A framework for multi-wavelength/multi-messenger analysis

threeML A framework for multi-wavelength/multi-messenger analysis for astronomy/astrophysics. Astrophysical sources are observed by different instruments at different wavelengths with an unprecedented quality. Putting all these data together to form a coherent view, however, is a very difficult task. Indeed, each instrument and data type has its own ad-hoc software and handling procedure, which present steep learning curves and do not talk to each other. The Multi-Mission Maximum Likelihood framework (3ML) provides a common high-level interface and model definition, which allows […]
