DARTS: Dual-channel Automatic Rapid Transient Spectograph

What is DARTS?

DARTS is a low-resolution spectrograph for transient astrophysics at Lick Observatory.

Astrophysical transients like supernovae have a broad range of applications from the discovery of the accelerated expansion of the Universe to counterparts to gravitational wave sources. There are a wide variety of transients, and spectra are key to understanding them.

New surveys are discovering >10,000 transients each year with the discovery rate doubling every year. But the number of spectra has stagnated because of the lack of spectroscopic resources, where only 10% of discoveries ever have a spectrum. DARTS will solve this problem.

The combination of DARTS and APF will be the largest-aperture robotic telescope with a low-resolution spectrograph. With queue scheduling, we can quickly observe new discoveries, get nightly observations of interesting targets, and easily time observations with other resources.
