Context. The mass-size relation is a fundamental galaxy scaling that intrinsically linked to formation and evolution. physical processes involved in growth leave their particular imprint on the between stellar or total mass size. Aims. We aim explore effect of large-scale environment using samples selection added-value products from Calar Alto Void Integral-field Treasury surveY (CAVITY) collaboration. Methods. analysed Petrosian R50 R90 radii SDSS DR16 images sample ≈14 000 galaxies...
Context. Void galaxies are essential for understanding the physical processes that drive galaxy evolution because they less affected by external factors than in denser environments, is, filaments, walls, and clusters. The stellar metallicity of a traces accumulated fossil record star formation through entire life galaxy. A comparison various including voids, clusters can provide valuable insights into how large-scale environment affects chemical Aims. We present first relation total mass...
The Universe is shaped as a web-like structure, formed by clusters, filaments, and walls that leave large volumes in between named voids. Galaxies voids have been found to be of later type, bluer, less massive, slower evolution than galaxies denser environments (filaments walls). However, the effect void environment on their stellar population properties still unclear. We aim address this question using 118 optical integral field unit datacubes from Calar Alto Void Integral-field Treasury...
We have learnt in the last decades that majority of galaxies belong to high density regions interconnected a sponge-like fashion. This large-scale structure is characterised by clusters, filaments, and walls, where most concentrate, but also under-dense called voids. The void within represent an ideal place for study galaxy formation evolution, as they are largely unaffected complex physical processes transform high-density environments. may hold key answer current challenges Lambda CDM...

Context. The present study addresses a key question related to our understanding of the relation between void galaxies and their environment: relationship luminous dark matter in around voids. Aims. To explore extent which local Universe voids are empty matter, we full (dark+luminous) content seven nearby cosmic that fully contained within CosmicFlows-3 volume. Methods. We obtained matter-density profiles using two independent methods. These were built from galaxy redshift space two-point...
Cosmic voids, distinguished by their low-density environment, provide a unique opportunity to explore the interplay between cosmic environment and processes of galaxy formation evolution. Nevertheless, few data on molecular gas have been obtained so far. In this paper, we continue research performed in CO-CAVITY pilot project study content properties void galaxies order search for possible differences compared that inhabit denser structures. We used IRAM 30\,m telescope observe CO(1--0)...
The Universe is shaped as a web-like structure, formed by clusters, filaments, and walls that leave large low number-density volumes in between named voids. Galaxies voids have been found to be of later type, bluer, less massive, slower evolution than galaxies denser environments (filaments walls).

The Calar Alto Void Integral-field Treasury surveY (CAVITY) is a legacy project aimed at characterising the population of galaxies inhabiting voids, which are most under-dense regions cosmic web, located in Local Universe. This paper describes first public data release (DR1) CAVITY, comprising science-grade optical cubes for initial 100 out total ~300 Universe (0.005 < z 0.050). These were acquired using integral-field spectrograph PMAS/PPak mounted on 3.5m telescope observatory. DR1...
