2DTS aims to identify and classify transients discovered in active DESI fields, either by photometric observations with DECam or spectroscopic classification with DESI. This survey leverages both a system of spectroscopic follow-up through DESI and photometric follow-up through DECam.
This program is uncovering a population of relatively faint transients with peak magnitudes beyond 20.5 AB mag, and observing them with a cadence of roughly 3 days. These transients are discoverable by only a few wide-field instruments at present, and we hope to start to uncover a population of objects that will also be observable by Rubin LSST.
Our DECam program uses the SFFT difference imaging pipeline (Hu et al. 2022) to identify potential transients. Observations of ~100 sq. deg of sky will be observed. All sources discovered by DECam are being posted promptly to TNS by DESIRTbot. As a part of 2DTS, all PSN transients reported to TNS, are also being queued as ToOs for DESI, pending available fibers.
