I review here the spatially-resolved spectroscopic properties of low-redshift star-forming galaxies (and their retired counter-parts), using results from the most recent Integral Field Spectroscopy galaxy surveys. First, I briefly summarise the global spectroscopic properties of these galaxies, discussing the main ionization processes, and the global relations described between the star-formation rates, oxygen abundances, and average properties of their stellar populations (age and metallicity) with the stellar mass. Second, I present the local distribution of the ionizing processes, down to kiloparsec scales, and I show how the global scaling relations found between integrated parameters (like the star-formation main sequence, mass-metallicity relation and Schmidt-Kennicutt law) present local/resolved counter-parts, with the global ones being just integrated/average versions of the local ones. I discuss the local/resolved star-formation and chemical enrichment histories and their implication on the inside-out growth of galaxies. Third, I present the radial distributions of the surface densities of the properties explored globally, and how they depend on the integrated galaxy properties. Finally, I summarise all these results and discuss what we have learned from them regarding the evolution of galaxies.

  1. ALMA CO-CAVITY II. Resolved Scaling Relations in Void Galaxies

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    In void galaxies, the resolved relation between molecular gas and stellar mass is the tightest of the three star-formation scaling relations, with 0.16 dex scatter.

  2. The EDGE-CALIFA survey: Star formation relationships for galaxies at different stages of their evolution

    astro-ph.GA 2025-07 conditional novelty 6.0 of 10

    Across quenching stages in 643 CALIFA galaxies, molecular gas decreases, but the decisive step beyond the green valley is a drop in star formation efficiency, especially in the inner regions.

  3. Ageing and Quenching: Influence of Galaxy Environment and Nuclear Activity in Transition Stage

    astro-ph.GA 2024-11 reject novelty 4.0 of 10

    In SDSS galaxies at the transition stage, slow ageing is environment-dependent and sensitive to nuclear activity, while fast quenching shows no significant environmental dependence.
