Orion's Veil: Magnetic field strengths and other properties of a PDR in front of the Trapezium Cluster
T. H. Troland, W. M. Goss, C. L. Brogan +2
We present an analysis of physical conditions in the Orion Veil, a largely atomic PDR that lies just in front (about 2 pc) of the Trapezium stars. We have obtained 21 cm HI and 18…
VLA OH Zeeman Observations of the star forming region S88B
A. P. Sarma, C. L. Brogan, T. L. Bourke +2
We present observations of the Zeeman effect in OH thermal absorption main lines at 1665 and 1667 MHz taken with the Very Large Array (VLA) toward the star forming region S88B. The…
Self-Consistent Analysis of OH Zeeman Observations
R. M. Crutcher, N. Hakobian, T. H. Troland
Crutcher, Hakobian, and Troland (2009) used OH Zeeman observations of four nearby molecular dark clouds to show that the ratio of mass to magnetic flux was smaller in the ~0.1 pc c…
Optically Thick [O I] and [C II] Emission Towards NGC 6334 A
N. P. Abel, A. P. Sarma, T. H. Troland +1
This work focuses on [O I] and [C II] emission towards NGC 6334 A, an embedded H+ region/PDR only observable at infrared or longer wavelengths. A geometry where nearly all the emis…
A Magnetically-Supported Photodissociation Region in M17
E. W. Pellegrini, J. A. Baldwin, C. L. Brogan +6
The southwestern (SW) part of the Galactic H II region M17 contains an obscured ionization front that is most easily seen at infrared and radio wavelengths. It is nearly edge-on, t…
Sensitive VLBI Studies of the OH Megamaser Emission from IRAS 17208-0014
E. Momjian, J. D. Romney, C. L. Carilli +1
We present phase-referenced VLBI results on the radio continuum and the OH 18 cm megamaser emission from the Ultra-Luminous Infrared Galaxy, IRAS 17208--0014. The observations were…
