A Unique Messenger to Probe Active Galactic Nuclei:
High-Energy Neutrinos
Astro2020 Decadal Survey White Paper
The detection of astrophysical neutrinos by IceCube and the evidence for neutrino emission from a blazar offer exciting opportunities for the study of high-energy neutrinos and photons from AGN in the coming decade. We advocate for a multi-messenger approach that combines high-energy neutrino observations performed by telescopes that will come online in the next decade, and multi-wavelength EM observations by existing and future instruments, with an emphasis on soft X-ray to VHE gamma-ray coverage. The unique capabilities of these instruments combined promise to solve several long-standing issues in our understanding of AGN, the most powerful and persistent cosmic accelerators.
The white paper has now been submitted to the Astro2020 decadal survey. You can find the submitted version in the arXiv.
