The History of Star Formation in Normal Late-Type Galaxies

Astrophysics and Space Science, 2001
We study the history of star formation of late-type galaxies using a multi-frequency analysis of a large sample of nearby objects spanning a wide range of morphological types and luminosities. The history of star formation and the total amount of gas of a galaxy are found to depend primarily on the total mass and only secondarily on the morphological ...

Dark Matter in Late-Type Galaxies

1992
The status of our knowledge of the extent and distribution of dark matter in late-type galaxies is reviewed. Recent attempts to alleviate the need for dark matter in late-type galaxies are examined, but none are found to give a satisfactory explanation. The mass distribution and shapes of dark matter halos are still known only poorly.

Cold Gas in Late-Type Galaxies

1992
In the last two decades a large number of spiral galaxies have been studied in the 21-cm line. These studies have revealed the density distribution and kinematics of HI and have provided the measurements of the total mass and the mass distribution in those systems.

Gaseous Halos of Late-Type Spiral Galaxies

Publications of the Astronomical Society of the Pacific, 1997
This article reviews the most recent observational results on disk-halo interactions in nearby galaxies. The implications of these results on our understanding of the structure of the interstellar medium (ISM) in our Galaxy and external spiral galaxies, with particular emphasis on the halo ISM, are discussed. Disk-halo interactions occur only above the

Dark Halos around Late-type galaxies

1985
In order to investigate the mass-to-light ratio in irregular Magellanic galaxies, a sample of 21 Sdm, Sm, Im objects, for which high-resolution velocity fields observed in 21 cm line are available in the literature, has been selected. Rotation curves, either taken from the authors or reconstructed from the original data and sometimes supplemented with ...

The formation of stellar halos in late-type galaxies

2007
Near–field observations may provide tight constraints - i.e. 'boundary conditions' - on any model of structure formation in the Universe. Detailed observational data have long been available for the Milky Way (e.g., Freeman and Bland-Hawthorn 2002) and have provided tight constraints on several Galaxy formation models (e.g.: Abadi et al.
