Exploring the Potential of Multi-Detector Analyses for Core-Collapse Supernova Neutrino Detection

The core-collapse supernova (CCSN) SN1987A has been the first extragalactic transient source observed with neutrinos, and the 25 events detected by the neutrino telescopes running at that time marked the beginning of neutrino astronomy. Despite hundreds of CCSNs detected in the electromagnetic spectrum since 1987, neutrino telescopes could not perform another observation due to the far distances of the sources. It is thus of primary importance to optimize the detection channel of sensitive detectors in anticipation of a forthcoming Galactic CCSN. Beyond being used as an early warning of a close-by CCSN, neutrinos can provide unique information on the explosion mechanism, and can be used to probe neutrino oscillation in dense environments. In this contribution, we present the potential of multi-detector analysis to enhance the scientific outputs from the next close-by CCSN. Combining the expected light curves in neutrino detectors sensitive to different flavors, we study the constraints that could be set on the properties of the progenitor itself, such as its mass, as well as on the neutrino oscillation parameters. We also present the results of a triangulation algorithm using a prior source map in the definition of the the region of interest.
