TL;DR: In this article, neutral hydrogen synthesis mapping of NGC 4532 and DDO 137 is used to determine rotation curves for each of the galaxies and to resolve the structure and kinematics of three distinct HI concentrations embedded in an extended envelope of diffuse HI discovered in earlier Arecibo studies of the system.

TL;DR: In this article, the relation between polycyclic aromatic hydrocarbons (PAH) emission at 8 mu m and far-infrared emission from hot dust grains at 24 and 250 mu m in the nearby spiral galaxies NGC 2403 and M83 using data from the Spitzer Space Telescope and Herschel Space Observatory was examined.

TL;DR: In this article, H I synthesis array mapping and CCD photometry in B and R for MCG+00-32-16 was presented, where the H I disk is rotating in such a way that the side of the galaxy closer to the sight-line to the quasar has the larger velocity difference from the absorber.

TL;DR: In this paper, the nearest void in the distribution of galaxies, in a direction perpendicular to the fundamental plane of the Local Supercluster, has been sampled in the neutral hydrogen spectral line for low-mass gas clouds or H I-rich dwarf galaxies.

TL;DR: In this article, the authors present HI synthesis array mapping and CCD photometry in B and R for MCG+00-32-16 and HI 1225+01.
