Description
The discovery of astrophysical neutrinos by IceCube has opened a new window onto the high-energy Universe. Despite significant progress, the origin of much of the observed emission remains unknown. I will briefly review the current multi-messenger landscape, highlighting recent progress and outstanding challenges in identifying cosmic particle accelerators. I will then discuss how engine-driven astrophysical transients can produce high-energy neutrinos, and how their multi-messenger signatures, particularly gravitational-wave triggers, can help identify these sources. Finally, I will highlight how the emerging high-energy neutrino sky offers new opportunities to probe fundamental physics. Together, these examples illustrate the potential of high-energy neutrinos to uncover cosmic accelerators and address fundamental questions in the coming era of multi-messenger astronomy.
