SUMMARY:Multi-messenger Astrophysics: Probing Compact Objects with Cos
 mic Particles\, Astronomy Colloquium\, Ke Fang\, UW Astronomy Departme
 nt
DESCRIPTION:The study of compact objects such as black holes and neutr
 on stars is an important component of modern astrophysics. Recent dete
 ctions of astrophysical neutrinos\, gamma-rays\, ultrahigh energy cosm
 ic rays\, and gravitational waves open up opportunities to study compa
 ct objects with multi-messengers. In this talk\, we first review the l
 atest progress in Astroparticle Physics\, including some surprising pu
 zzles revealed by new observations. We demonstrate that the key to Mul
 ti-messenger Astrophysics is to understand and establish the link betw
 een the messengers. We then illustrate how to reach this goal from bot
 h theoretical and observational perspectives. From the theoretical sid
 e\, we show that high-energy particle propagation in the vicinity of c
 ompact objects may play an important role in connecting multi-waveleng
 th observation and source physics. From the observational side\, we in
 vestigate analysis frameworks aiming to exploit data across multiple w
 avelengths and messengers.  <br>
