论文摘要
我们在70-500微米的Herschel中搜索已知超新星残留物(SNR)的远红外(FIR)对应物(经度的360度,B = +/- 1度)。我们在190个SNR中检测到尘埃标志,其中包括13个核心折叠超新星(CCSNE),其中包括4个脉冲星风星(PWNE)和2种IA型SNE。另外24个检测到的SNR具有未知类型。我们确认了G350.1-0.3中喷射灰尘的FIR检测,从而增加了已知的含有弹出粉尘的〜10个SNR的样品。我们在G351.2+0.1的中心的无线电芯位置发现了灰尘特征,表明FIR发射与可能的蟹状的紧凑物体一致,灰尘温度和TD = 45.8 K和MD = 0.18太阳能块,类似于PWN G54.1+0.3。我们表明,年轻SNR的检测率更高。我们产生11个SNR的灰尘温度图和具有距离估计值的质量图,在温度下15 <td <40 k找到灰尘。如果冲击相互作用加热灰尘,则冲击气体必须相对较酷,并且/或具有低密度来解释观察到的低晶粒温度。
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.
