The incidence of the host galaxy light in the polarized emission of the blazars 1959+650 and 2201+044
We present a study carried out to determine variations in scales ranging from hours to days, both in the total flux and optical linear polarization in two blazars: 1959+650 and 2201+044. Both blazars are relatively nearby active galactic nuclei, so their host galaxies are well resolved, having accur...

We present a study carried out to determine variations in scales ranging from hours to days, both in the total flux and optical linear polarization in two blazars: 1959+650 and 2201+044.
