Near-UV Merger Signatures in Early-Type Galaxies,ly-type galaxies without obvious dust or active galactic nuclei. Near-UV imaging is a sensitive probe for the detection of younger components with ages in the range of 10 Myr to 5 Gyr. Only two galaxies have central colors (r< 0.75 r.) that are consistent with a single-generation population. The other ten require a composite population.

The Impact of Encounters on the Members of Local Group Analogs. A View from , ,axy morphology. UV-bright regions, sites of intense star formation activity accompanied by intense dust extinction, mark the galaxy outskirts forming irregular structures and tails. Compared to the Local Group, LGG 225 seems thus to be experiencing a more intense and active evolutionary phase.

An Atlas of GALEX UV Spectra Selected from the CDFS,d 0.3. The extracted spectra were compared with theoretical templates obtained from the Starburst99 population synthesis code. Two curves of extinction were applied to them in order to estimate the extinction of the selected galaxies.

Colours of the Envelopes of cD Galaxies,ctive star formation. In two cDs with multiple nuclei (A193 and A2634), no colour gradients or regions of current active star formation were found. These results favour an early, ‘primordial origin’ for the cD envelope, the stellar populations of the envelope being coeval with those of the central elliptical galaxy.
