Journal ArticleDOI
Bar-driven Transport of Molecular Gas to Galactic Centers and Its Consequences
TL;DR: In this article, the authors studied the characteristics of molecular gas in the central regions of spiral galaxies on the basis of their CO(J = 1-0) imaging survey of 20 nearby spiral galaxies using the NRO and OVRO millimeter arrays.

TL;DR: In this article, Meidt et al. used Independent Component Analysis (ICA) to reveal the old stellar flux at 3.6μm and obtain stellar mass maps for more than 1600 galaxies available from the Spitzer Survey of Stellar Structure in Galaxies (S^4G).

TL;DR: In this paper, an independent component analysis (ICA) technique was used to separate statistically independent source distributions, maximizing the distinction in the [3.6]-[4.5] colors of the sources.

Structural properties of disk galaxies - I. The intrinsic equatorial ellipticity of bulges
Jairo Méndez-Abreu,Jairo Méndez-Abreu,Jairo Méndez-Abreu,J. A. L. Aguerri,Enrico Maria Corsini,E. Simonneau +5 more
TL;DR: In this paper, the structural parameters of a magnitude-limited sample of 148 unbarred S 0 − Sb galaxies were derived in order to study the correlations between bulges and disks, as well as the probability distribution function of the intrinsic equatorial ellipticity of bulges.
