VLBA Observations of G5.89-0.39: OH masers and magnetic field structure
D. P. Stark, W. M. Goss, E. Churchwell +2
We present VLBA observations of 1667 MHz OH maser emission from the massive star formation region G5.89-0.39. The observations were phase referenced allowing the absolute positions…
The Formaldehyde Masers in Sgr B2: Very Long Baseline Array and Very Large Array Observations
Ian M. Hoffman, W. M. Goss, Patrick Palmer
Observations of two of the formaldehyde (H2CO) masers (A and D) in Sgr B2 using the VLBA+Y27 (resolution ~0.01") and the VLA (resolution ~9") are presented. The VLBA observations s…
The OH (1720 MHz) Supernova Remnant Masers in W44: MERLIN and VLBA Polarization Observations
Ian M. Hoffman, W. M. Goss, C. L. Brogan +1
Full-polarization MERLIN and VLBA observations of the 1720-MHz maser emission from the OH molecule in the supernova remnant W44 are presented. Zeeman splitting has been directly re…
The OH (1720 MHz) Supernova Remnant Masers in W28: MERLIN and VLBA Polarization Observations
Ian M. Hoffman, W. M. Goss, C. L. Brogan +1
Full-polarization MERLIN and VLBA observations of the 1720 MHz maser emission from the OH molecule in the supernova remnant W28 are presented. Zeeman splitting (|B| \approx 0.75 mG…
The Formaldehyde Masers in NGC 7538 and G29.96-0.02: VLBA, MERLIN, and VLA Observations
Ian M. Hoffman, W. M. Goss, Patrick Palmer +1
The 6 cm formaldehyde (H2CO) maser sources in the compact HII regions NGC 7538-IRS1 and G29.96-0.02 have been imaged at high resolution (beams < 50 mas). Using the VLBA and MERLIN,…
The Sizes of OH (1720 MHz) Supernova Remnant Masers: MERLIN and VLBA Observations of IC443
Ian M. Hoffman, W. M. Goss, C. L. Brogan +2
MERLIN and VLBA observations of the 1720 MHz maser emission from the OH molecule in the supernova remnant IC443 are presented. Based on MERLIN data with a resolution of 160 mas, th…
