Previous studies have discarded that flares in galactic discs may explain the truncation that are frequently observed in highly-inclined galaxies (Kregel et al...

PublicaciónTruncated Star Formation in Compact Groups of Galaxies: A Stellar Population Study
We present the results of a study comparing the stellar populations in the elliptical galaxies of Hickson compact groups (HCGs) with those in low-density...

PublicaciónTruncated stellar discs in the near infrared. II. Statistical properties and interpretation
The results obtained in Paper I are used to study possible relationships between the truncation radius of stellar discs in the NIR and structural parameters of...

PublicaciónTruncated stellar disks in the near infrared. I. Observations
We present NIR surface photometry of 11 edge-on galaxies obtained in the course of a long term project aimed at analysing the occurrence and type of the...

PublicaciónTwo Distinct Ancient Components in the Sculptor Dwarf Spheroidal Galaxy: First Results from the Dwarf Abundances and Radial Velocities Team
We have found evidence for the presence of two distinct ancient stellar components (both >=10 Gyr old) in the Sculptor dwarf spheroidal galaxy. We used the ESO...

PublicaciónTwo emission line objects with z > 0.2 in the optical filament apparently connecting the Seyfert galaxy NGC 7603 to its companion
We present new spectroscopic observations of an old case of anomalous redshift - NGC 7603 and its companion. The redshifts of the two galaxies which are...

PublicaciónTwo new confirmed massive relic galaxies: red nuggets in the present-day Universe
We confirm two new local massive relic galaxies, i.e. untouched survivors of the early Universe massive population: Mrk 1216 and PGC 032873. Both show early and...

PublicaciónTwo newly identified, relatively old star clusters in the Small Magellanic Cloud
We present the results on the age and metallicity estimates of the Small Magellanic Cloud (SMC) clusters L110, L112 and L113 obtained from CCD Washington CT1...

PublicaciónTwo physical regimes for the giant H II regions and giant molecular clouds in the Antennae galaxies
We have combined observations of the Antennae galaxies from the radio interferometer ALMA (Atacama Large Millimeter/submillimeter Array) and from the optical...
