Constraints on the dust extinction law of the Galaxy
This work explores data from a few surveys, most notably the serendipitous catalogue from the NASA SWIFT mission that made use of the NUV/optical camera UVOT...
Constraints on the formation of the globular cluster IC 4499 from multiwavelength photometry
We present new multiband photometry for the Galactic globular cluster IC 4499 extending well past the main-sequence turn-off in the U, B, V, R, I and DDO 51...
Convective core sizes in rotating massive stars. I. Constraints from solar metallicity OB field stars
Context. Spectroscopic studies of Galactic O and B stars show that many stars with masses above 8 M ⊙ have been observed in the Hertzsprung-Russell (HR) diagram...
Cool stars in the Galactic center as seen by APOGEE. M giants, AGB stars, and supergiant stars and candidates
The Galactic center region, including the nuclear disk, has until recently been largely avoided in chemical census studies because of extreme extinction and...
Crucial aspects of the initial mass function. I. The statistical correlation between the total mass of an ensemble of stars and its most massive star
Context. Our understanding of stellar systems depends on the adopted interpretation of the initial mass function, IMF φ(m). Unfortunately, there is not a common...
Crucial aspects of the initial mass function. II. The inference of total quantities from partial information on a cluster
Context. In a probabilistic framework of the interpretation of the initial mass function (IMF), the IMF cannot be arbitrarily normalized to the total mass, ℳ...
Dark halo structure in the Carina dwarf spheroidal galaxy: joint analysis of multiple stellar components
Photometric and spectroscopic observations of the Carina dSph revealed that this galaxy contains two dominant stellar populations of different age and...
Dark matter annihilation and the Galactic Centre Excess
We compare the surface brightness profile and morphology of the Galactic Centre Excess (GCE) identified in wide-angle γ-ray maps from the Fermi-Large Area...
Deep blank-field catalogue for medium- and large-sized telescopes
The observation of blank fields, defined as regions of the sky that are devoid of stars down to a given threshold magnitude, constitutes one of the most...
