New 325 MHz observations of H II galaxies - The mechanisms that shape the unusual radio spectra
The B array of the VLA has observed a sample of seven H II galaxies at 325 and 1489 MHz; the radio continuum spectra thus obtained exhibit a wide variety of spectral shapes, but four show a significant flattening toward ...
An H I absorption survey of M31 and M33 - The mixture of warm and cool phases in the interstellar media of spiral galaxies
The VLA in A-array is used to survey the nearby spiral galaxies M31 and M33 in the 21-cm line in order to measure absorption by the H I toward background continuum sources. Spectral line cubes with rms noise less than 1.2 ...
