Optical microvariability (OM, small amplitude variations in time scales from minutes to hours) in radio-quiet quasars (RQQ) may be as frequent as in radio-loud...
Spectral study of the diffuse synchrotron source in the galaxy cluster Abell 523
The galaxy cluster Abell 523 (A523) hosts an extended diffuse synchrotron source historically classified as a radio halo. Its radio power at 1.4 GHz makes it...
Spectro-photometric close pairs in GOODS-S: major and minor companions of intermediate-mass galaxies
Aims: Recent work has shown that major mergers of disc galaxies can only account for 20% of the growth of the galaxy red sequence between z = 1 and z = 0. Our...
Spectro-photometric decomposition of galaxy structural components
Galaxies are complex systems made up of different structural components such as bulges, discs, and bars. Understanding galaxy evolution requires unveiling...
Spectro-photometric evolution of elliptical galaxies. II. Models with infall.
In this paper we present new chemo-spectro-photometric models of elliptical galaxies in which infall of primordial gas is allowed to occur. They aim to simulate...
Spectrophotometric Investigations of Blue Compact Dwarf Galaxies: Markarian 35
We present results from a detailed spectrophotometric analysis of the blue compact dwarf galaxy Mrk 35 (Haro 3), based on deep optical (BVRI) and near-IR (JHK)...
Spectrophotometric investigations of the blue compact dwarf galaxy Mrk 35
Preliminary results from a detailed spectrophotometric analysis of the blue compact dwarf galaxy (BCD) Mrk 35 are presented. We have performed deep UBVRI broad...
Spectrophotometric Observations of Blue Compact Dwarf Galaxies: Markarian 370
We present results from a detailed spectrophotometric analysis of the blue compact dwarf galaxy (BCD) Mrk 370, based on deep UBVRI broadband and Hα narrowband...
