The ring images presented here are part of a larger William Herschel Telescope (WHT) imaging survey (1999 and 2000) conducted to characterize the nuclear and circumnuclear morphology in nearby galaxies (Paper I, Knapen et al., 2006A&A...448..489K). (2 data files).

We estimate the current extinction-corrected Hα star formation rate (SFR) of the different morphological components that shape galaxies (bulges, bars, and disks). We use a multicomponent photometric decomposition based on Sloan Digital Sky Survey imaging to Calar Alto Legacy Integral Field Area Integral Field Spectroscopy (IFS) datacubes for a

We present H I 21 cm observations of the grand design spiral galaxy NGC 4321, as obtained with the VLA. From our original data, we have obtained data cubes with resolutions ranging from 13" to 45". The H I is observed to break up into small condensations at high resolution. These condensations, with typical masses of 3.3±0.7 × 107 Msun, are not

Aims:We study the two-dimensional distribution and kinematics of the stellar and gaseous components in the centre of the blue compact dwarf galaxy He 2-10. The aim is to compare the kinematics of gas and stars in order to determine whether they are consistent with one another, or if stars and gas can be decoupled due to gravitational perturbations

The STARE instrument was the first to detect the transits of an extrasolar planet in 1999. To date it has performed one of the longest running searches for transits, being in nearly continous operations since July 2001 at Teide Observatory, Tenerife. We describe the instrumental setup and the scheme that is used for data acquisition, handling and
