Query: The Polarization Properties of Inverse Compton Emission and Implications
  for Blazar Observations with the GEMS X-Ray Polarimeter   NASA's Small Explorer Mission GEMS (Gravity and Extreme Magnetism SMEX),
scheduled for launch in 2014, will have the sensitivity to detect and measure
the linear polarization properties of the 0.5 keV and 2-10 keV X-ray emission
of a considerable number of galactic and extragalactic sources. The prospect of
sensitive X-ray polarimetry justifies a closer look at the polarization
properties of the basic emission mechanisms. In this paper, we present
analytical and numerical calculations of the linear polarization properties of
inverse Compton scattered radiation. We describe a generally applicable
formalism that can be used to numerically compute the polarization properties
in the Thomson and Klein-Nishina regimes. We use the code to perform for the
first time a detailed comparison of numerical results and the earlier
analytical results derived by Bonometto et al. (1970) for scatterings in the
Thomson regime. Furthermore, we use the numerical formalism to scrutinize the
polarization properties of synchrotron self-Compton emission, and of inverse
Compton radiation emitted in the Klein-Nishina regime. We conclude with a
discussion of the scientific potential of future GEMS observations of blazars.
The GEMS mission will be able to confirm the synchrotron origin of the
low-energy emission component from high frequency peaked BL Lac objects.
Furthermore, the observations have the potential to decide between a
synchrotron self-Compton and external-Compton origin of the high-energy
emission component from flat spectrum radio quasars and low frequency peaked BL
Lac objects.
