Milli-arcsecond scale rotation measure in the CSS quasars 0548+165 and 1524-136.

Abstract (from CDS):
Two Compact Steep-spectrum Sources (CSSs), 0548+165 and 1524-136, chosen from a list of CSSs with polarization percentages that decrease with decreasing frequency and high rotation measure values (RM>450rad/m2) on arcsecond scales, were observed with the VLBA at 4.9 and 8.4GHz. RM values up to ≃104rad/m2 were found in several regions along the jets in both sources. We suggest that a thin screen of magneto-ionic material with about 1kpc thickness is responsible for these high RMs. The observed depolarization may be due to beam depolarization and/or inhomogeneities in the magnetic field.
