Anomalous dust in late-type galaxies

EAS Publications Series, 2011
The last quarter century has seen a tremendous increase in quantitative information on the dust in galaxies. Yet, essential knowledge is still lacking. Recent results underline how determinations of dust mass and dust-to-gas ratio in galaxies are still beset by very considerable uncertainties.

Satellites of Late-Type Spiral Galaxies

EAS Publications Series, 2011
Using VIMOS (VLT) we carried out a spectroscopic survey around seven late-type spiral galaxies and we discovered 55 satellites. After obtaining the radial velocities and spatial distribution of the satellites, we analyze their properties.

Ionizing the Diffuse Interstellar Medium in Late-Type Galaxies

Astrophysics and Space Science, 2001
We show how the clumpy structure of the interstellar medium (ISM) both inside HII regions and in the diffuse component, permits the propagation of ionizing photons from OB stars on kiloparsec scales.

On the Luminosity Class of Late-Type Spiral Galaxies

Publications of the Astronomical Society of Japan, 1976
Abstract Correlations between the luminosity class in the DDO system and several observational quantities are investigated for late-type spiral galaxies. The luminosity class is found to be well correlated with maximum rotational velocity log Vm (correlation coefficient –0.83), Holmberg’s (1958) photometric radius log RH(–0.80), and ...
