cds-question@unistra.frgalaxiesgalaxy-classification-systemsredshiftedspectroscopyThe mass in the Universe is distributed non-uniformly, originating the Large Scale Structure (LSS), characterised by clusters, filaments, walls and voids. Galaxies in voids have been found to be bluer, of later type, less massive, and to have slower evolution than galaxies in denser large-scale environments. The effect of the void environment on many other evolutionary properties, such as the star formation rate (SFR), is still a topic under discussion. We tackle this problem with a new perspective by estimating the spatially-resolved SFR derived from extinction-corrected H{alpha} luminosities of a sample of 220 void galaxies from the Calar Alto Void Integral-field Treasury surveY (CAVITY) project. These observations consist of optical integral field unit datacubes obtained with the PMAS/PPaK spectrograph at the 3.5m telescope at the Calar Alto Observatory (Almeria, Spain). We measure their continuum-subtracted emission lines to obtain the maps of the SFR, specific star formation rate (sSFR) and extinction (A_V). From them, we assess the behaviour of the whole galaxies through their global properties, and the spatially-resolved information with radial profiles up to 2 half-light radii. We then compare the results with a sample of galaxies in filaments and walls from the CALIFA survey analysed using the same methodology. We build a control sample matched in morphological type and total stellar mass by taking pairs of each CAVITY galaxy. We find no statistically significant differences in the SFR and sSFR (p<=0.05), although void galaxies tend to have larger SFR, especially for the early spirals.This effect is present for Sa galaxies at all galactocentric distances ({DELTA}logsSFR[Gyr^-1^]=0.25dex at 1 half light radius, HLR), and can also be seen in the outer parts (R>1HLR) of late-type spirals ({DELTA}logsSFR[Gyr^-1^]=0.26dex at 2 HLR), evidencing a slower transition from star-forming to quiescent and less evolved spiral discs. Additionally, we find void late-type galaxies to have lower extinction ({DELTA}=0.16+/-0.06mag). Using the extinction normalised by the stellar mass surface density as a proxy for the gas mass fraction, we find it to be larger for the void early spirals (by a 5%), especially in their outer regions (23% larger). This indicates the effect of the void environment on the transition stage from star forming to passive.2026A&A...709A.227Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/709/A227CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/691/A161 : CAVITY.
