Galactic CO maps
Carbon monoxide (CO) is the best tracer of Galactic molecular hydrogen H_2_. Its lowest rotational emission lines are in the radio regime, and thanks to Galactic rotation,... -
Open cluster red clump stars Lithium abundances
It has recently been suggested that all giant stars with masses below 2M_{sun} suffer an episode of surface lithium enrichment between the tip of the red giant branch (RGB) and... -
Carbon and oxygen in microlensed bulge dwarfs
Next to H and He, carbon is, together with oxygen, the most abundant element in the Universe and widely used when modelling the formation and evolution of galaxies and their... -
Faraday cubes Fields A B and C
Faraday tomography of a field centred on the extragalactic point source 3C 196 with the LOw Frequency ARray (LOFAR) revealed an intertwined structure of diffuse polarised... -
Stellar parameters and Li abundances from GES iDR6
After more than 50 years, astronomical research still struggles to reconstruct the history of lithium enrichment in the Galaxy and to establish the relative importance of the... -
Abundance-age relations with open clusters
Precise chemical abundances coupled with reliable ages are key ingredients to understand the chemical history of our Galaxy. Open Clusters (OCs) are useful for this purpose... -
3794 open clusters parameters
The structure and evolution of the spiral arms of the Milky Way are basic but long-standing questions in astronomy. Especially the lifetime of spiral arms, it is still a puzzle... -
GLOSTAR Galactic plane survey. II. SNR.
The properties of the population of Galactic supernova remnants (SNRs) are essential to our understanding of the dynamics of the interstellar medium (ISM) in the Milky Way.... -
Li abundance and mixing in giant stars
We aim to constrain the mixing processes in low-mass stars by investigating the behaviour of the Li surface abundance after the main sequence. We take advantage of the data from... -
TO stars metallicity estimate
The goal of the Turn-Off Primordial Stars survey (TOPoS) project is to find and analyse turn-off (TO) stars of extremely low metallicity. To select the targets for spectroscopic... -
Gaia RVS benchmark stars. I.
The Radial Velocity Spectrometer (RVS) on board the Gaia satellite is not provided with a wavelength calibration lamp. It uses its observations of stars with known radial... -
Spiral arms Gaia EDR3
Using the astrometry and integrated photometry from the Gaia Early Data Release 3 (EDR3), we map the density variations in the distribution of young Upper Main Sequence (UMS)... -
Effects of IMG on Galactic chemical enrichment
We have been seeing mounting evidence that the stellar initial mass function (IMF) might extend far beyond the canonical Mi~100M_{sun} limit, but the impact of such a hypothesis... -
Milky Way nuclear disk KMOS survey
In the central few degrees of the bulge of the Milky Way there is a flattened structure of gas, dust, and stars, known as the central molecular zone, that is similar to nuclear... -
Orphan stream RR Lyrae and non-variables
We present a chemo-dynamical study of the Orphan stellar stream using a catalog of RR Lyrae pulsating variable stars for which photometric, astrometric, and spectroscopic data... -
Heavy-elements heritage of the falling sky
A fundamental element of galaxy formation is the accretion of mass through mergers of satellites or gas. Recent dynamical analyses based on Gaia data have revealed major... -
3D Kinematics and age of OCs
Open Clusters (OCs) can trace with a great accuracy the evolution of the Galactic disk. The aim of this work is to study the kinematical behavior of the OC population over time.... -
Distance of HiGAL sources
Distances are key to determine the physical properties of sources. In the Galaxy, large (>10000) homogeneous samples of sources for which distance are available, covering the... -
Improving the open cluster census. I.
The census of open clusters in the Milky Way is in a never-before seen state of flux. Recent works have reported hundreds of new open clusters thanks to the incredible... -
Age dissection of the Milky Way discs
Ensemble studies of red-giant stars with exquisite asteroseismic (Kepler), spectroscopic (APOGEE), and astrometric (Gaia) constraints offer a novel opportunity to recast and...
