GAMMA Science Case
The astrophysical motivation for building a student-led gamma-ray transient constellation
Synergies with Next-Generation Observatories
The 2030s will see an unprecedented convergence of multi-messenger facilities. CAPIBARA-GAMMA is timed to be the high-energy sentinel for this network: providing rapid electromagnetic counterpart alerts in X-ray and gamma-ray, guiding follow-up by telescopes that cannot scan the whole sky.
Planned synergies include rapid and precise localisation of short GRB counterparts to neutron star mergers detected by LIGO, the Einstein Telescope, and LISA; triggering follow-up by THESEUS, NewAthena, and CTAO; and identifying high-energy electromagnetic counterparts to IceCube and KM3NeT neutrino alerts.

Key Concepts
What are Gamma-Ray Bursts?
Gamma-ray bursts are the most luminous electromagnetic events known. They are short-lived — lasting milliseconds to minutes — and release the equivalent energy of the Sun's total lifetime output in moments. They are believed to arise from the collapse of massive stars (long GRBs) or the merger of two compact objects like neutron stars (short GRBs), which also produce gravitational waves.
What is Multi-Messenger Astronomy?
Multi-messenger astronomy is the coordinated observation of astronomical events across multiple signal channels: gravitational waves, neutrinos, cosmic rays, and the full electromagnetic spectrum. Reconstructing the source through independent messengers provides richer physical information than any single channel alone.
