我们提出的热模型适合11木星和3土星不规则卫星的测量的基础上，从WISE/NEOWISE数据集。我们的配合确认航天器测量的直径与现场观测（Himalia和Phoebe）的对象，并提供直径和12个以前未测量的对象，10木星和2土星不规则卫星。最适合的热模型光束参数是什么观察到的其他小天体在太阳系外，而可见光，W1和W2的光束跟踪以前建立在文献中的分类。测量的不规则卫星的反射率特性与木星特洛伊和希尔达人口相似，这意味着共同的起源。
We present thermal model fits for 11 Jovian and 3 Saturnian irregular satellites based on measurements from the WISE/NEOWISE data set. Our fits confirm spacecraft-measured diameters for the objects with in situ observations (Himalia and Phoebe) and provide diameters and albedo for 12 previously unmeasured objects, 10 Jovian and 2 Saturnian irregular satellites. The best-fit thermal model beaming parameters are comparable to what is observed for other small bodies in the outer solar system, while the visible, W1, and W2 albedos trace the taxonomic classifications previously established in the literature. Reflectance properties for the irregular satellites measured are similar to the Jovian Trojan and Hilda Populations, implying common origins.
