Secular- and merger-built bulges in barred galaxies
Context. Historically, galaxy bulges were thought to be single-component objects at the center of galaxies. However, this picture is now questioned since...
Seeking footprints of the primeval Universe in dwarf galaxies
We present the star formation histories (SFHs) of four isolated dwarf galaxies, Cetus, Tucana, LGS-3, and Phoenix, as a function of galactocentric radius. Our...
Self-interacting dark matter and the delay of supermassive black hole growth
Using cosmological hydrodynamic simulations with physically motivated models of supermassive black hole (SMBH) formation and growth, we compare the assembly of...
Self-interacting dark matter and the delay of supermassive black hole growth
Using cosmological hydrodynamic simulations with physically motivated models of supermassive black hole (SMBH) formation and growth, we compare the assembly of...
Separation between RR Lyrae and type II Cepheids and their importance for a distance determination: the case of omega Cen
The separation between RR Lyrae (RRLs) and type II Cepheid (T2Cs) variables based on their period is debated. Both types of variable stars are distance...
Serendipitous detection of an overdensity of Herschel-SPIRE 250 μm sources south of MRC 1138-26
We report the serendipitous detection of a significant overdensity of Herschel-Spectral and Photometric Imaging Receiver 250 μm sources in the vicinity of MRC...
Serendipitous discovery of a strong-lensed galaxy in integral field spectroscopy from MUSE
2MASX J04035024-0239275 is a bright red elliptical galaxy at redshift 0.0661 that presents two extended sources at 2″ to the north-east and 1″ to the south-west...
Seven young star clusters in the inner region of the Small Magellanic Cloud
We present CCD photometry in the Washington system C and T1 passbands down to T1 ~ 22 in the fields of L35, L45, L49, L50, L62, L63 and L85, seven poorly...
Shakhbazian compact galaxy groups. III. Photometric and spectroscopic study of ShCG 181, ShCG 344,ShCG 361, and ShCG 362
In 1995 we commenced a detailed spectral and photometric study of Shakhbazian compact groups. In this paper the results on groups ShCG 181, ShCG 344, ShCG 361...
