The AMIGA sample of isolated galaxies. XIV. Disc breaks and interactions through ultra-deep optical imaging
P. M. Sánchez-Alarcón, J. Román, J. H. Knapen +10
In the standard cosmological model of galaxy evolution, mergers and interactions play a fundamental role in shaping galaxies. Galaxies that are currently isolated are thus interest…
Star Formation in Outer Rings of S0 galaxies. V. UGC 4599 -- an S0 with gas probably accreted from a filament
O. Sil'chenko, A. Moiseev, D. Oparin +2
Though S0 galaxies are usually thought to be `red and dead', they often demonstrate weak star formation organised in ring structures and located in their outer disks. We try to cla…
Cloud-scale Radio Surveys of Star Formation and Feedback in Triangulum Galaxy M 33: VLA Observations
F. S. Tabatabaei, W. Cotton, E. Schinnerer +11
Studying the interplay between massive star formation and the interstellar medium (ISM) is paramount to understand the evolution of galaxies. Radio continuum (RC) emission serves a…
Discovery of ultra-compact nuclear rings in three spiral galaxies
S. Comerón, J. H. Knapen, J. E. Beckman +1
Ring-shaped morphologies of nuclear star-forming regions within the central 40-200 pc of disk galaxies have been barely resolved so far in three composite Sy2 nuclei, the Sy2 Circi…
Statistics and properties of HII regions in a sample of grand design galaxies I. Luminosity functions
M. Rozas, J. E. Beckman, J. H. Knapen
We present new high quality continuum-subtracted H alpha images of the grand-design galaxies NGC 157, NGC 3631, NGC 6764 and NGC 6951. We have determined the positions, angular siz…
The extinction by dust in the outer parts of spiral galaxies
R. F. Peletier, E. A. Valentijn, A. F. M. Moorwood +3
To investigate the distribution of dust in Sb and Sc galaxies we have analyzed near-infrared and optical surface photometry for an unbiased sample of 37 galaxies. Since light in th…
