Multi-wavelength XMM-Newton observations of blazars to be observed with IXPE

IXPE has opened a new window to the Universe by measuring X-ray polarization, already leading to significant progress in our understanding of particle acceleration in blazars. We propose to expand on this success with simultaneous OM/Epic observations of IXPE blazar targets. The proposed XMM-Newton exposures are needed to determine the spectral shape of the targets, thus to obtain robust spectro-polarimetric measurements. The requested data will be part of planned multiwavelength campaigns in radio, optical, and gamma-rays, enabling us to build simultaneous broaband datasets. Measurement of the mm-to-X-ray continuum spectra of blazars, coupled with X-ray polarization, will enable us to determine the mechanism and location of the X-rays, as well as test particle acceleration models in blazars.
