Description
With the advent of the IXPE (Imaging X-ray Polarimetry Explorer) satellite
expected for launch in 2021, the study of the
X-ray polarization properties of several bright nearby sources
will become possible. Blazars are obvious candidates for X-ray
polarization observations.
For instance, a high degree of X-ray polarization is expected from
high-peaked blazars (HBL) because synchrotron radiation in an ordered
magnetic field
is naturally polarized. Moreover, X-ray polarization observations
have the potential of discriminating between different scenarios for the
origin
of the X-ray emission in low peaked blazars (LBL) objects.
In this talk, we discuss the perspectives of IXPE observations of blazars,
focusing on polarization modeling of different classes of BL Lac objects.
