74 MHz Discrete HII Absorption Regions Towards The Inner Galaxy
Michael E. Nord, P. A. Henning, R. J. Rand +2
At low radio frequencies (< 100 MHz), classical HII regions may become optically thick (optical depth > 1) and can be observed as discrete absorption regions against the Galactic n…
Evidence for a Weak Galactic Center Magnetic Field from Diffuse Low Frequency Nonthermal Radio Emission
T. N. LaRosa, C. L. Brogan, S. N. Shore +3
New low-frequency 74 and 330 MHz observations of the Galactic center (GC) region reveal the presence of a large-scale ($6\arcdeg\times 2\arcdeg$) diffuse source of nonthermal synch…
High-Resolution, Wide-Field Imaging of the Galactic Center Region at 330 MHz
Michael E. Nord, T. Joseph W. Lazio, Namir E. Kassim +4
We present a wide field, sub-arcminute resolution VLA image of the Galactic Center region at 330 MHz. With a resolution of ~ 7" X 12" and an RMS noise of 1.6 mJy/beam, this image r…
New Nonthermal Filaments at the Galactic Center: Are They Tracing a Globally Ordered Magnetic Field?
T. N. LaRosa, Michael E. Nord, T. Joseph W. Lazio +1
New high-resolution, wide-field 90 cm VLA observations of the Galactic Center region by Nord et al. have revealed twenty nonthermal filament (NTF) candidates. We report 6 cm polari…
Detection of Sagittarius A* at 330 MHz with the Very Large Array
Michael E. Nord, T. Joseph W. Lazio, Namir E. Kassim +2
We report the detection of Sagittarius A*, the radio source associated with our Galaxy's central massive black hole, at 330 MHz with the Very Large Array. Implications for the spec…
