Polarimetric Properties of Event Horizon Telescope Targets from ALMA
Published 2021-01-01“…We also report the first unambiguous measurement of RM toward the M87 nucleus at millimeter wavelengths, which undergoes significant changes in magnitude and sign reversals on a one year timescale, spanning the range from −1.2 to 0.3 × 10 ^5 rad m ^−2 at 3 mm and −4.1 to 1.5 × 10 ^5 rad m ^−2 at 1.3 mm. Given this time variability, we argue that, unlike the case of Sgr A*, the RM in M87 does not provide an accurate estimate of the mass accretion rate onto the black hole. …”
