The Zero-Age Massive Stellar Population of W49A from VLA Observations
M. Juárez-Gama, R. Galván-Madrid, G. Suárez +14
We use all-configuration VLA data at 3.3 cm with a physical resolution of ~2000 AU to infer the embedded zero-age massive stellar population of the W49A protocluster, as traced by…
Reinterpreting the puzzling properties of z>6 galaxies within a variable IMF framework
Fabio Fontanot, Gabriella De Lucia, Lizhi Xie +6
Recent results form the James Webb Space Telescope (JWST) report space densities for bright and massive galaxies at z>7 that far exceed expectations of theoretical models of galaxy…
J-PLUS Reconstructing the Milky Way Disc's star formation history with twelve-filter photometry
J. A. Alzate-Trujillo, A. del Pino, C. López-Sanjuan +23
Wide-field, multi-filter photometric surveys enable the reconstruction of the Milky Way's star formation history (SFH) on Galactic scales and offer new insights into disc assembly.…
Synthetic JWST galaxy images in the TNG50 simulation - I. Model validation and comparison to observations
Alejandro Guzmán-Ortega, Gustavo Bruzual, Vicente Rodriguez-Gomez +1
We use the TNG50 cosmological simulation and three-dimensional radiative transfer post-processing to generate dust-aware synthetic observations of galaxies at a…
Semi-empirical versus Theoretical Stellar Population Models: a comparison with Star Clusters
Randa Asad, Paula R. T. Coelho, Johina M. John +3
Stellar population synthesis (SPS) models are a key tool for deriving the age, metallicity, radial velocity and reddening of star clusters from their integrated spectra. Using a sa…
The Youngest Star Clusters in the Large Magellanic Cloud
Ricardo Chávez, Rosa Amelia González-Lópezlira, Gustavo Bruzual
This study presents a comprehensive analysis of the youngest stellar clusters in the Large Magellanic Cloud (LMC), utilising a multi-wavelength approach. We analyse data spanning f…
