5. Abstract: Astrophysical sources of very-high-energy (VHE) gamma-ray radiation
provide unique information about astrophysical particle acceleration and
cosmic-ray production. In particular, compact binary systems, composed
of a compact object (a neutron star or black hole) in orbit with a massive
stellar companion, provide an ideal environment for VHE gamma-ray production.
They are not only powerful particle accelerators, but they are excellent astrophysical
laboratories.
However, only a handful of binary systems have ever been observed in
VHE gamma rays. Partly, this is because VHE gamma-ray binaries appear
to be very rare, and part is due to observational bias. Most instruments operating
at TeV are pointed and must allocate time to observing many kinds
of objects. The High Altitude Water Cherenkov (HAWC) Observatory, on
the other hand, has high uptime (duty cycle >95%) and a wide field of view
(2 sr), making it well-suited for observing transient and time-varying sources
such as binaries.
In this talk, we present the most up-to-date results on three distinct gamma-ray
binary systems, namely, SS 433, LS 5039, and V4641 Sgr, produced using
1910 days of HAWC data.
