We present the most comprehensive set of empirical optical strong-line metallicity calibrations to date, based on the DEep Spectra of Ionised REgions Database (DESIRED), the larges…
The CAVITY project. The spatially resolved SFR of galaxies in voids
Ana M. Conrado, Rubén García-Benito, Rosa M. González Delgado +24
The mass in the Universe is distributed non-uniformly, originating the Large Scale Structure (LSS), characterised by clusters, filaments, walls and voids. Galaxies in voids are blu…
