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...

PublicationTwo 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...

PublicationTwo 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...

PublicationTwo 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...

PublicationTwo 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...

PublicationTwo Tails in NGC 3656 and the Major Merger Origin of Shell and Minor-Axis Dust Lane Elliptical Galaxies
I report on the discovery of two faint (~26.8 R mag arcsec-2) tidal tails around the shell elliptical galaxy NGC 3656 (Arp 155). This galaxy had previously been...

PublicationTwo-dimensional Kinematical and Ionization Structure of the Warm Gas in the Nuclear Regions of Arp 220
Integral field optical spectroscopy using the INTEGRAL system has been used to characterize the kinematic and ionization properties of the warm gas within 2 kpc...

PublicationTwo-dimensional line-strength maps in three well-studied early-type galaxies
Integral field spectroscopy has been obtained for the nuclear regions of three large, well-studied, early-type galaxies. From these spectra we have obtained...

PublicationTwo-dimensional metallicity distribution of the ionized gas in NGC 628 and NGC 6946
Aims: We present here two H II region catalogues with azimuthal resolution for the two grand design galaxies NGC 628 and NGC 6946. With the help of these...
