▪ Abstract The Universe is in transition. At early times, galactic evolution was dominated by
hierarchical clustering and merging, processes that are violent and rapid. In the far future …

We review the physical properties of nearby, relatively luminous galaxies, using results from
newly available massive data sets together with more detailed observations. First, we …

We identify stellar structures in the PHANGS sample of 74 nearby galaxies and construct
morphological masks of sub-galactic environments based on Spitzer 3.6 μm images. At the …

We use a homogeneous sample of about 1100 optical and radio rotation curves (RCs) and
relative surface photometry to investigate the main mass structure properties of spirals, over …

We investigate the relationships between the characteristic oxygen abundance, the radial
abundance gradient, and the macroscopic properties of spiral galaxies by examining the …

ABSTRACT The Spitzer Survey of Stellar Structure in Galaxies (S 4 G) is the largest
available database of deep, homogeneous middle-infrared (mid-IR) images of galaxies of all …

ABSTRACT The Spitzer Survey of Stellar Structure in Galaxies () is an Exploration Science
Legacy Program approved for the Spitzer post–cryogenic mission. It is a volume-, magnitude …

Some 30% of disc galaxies have a pronounced central bar features in the disc plane and
many more have weaker features of a similar kind. Kinematic data indicate that the bar …

Kenneth Lang's classic work Astrophysical Formulae.(Vol. I and II) is now available as soft
cover edition in a set. This volume is a reference source of fundamental formulae in physics …

Isolated barred galaxies evolve by redistributing their angular momentum, which, emitted by
material in the inner disc at resonance with the bar, can be absorbed by resonant material in …
