Title: Light Echoes of the Crab Supernova (SN 1054)

Abstract: We propose to continue our search for light echoes (LEs) from the Crab supernova, SN~1054. In previously granted NOAO time, we have discovered LEs of three ancient SNe in the LMC as well as from the historic SN events of Cas~A and Tycho[2, 3], which allowed their spectroscopic classification [6, 7, 10] and 3D spectroscopy [8, 9]. Most recently, we discovered light echoes of the mid-19th-century Great Eruption of $eta$~Carinae using CTIO 4m Mosaic images [11]. In previous semesters, we have monitored parts of the search area around the Crab supernova and other SNRs in the southern hemisphere. However, since the search area RA range overlapped with DES, we have not been able to fully cover the search area around the Crab supernova. We propose to continue our search for light echoes of the Crab Supernova. We propose to finish the observations of the southern half of its search area with DECam, which gives us a 10-15 fold improvement in efficiency over the retired CTIO-Mosaic camera, and the new Mosaic cameras at the KPNO 4m and WYIN. The study of scattered-light echoes from the Crab supernova will give us the opportunity to directly compare the original supernova and its current remnant including the pulsar, and in favorable cases (like Eta~Carinae and Cas~A), it provides a three-dimensional view of the event and/or a spectral time series.
