Line-of-sight velocity fields in an irregular sunspot (NOAA 8990) have been determined from Stokes-I spectra of the line Fe I 630.15 nm, obtained with the La Palma Stokes Polarimeter at the Swedish Vacuum Solar Telescope on May 13, 2000. We show and discuss the resulting velocity maps and asymmetry of the Fe I line.

The coronal line region in AGN is an intermediate zone between the broad- and the narrow-line regions where lines with ionization potentials, IP >50 eV, are produced. Because these IP are not easily reachable in stars, coronal lines become unique tracers of the AGN activity. The coronal line region has so far remained unresolved as its typical size

We present VLT-FORS1 color-magnitude diagrams (CMDs) reaching the oldest main-sequence turnoffs for three fields at two galactocentric distances in the Fornax dSph galaxy. We derive the star formation history (SFH) for each field through comparison with synthetic CMDs and show that the main epoch of star formation has extended to more recent epochs

Early-type (E/SO) galaxies follow tight relations such as the Fundamental Plane, the Color-Magnitude Relation or the Mg2-σ relation (Bender et al. 1992). However little is known about the relation between their morphological shapes and stellar populations (Conselice 2003), most likely because these two fields rely on methods that have grown up

At less than 4 Mpc away, Centaurus A (NGC 5128) is the nearest massive elliptical galaxy, the nearest radio galaxy, and the nearest recent merger. It is the ideal laboratory to study the connection between merging, massive black holes, the source of radio jets and merger-induced star formation in detail. Using NAOS-CONICA, guiding on the dust
