The present status of kinematical studies of intermediate-and late-type galaxies is reviewed.
The emphasis is on observations that result in extensive maps of velocity fields rather than …

Blue and near-infrared surface photometry of 15 barred spiral galaxies, combined with
results from photometric and kinematic studies of barred galaxies, reveals that:(1) early …

We performed a compilation of more than 1000 published spectra of H ii regions in spiral
galaxies. The oxygen and nitrogen abundances in each H ii region were recomputed in a …

Optical surface photometry from sky-limited IIIa-J plates of eight spiral galaxies observed in
the HI 21-cm line in the Westerbork telescope is presented. The following points are …

From a survey of all published rotation curves, it is found that in general a galaxy shows a
global spiral pattern either by maintaining nearly solid-body rotation throughout the region of …

Extranuclear clues to the origin and evolution of activity in galaxies ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically redirect to …

Observationally testable consequences of the hypothesis that galactic disks are confined
less by their self-gravity than that of some hot stellar component are sought. Theoretical and …

The behavior of the B-band Tully-Fisher relation with respect to the observational biases and
parameters uncertainties is studied from an almost complete sample of spiral galaxies …

Radio observations are reviewed which have been made with sufficient angular resolution
to provide some structural details of the radio continuum emission from the disks of normal …

This paper presents high-resolution X-ray observations with Chandra of NGC 4258 and
infers the nature of the so-called" anomalous arms" in this galaxy. The anomalous arms …
