Context: The analysis of unresolved stellar populations demands evolutionary synthesis models with realistic physical ingredients and extended wavelength coverage. Aims: We quantitatively describe the first CO bandhead at 2.3 μm to allow stellar population models to provide improved predictions in this wavelength range. Methods: We observed a new

We measured the stellar kinematics of three face-on galaxies with the aim of searching for box/peanut-shaped (B/P) bulges. These observations test and confirm that face-on B/P bulges can be recognized by two minima in the radial profile of the fourth Gauss-Hermite moment h_4 of the line-of-sight velocity distribution measured along the bar major

Aims: To show the importance of high-spatial resolution observations of H II regions when compared with observations obtained with larger apertures such as ISO, we present mid-infrared spectra of two Magellanic Cloud H II regions, N88 A and N160 A. Methods: We obtained mid-infrared (8-13 μm), long-slit spectra with TIMMI2 on the ESO 3.6 m telescope
