DOI: 10.1002/asna.20240018
Abstract: We exploit the astro‐photometric dataset of the multi‐epoch infrared parallel field of a Hubble Space Telescope Large Programme aimed at studying the faintest stars of the globular cluster NGC 6752 to determine the luminosity and… read more here.

DOI: 10.1051/0004-6361/202040017
Abstract: Aims. Based on a local sample from Gaia DR2 catalogue composed of 74 339 stars, we are able to derive more accurate kinematic statistics defining the local stellar populations and classify the stars in terms… read more here.

SDSS-IV MaNGA: Excavating the fossil record of stellar populations in spiral galaxies
Sign Up to like & getrecommendations! Published in 2020 at "Monthly Notices of the Royal Astronomical Society"
DOI: 10.1093/mnras/staa1303
Abstract: We perform a “fossil record” analysis for ≈800 low-redshift spiral galaxies, using STARLIGHT applied to integral field spectroscopic observations from the SDSS-IV MaNGA survey to obtain fully spatially-resolved high-resolution star formation histories (SFHs). From the… read more here.

DOI: 10.1093/mnras/staa2089
Abstract: The binary fraction of a stellar population can have pronounced effects on its properties, and in particular the number counts of different massive star types, and the relative subtype rates of the supernovae which end… read more here.

DOI: 10.1093/mnras/stab1987
Abstract: Integral field unit spectra of face-on star-forming galaxies from the MaNGA survey are stacked in radial bins so as to reach an S/N high enough to measure emission lines and Lick indices out to 2.5–3Re.… read more here.

DOI: 10.1093/mnras/stab2412
Abstract: We measured the equivalent width of a large set of near-infrared (NIR, 0.8–2.4$\ \mu$m) line-strength indices in XShooter medium-resolution spectra of the central regions of 14 galaxies. We found that two aluminum indices, Al at… read more here.

DOI: 10.1093/mnras/stae448
Abstract: Stellar population studies of massive early-type galaxies (ETGs) suggest that the stellar initial mass function may not be universal. In particular, the centres of ETGs seem to contain an excess of low-mass dwarf stars compared… read more here.

DOI: 10.1093/mnras/staf001
Abstract: While JWST has observed galaxies assembling as early as z ∼ 14, evidence of galaxies with significant old stellar populations in the Epoch of Reionisation (EoR) – the descendants of these earliest galaxies – are… read more here.

DOI: 10.1093/mnras/staf1070
Abstract: The combination of the high-resolution ALMA, JWST and HST observations provides unprecedented insights into the connection between individual molecular clouds and their internal stellar populations in nearby galaxies. The molecular clouds in five nearby galaxies… read more here.
