-STARRS, Gaia (spacecraft), SIMBAD, and tools from Astropy and Topcat. Visualization and mobile delivery support coordinate transformation and localization regions used by LIGO Scientific Collaboration, Virgo (detector), and KAGRA, while authentication and access models reflect practices at European Southern Observatory and NASA. Alert filtering and broker features reflect designs from ANTARES (project), AMON, and Zwicky Transient Facility broker efforts.

Scientific Contributions and Use Cases

Astro-COLIBRI has been applied in campaigns following high-profile events such as alerts from LIGO Scientific Collaboration for compact-object mergers, neutrino candidates from IceCube Neutrino Observatory linked to blazars like TXS 0506+056, and gamma-ray bursts reported by Fermi Gamma-ray Space Telescope and Swift Observatory. The platform supports multiwavelength follow-up by observatories including Hubble Space Telescope, Chandra X-ray Observatory, Very Large Telescope, Keck Observatory, Atacama Large Millimeter/submillimeter Array, and Very Large Array, aiding teams at institutions like Harvard-Smithsonian Center for Astrophysics, California Institute of Technology, and Max Planck Society. Use cases include rapid alert triage for survey projects such as Zwicky Transient Facility, Pan-STARRS, LSST, and archival cross-matching with Sloan Digital Sky Survey and Two Micron All Sky Survey for source classification by groups at University of Cambridge, Princeton University, and University of Chicago.

Collaborations and Partnerships

Astro-COLIBRI collaborates with major facilities and consortia including LIGO Scientific Collaboration, Virgo (detector), KAGRA, IceCube Neutrino Observatory, Fermi Gamma-ray Space Telescope, Swift Observatory, Zwicky Transient Facility, Pan-STARRS, Las Cumbres Observatory, European Southern Observatory, Keck Observatory, Gemini Observatory, Atacama Large Millimeter/submillimeter Array, Very Large Array, Hubble Space Telescope, Chandra X-ray Observatory, NASA, European Space Agency, National Science Foundation, Max Planck Society, Simons Foundation, and software communities like Astropy and VOEvent. Partnerships extend to academic groups at Harvard University, Massachusetts Institute of Technology, California Institute of Technology, University of Oxford, University of Tokyo, University of Amsterdam, and University of Melbourne.

Access, Data Products, and User Community

Access channels include web clients, mobile apps, and APIs compatible with services such as GCN (Gamma-ray Coordinates Network), VOEvent, and institutional archives at HEASARC, European Space Agency, and Mikulski Archive for Space Telescopes. Data products are cross-matched catalogs and enriched alert packets used by researchers at Harvard-Smithsonian Center for Astrophysics, Max Planck Institute for Astrophysics, California Institute of Technology, Princeton University, University of Cambridge, and citizen-science collaborators via Zooniverse. The user community comprises scientists from LIGO Scientific Collaboration, IceCube Neutrino Observatory, Fermi Gamma-ray Space Telescope, Swift Observatory, European Southern Observatory, Keck Observatory, survey teams from Zwicky Transient Facility and Pan-STARRS, and educators linked to Space Telescope Science Institute.
