We report on the detection of a stellar halo around NGC 1560, a 109 M ⊙ spiral galaxy member of the Maffei group. We obtained deep images in the r- and i-bands...
The stellar host in blue compact dwarf galaxies. The need for a two-dimensional fit
Context: The structural properties of the low surface brightness stellar host in blue compact dwarf galaxies are often studied by fitting r1/n models to the...
The stellar host in star-forming low-mass galaxies: Evidence for two classes
Context. The morphological evolution of star-forming galaxies provides important clues to understand their physical properties, as well as the triggering and...
The Stellar Initial Mass Function at 0.9 < z < 1.5
We explore the stellar initial mass function (IMF) of a sample of 49 massive quiescent galaxies (MQGs) at 0.9 z 1.5. We base our analysis on intermediate...
The Stellar Kinematic Center and the True Galactic Nucleus of NGC 253
We present the first sub-arcsecond resolution two-dimensional stellar kinematics and X-ray observations of the prototypical starburst galaxy NGC 253 which...
The stellar mass function of quiescent and star-forming galaxies and its dependence on morphology in COSMOS-Web
We study the stellar mass function (SMF) of quiescent and star-forming galaxies and its dependence on morphology in ten redshift bins at 0.2 < z < 5.5. We used...
The stellar occultation by (319) Leona on 2023 September 13 in preparation for the occultation of Betelgeuse
On 2023 December 12, the star α Orionis will be occulted by asteroid (319) Leona. This represents an extraordinary and unique opportunity to analyse the...
The stellar orbit distribution in present-day galaxies inferred from the CALIFA survey
Galaxy formation entails the hierarchical assembly of mass, along with the condensation of baryons and the ensuing, self-regulating star formation1,2. The stars...
We report here first results concerning stellar oxygen abundances in M33. Non-LTE model atmosphere and non-LTE line formation calculations were used to...
