TL;DR: In this article, secure [NII] detections in two mm-bright, strongly lensed objects at high redshift, APM08279+5255 (z = 3.911) and MM18423+5938 (z=3.930), using the IRAM Plateau de Bure Interferometer were presented.

TL;DR: In this paper, the radio spectrum properties of I Zw 18, the dwarf galaxy with the lowest known nebular metal abundance in the local universe, were studied using high-resolution H alpha and short-wavelength radio continuum images.

TL;DR: In this article, the authors investigated the radial column density distribution in a sample of 9 galaxies taken from the THINGS survey, and used the HI data to probe the extent of the neutral (atomic) gas disks down to column densities of less than 0.1

TL;DR: In this article, the authors used the IRAM 30m radio telescope to detect CO (J=1-0) and (2-1) transitions in the CO (3-2) spectrum of the NGC3077 feature and found that the CO emission can be separated into at least 3 distinct complexes with equivalent radii between 250pc and 700pc and all well confined over a narrow range in velocity.
