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...
Galaxy mergers are pivotal events in the evolutionary history of galaxies, with their impact believed to be particularly significant dwarf galaxies due low masses. However, these remain largely underexplored, especially pristine environments such as voids. In this work, we report serendipitous identification an isolated merging system a total stellar mass M_ ⋆ ∼ 10^9.7 ⊙, located centre cosmic void. This is one rare examples, and possibly first, galaxy pairs studied within central region...
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...
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)...

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, walls, where most concentrate, but also under-dense regions, called voids. The void and within represent an ideal place for study galaxy formation evolution as they are largely unaffected complex physical processes transform high-density environments. These can hold key well answer current...
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...
Context. The specific environment of galaxies may play a key role in their evolution. Large extragalactic surveys make it possible to study not only within local environment, but also the large-scale structure Universe. Aims. We aim investigate how influences star formation history (SFH) across range environments. Methods. categorised sample 9384 into three primary structures (voids, walls and filaments, clusters). further classified them based on (as either ‘singlets’ or group members)...
We aim to investigate how the local environment influences star formation history (SFH) of galaxies residing in various large-scale environments. categorise a sample 9384 into three primary large scale structures (voids, walls \& filaments, and clusters) further classify them based on their (as either "singlets" or group members), through search companion within sky-projected distances $\Delta r_p < 0.45$ Mpc velocity differences v 160$ $\text{km s}^{-1}$. Subsequently, we explore these...
We present the analysis using pyPipe3D of a sample 208 galaxies from CAVITY project , that includes: (i) description processes performed by this pipeline, (ii) data model adopted to store spatially resolved properties, and (iii) catalog comprising integrated characteristics slope radial gradients for various observational physical parameters determined each galaxy. elucidate outcomes presenting spatial distribution derived representative galaxy, CAVITY66239, exploring extensive intensive...
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. Data on molecular gas has been scarce so far. In this paper, we continue previous research done in CO-CAVITY pilot project study content properties void galaxies search for possible differences compared that inhabit denser structures. We observed at IRAM 30 m telescope CO(1-0) CO(2-1) emission 106 selected...
