The study of compact objects such as black holes and neutron stars is an important component of modern astrophysics. Recent detections of astrophysical neutrinos, gamma-rays, ultrahigh energy cosmic rays, and gravitational waves open up opportunities to study compact objects with multi-messengers. In this talk, we first review the latest progress in Astroparticle Physics, including some surprising puzzles revealed by new observations of neutrinos and gamma rays. We then demonstrate that the key to Multi-messenger Astrophysics is to understand and establish the link between the messengers. We show that high-energy particle propagation in the vicinity of compact objects may play an important role in connecting multi-wavelength observation and source physics.
