Out-Of-Focus Holography at the Green Bank Telescope
B. Nikolic, R. M. Prestage, D. S. Balser +2
We describe phase-retrieval holography measurements of the 100-m diameter Green Bank Telescope using astronomical sources and an astronomical receiver operating at a wavelength of…
The Electron Temperature Gradient in the Galactic Disk
C. Quireza, R. T. Rood, T. M. Bania +2
We derive the electron temperature gradient in the Galactic disk using a sample of HII regions that spans Galactocentric distances 0--17 kpc. The electron temperature was calculate…
The Chemical Evolution of Helium
Dana S. Balser
We report on measurements of the 4He abundance toward the outer Galaxy HII region S206 with the NRAO Green Bank telescope. Observations of hydrogen and helium radio recombination l…
Radio Recombination Lines in Galactic HII Regions
Cintia Quireza, Robert T. Rood, Dana S. Balser +1
We report radio recombination line (RRL) and continuum observations of a sample of 106 Galactic HII regions made with the NRAO 140 Foot radio telescope in Green Bank, WV. We believ…
