A Complete Catalogue of Dusty Supernova Remnants
  We search for far-infrared (FIR) counterparts of known supernova remnants
(SNRs) in the Galactic plane (360 degrees in longitude and b = +/- 1 deg ) at
70 - 500 micron with Herschel. We detect dust signatures in 39 SNRs out of 190,
made up of 13 core-collapse supernovae (CCSNe), including 4 Pulsar Wind Nebulae
(PWNe), and 2 Type Ia SNe. A further 24 FIR detected SNRs have unknown types.
We confirm the FIR detection of ejecta dust within G350.1-0.3, adding to the
known sample of ~10 SNRs containing ejecta dust. We discover dust features at
the location of a radio core at the centre of G351.2+0.1, indicating FIR
emission coincident with a possible Crab-like compact object, with dust
temperature and mass of Td = 45.8 K and Md = 0.18 solar mass, similar to the
PWN G54.1+0.3. We show that the detection rate is higher among young SNRs. We
produce dust temperature maps of 11 SNRs and mass maps of those with distance
estimates, finding dust at temperatures 15 < Td < 40 K. If the dust is heated
by shock interactions the shocked gas must be relatively cool and/or have a low
density to explain the observed low grain temperatures.
