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...
We report here first results concerning stellar oxygen abundances in M33. Non-LTE model atmosphere and non-LTE line formation calculations were used to...
The stellar populations of quiescent ultra-diffuse galaxies from optical to mid-infrared spectral energy distribution fitting
We use spectral energy distribution (SED) fitting to place constraints on the stellar population properties of 29 quiescent ultra-diffuse galaxies (UDGs) across...
The stellar spectral features of nearby galaxies in the near infrared: tracers of thermally pulsing asymptotic giant branch stars?
We analyse the stellar absorption features in high signal-to-noise ratio (S/N) near-infrared (NIR) spectra of the nuclear region of 12 nearby galaxies, mostly...
The Strong Gravitationally Lensed Herschel Galaxy HLock01: Optical Spectroscopy Reveals a Close Galaxy Merger with Evidence of Inflowing Gas
The submillimeter galaxy (SMG) HERMES J105751.1+573027 (hereafter HLock01) at z = 2.9574 ± 0.0001 is one of the brightest gravitationally lensed sources...
