Using the Illustris cosmological simulation, we investigate the origin of fossil groups in the {M}200={10}13{--}{10}13.5 {M}⊙ {h}-1 mass regime. We examine the...
Are luminous radio-loud active galactic nuclei triggered by galaxy interactions?
We present the results of a comparison between the optical morphologies of a complete sample of 46 southern 2 Jy radio galaxies at intermediate redshifts (0.05...
Are radio-loud Broad Absorption Line Quasars young sources?
Studying Broad Absorption Line Quasars (BAL QSOs) is interesting because they probe the physics of the AGN environment, and because AGN outflows are important...
Are the stellar winds in IC 1613 stronger than expected?
In this poster we present the results of our analyses of three early massive stars in IC 1613, whose spectra have been observed with VIMOS and analyzed with...
Now almost 70 years since its introduction, the effective or half-light radius has become a very popular choice for characterising galaxy size. However, the...
Aims: The knowledge of physical conditions in young radio sources is important for defining the framework of models describing radio source evolution. We...
Arm and interarm abundance gradients in CALIFA spiral galaxies
Spiral arms are the most singular features in disc galaxies. These structures can exhibit different patterns, namely grand design and flocculent arms, with...
Arm-interarm gas abundance variations explored with MUSE: the role of spiral structure in the chemical enrichment of galaxies
Spiral arms are the most characteristic features of disc galaxies, easily distinguishable due to their association with ongoing star formation. However, the...
Around-the-Clock Observations of the Q0957+561A,B Gravitationally Lensed Quasar. II. Results for the Second Observing Season
We report on an observing campaign in 2001 March to monitor the brightness of the later arriving Q0957+561B image in order to compare with the previously...
