High-energy Neutrino Emission Associated with GWs from Binary Black Hole Mergers in AGN Accretion Discs

Understand

The search for multi-messenger signals of binary black hole (BBH) mergers is crucial to understanding the merger process of BBH and the relative astrophysical environment.

• Considering BBH mergers occurring in the active galactic nuclei (AGN) accretion disks, we focus on the accompanying high-energy neutrino production from the interaction between the jet launched by the post-merger remnant BH and disk materials.
• Particles can be accelerated by the shocks generated from the jet-disk interaction and subsequently interact with the disk gas and radiations to produce high-energy neutrinos through hadronic processes.
• We demonstrate that the identification of the high-energy neutrino signal from BBH merger in AGN disks is feasible.
