Magnetic fields and ionized gas in nearby late type galaxies ∗
Aims. In order to analyze the importance of the star formation rate in generating and amplifying magnetic fields in the interstellar medium we perform a deep continuum polarization study of three angularly large, late type spiral galaxies. Methods. We obtained deep total power and polarization maps at 4.85 GHz of NGC 4236, NGC 4656 and IC 2574 using the 100-m Effelsberg radio telescope. This wa...
متن کاملThe rotation curves shapes of late-type dwarf galaxies
We present rotation curves derived from H i observations for a sample of 62 galaxies that have been observed as part of the Westerbork H i Survey of Spiral and Irregular Galaxies (WHISP) project. These rotation curves have been derived by interactively fitting model data cubes to the observed cubes. This procedure takes the rotation curve shape, the H i distribution, the inclination, and the si...
متن کاملNearby early – type galaxies with ionized gas . II . Line - strength indices for 18 additional galaxies ⋆
Rampazzo et al. 2005 (hereafter Paper I) presented a data-set of line-strength indices for 50 early-type galaxies in the nearby Universe. The galaxy sample is biased toward galaxies showing emission lines, located in environments corresponding to a broad range of local galaxy densities, although predominantly in low density environments. The present addendum to Paper I enlarges the above data-s...
متن کاملOld Stellar Populations in Nearby Dwarf Galaxies
What can we learn from the somewhat arduous study of old stellar populations in nearby galaxies? Unless the nearby universe is subtly anomalous, it should contain a relatively normal selection of galaxies whose histories are representative of field galaxies in general throughout the Universe. We can therefore take advantage of our ability to resolve local galaxies into individual stars to direc...
متن کاملTidal dwarf galaxies in the nearby Universe
We present a statistical observational study of the tidal dwarf (TD) population in the nearby Universe by exploiting a large, homogeneous catalogue of galaxy mergers compiled from the Sloan Digital Sky Survey. 95% of TD-producing mergers involve two spiral progenitors (typically both in the blue cloud), while most remaining systems have at least one spiral progenitor. The fraction of TD-produci...
