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…
Simultaneous analysis of SDSS spectra and GALEX photometry with STARLIGHT: Method and early results
Ariel Werle, Roberto Cid Fernandes, Natalia Vale Asari +4
We combine data from the Sloan Digital Sky Survey and the Galaxy Evolution Explorer to simultaneously analyze optical spectra and ultraviolet photometry of 231643 galaxies with the…
A novel method to automatically detect and measure the ages of star clusters in nearby galaxies: Application to the Large Magellanic Cloud
T. Bitsakis, P. Bonfini, R. A. Gonzalez-Lopezlira +5
We present our new, fully-automated method to detect and measure the ages of star clusters in nearby galaxies, where individual stars can be resolved. The method relies purely on s…
Asymmetric mass models of disk galaxies - I. Messier 99
Laurent Chemin, Jean-Marc Hure, Caroline Soubiran +3
Mass models of galactic disks traditionally rely on axisymmetric density and rotation curves, paradoxically acting as if their most remarkable asymmetric features, such as lopsided…
Variations of the stellar initial mass function in the progenitors of massive early-type galaxies and in extreme starburst environments
G. Chabrier, P. Hennebelle, P. Charlot
We examine variations of the stellar initial mass function (IMF) in extreme environments within the formalism derived by Hennebelle \& Chabrier. We focus on conditions encountered…
Variations of the Initial Mass Function in Semi-Analytical models
Fabio Fontanot
Deviations from a universal, MW-like, Stellar Initial Mass Function (IMF) have been reported for distant galaxies, although the physical reason behind the observed variations is st…
