TL;DR: In this article, the authors presented an atlas and classifications of S4G galaxies in the Comprehensive de Vaucouleurs revised Hubble-Sandage (CVRHS) system.
Journal ArticleDOI
The Hα Galaxy Survey ⋆ I. The galaxy sample, Hα narrow-band observations and star formation parameters for 334 galaxies
P. A. James,N. S. Shane,John E. Beckman,A. Cardwell,Chris A. Collins,Jason Etherton,R. S. de Jong,Kambiz Fathi,J. H. Knapen,Reynier Peletier,Susan M. Percival,Don Pollacco,Marc S. Seigar,S. Stedman,Iain A. Steele +14 more
TL;DR: In this article, a large sample of nearby galaxies is used to quantify the star formation activity in the local Universe, which consists of 334 galaxies across all Hubble types from S 0/a to Im and with recession velocities of between 0 and 3000 km s 1.
Journal ArticleDOI
The central region in m100 - observations and modeling
TL;DR: In this article, high-resolution observations of the central region in the late-type spiral galaxy M100 (NGC 4321) supplemented by three-dimensional numerical modeling of stellar and gas dynamics, including star formation, are presented.
Journal ArticleDOI

Erroz-Ferrer,Jarkko Laine,S. Comeron +28 more
TL;DR: In this paper, Meidt et al. used Independent Component Analysis (ICA) to reveal the old stellar flux at 3.6$\mu m$ and obtain stellar mass maps for more than 1600 galaxies available from the Spitzer Survey of Stellar Structure in Galaxies (S$^{4}$G).
Journal ArticleDOI

Philip A. James,N. S. Shane,J. E. Beckman,A. Cardwell,Chris A. Collins,Jason Etherton,R. S. de Jong,Kambiz Fathi,J. H. Knapen,Reynier Peletier,Susan M. Percival,Don Pollacco,Marc S. Seigar,S. Stedman,Iain A. Steele +14 more
TL;DR: In this article, a large sample of nearby galaxies is used to quantify the star formation activity in the local Universe, which consists of 334 galaxies across all Hubble types from S 0/a to Im and with recession velocities of between 0 and 3000 km/s.
