OH masers associated with bipolar outflow in ON1
Multi-Element Radio-Linked Interferometer Network polarization measurements of the OH 18-cm masers in ON1 are presented. OH maser emission is detected in all four ground state lines. The bulk of the masers lie in an elongated distribution covering 2 arcsec at position angle 130°, near the southern e...
