TL;DR: In this paper, the fractal and scale-free nature of interstellar CO clouds with power indices that are independent of distance has been investigated and the results are αL = 1 + D and αM = 1+ D/κ for interstellar fractal dimension D = 2.3 ± 0.3 and a value of κ in the range 2.4-3.7.

TL;DR: In this article, the authors studied the properties of the bulges formed by the supernova feedback in the early universe and found that they are all thick, slowly rotating, and have a high Sersic index, like classical bulges.

TL;DR: In this article, a modified version of the proposal by Maloney and Fleck (1988) that the correlation is due to virialized internal motions and a uniform external pressure is addressed.

TL;DR: The LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The HI Nearby Galaxy Survey) survey as discussed by the authors is a multi-wavelength survey of 37 Dwarf Irregular and 4 Blue Compact Dwarf galaxies that is centered around HI-line data obtained with the National Radio Astronomy Observatory (NRAO) Very Large Array (VLA) for determining what drives star formation in dwarf galaxies.

TL;DR: The star formation rate in the central molecular zone (CMZ) of the Milky Way is lower by a factor of ≥ 10 than expected for the substantial amount of dense gas it contains, which challenges current star formation theories as discussed by the authors.
