Polarization microlensing in the quadruply imaged broad absorption line quasar H1413+117

摘要: We have obtained spectropolarimetric observations of the four images gravitationally lensed broad absorption line quasar H1413+117. The polarization microlensed image D is significantly different, both in continuum and lines, from A, which essentially unaffected by microlensing. suggest that scattered off two regions, spatially separated, producing roughly perpendicular polarizations. These results are compatible with a model polarized comes compact region located equatorial plane close to accretion disk non-microlensed an extended along polar axis.
