COSMOGRAIL : the COSmological MOnitoring of GRAvItational Lenses XVI . Time delays for the quadruply imaged quasar DES J 0408 − 5354 with high-cadence photometric monitoring ?


We present time-delay measurements for the new quadruple imaged quasar DES J0408−5354, the first quadruple imaged quasar found in the Dark Energy Survey (DES). Our result is made possible by implementing a new observational strategy using almost daily observations with the MPIA 2.2 m telescope at La Silla observatory and deep exposures reaching a signal-to… (More)
