Scientific Goals

The primary science goal of Watcher is to provide rapid follow up observations of gamma-ray burst (GRB) afterglows in support of the Swift and INTEGRAL satellites. Watcher provides coverage of the GRB afterglow emission in the optical band. This  allow us to obtain a more complete picture of the GRB emission in multiple wavelengths and thus, it helps us learning more of the physical processes involved in these extremely energetic explosions

Watcher is also used to monitor southern hemisphere gamma-ray blazars in conjunction with the H.E.S.S. collaboration. Complementary optical information is important for multi-wavelength studies of these astrophysical sources.

Watcher also monitors other transient events like magnetars, microlensing events, novae and supernovae in response to alerts from the Astronomer’s Telegram network and the GAIA mission, or upon request.
