TL;DR: In this article, rotation curves of 19 galaxies from the H I Nearby Galaxy Survey (THINGS) were used to derive the geometric and dynamical parameters using H I data alone and the rotation curves were combined with 3.6 μm data from the Spitzer Infrared Nearby Galaxies Survey to construct mass models.

TL;DR: In this article, a sample of low-resolution 5-38um Spitzer IRS spectra of the inner few square kiloparsecs of 59 nearby galaxies spanning a large range of star formation properties is presented, and a robust method for decomposing mid-infrared galaxy spectra is described, and used to explore the behavior of PAH emission and the prevalence of silicate dust extinction.

TL;DR: Strong evidence of absorption of the spectrum of the quasar redwards of the Lyman α emission line (the Gunn–Peterson damping wing), as would be expected if a significant amount of the hydrogen in the intergalactic medium surrounding J1342 + 0928 is neutral, and a significant fraction of neutral hydrogen is derived, although the exact fraction depends on the modelling.

TL;DR: In this paper, the authors present evidence that bona fide disks and starburst systems occupy distinct regions in the gas mass versus star formation rate (SFR) plane, both for the integrated quantities and for the respective surface densities.
