| Abstract: |
Over the last ten years, astrophysics has seen significant progress in multi-messenger observations, including more and more sources of very-high-energy (VHE)
gamma rays being detected, gravitational wave detections, and the identification of
astrophysical VHE neutrinos. To enhance joint analyses and interoperability among
instruments, the VHE astrophysics community focused on refining and opening data
formats and analysis software. Gammapy, a Python-based open-source package developed initially for VHE gamma-ray astronomy and now adopted by the Cherenkov
Telescope Array (CTA) observatory, has expanded to support multi-wavelength (MWL)
and multi-messenger (MM) astrophysics. It integrates with various instruments, including H.E.S.S., VERITAS, MAGIC, Fermi-LAT, and HAWC, while also being tested with
X-ray and neutrino data. This library operates based on open FITS-based formats for
science-ready high-level data. In parallel, 11 astroparticle experiments collaborated to
form the Very-high-energy Open Data Format (VODF) initiative, aiming to set standards from high-level data to astrophysical products and catalogs. This contribution
discusses efforts within the VHE gamma-ray and neutrino community to enhance data
interoperability among instruments in alignment with open science commitments, focusing on the VODF initiative and the Gammapy project, their current status and future enhancements. |
