74 MHz Discrete HII Absorption Regions Towards The Inner Galaxy (2006)
Nord, Michael E., Henning, P. A., Rand, R. J., Lazio, T. Joseph W., Kassim, Namir E.
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 nonthermal...
High-Resolution, Wide-Field Imaging of the Galactic Center Region at 330 MHz (2004)
Nord, Michael E., Lazio, T. Joseph W., Kassim, Namir E., Hyman, S. D., LaRosa, T. N., Brogan, C., ...
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 represents a...
LaRosa, T. N., Nord, Michael E., Lazio, T. Joseph W., Kassim, Namir E.
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 polarization observations...
Detection of Sagittarius A* at 330 MHz with the Very Large Array (2003)
Nord, Michael E., Lazio, T. Joseph W., Kassim, Namir E., Goss, W. M., Duric, N.
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 spectrum and emission...
