Query: NEOWISE: Observations of the Irregular Satellites of Jupiter and Saturn   We present thermal model fits for 11 Jovian and 3 Saturnian irregular
satellites based on measurements from the WISE/NEOWISE dataset. 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.
