Context: The determination of the lower-end of the initial mass function (IMF) provides strong constraints on star formation theories. Aims: We report here on a...
Young [α/Fe]-enhanced stars discovered by CoRoT and APOGEE: What is their origin?
We report the discovery of a group of apparently young CoRoT red-giant stars exhibiting enhanced [α/Fe] abundance ratios (as determined from APOGEE spectra)...
Young, metal-enriched cores in early-type dwarf galaxies in the Virgo cluster based on colour gradients
Early-type dwarf galaxies are not simply featureless, old objects, but were found to be much more diverse, hosting substructures and a variety of stellar...
z-GAL: A NOEMA spectroscopic redshift survey of bright Herschel galaxies. I. Overview
Using the IRAM NOrthern Extended Millimetre Array (NOEMA), we conducted a Large Programme (z-GAL) to measure redshifts for 126 bright galaxies detected in the...
z-GAL: A NOEMA spectroscopic redshift survey of bright Herschel galaxies. II. Dust properties
We present the dust properties of 125 bright Herschel galaxies selected from the z-GAL NOEMA spectroscopic redshift survey. All the galaxies have precise...
z-GAL: A NOEMA spectroscopic redshift survey of bright Herschel galaxies. III. Physical properties
The z-GAL survey observed 137 bright Herschel-selected targets with the IRAM Northern Extended Millimeter Array, with the aim to measure their redshift and...
Zeeman effect in sulfur monoxide. A tool to probe magnetic fields in star forming regions
Context. Magnetic fields play a fundamental role in star formation processes and the best method to evaluate their intensity is to measure the Zeeman effect of...
The formation time scales of quiescent galaxies can be estimated in two different ways: by their star formation history and by their chemistry. Previously, the...
