We have observed the OH (1720 MHz) line in five galactic SNRs with the VLA to measure their magnetic field strengths using the Zeeman effect. We detected all 12 of the bright (Sν > 200 mJy) OH (1720 MHz) masers previously detected by Frail et al. (1996) and Green et al. (1997) and measured significant magnetic fields (i.e. > 3σ) in ten of them. Assuming that the “thermal” Zeeman equation can be used to estimate | ~ B | for OH masers, our estimated fields range from 0.2 to 2 mG. These magnetic… CONTINUE READING
