Galaxies in Cosmic Voids: CAVITY

Voids form a prominent aspect of the Megaparsec distribution of galaxies and matter. They are enormous regions with sizes in the range of 20 to 50 Mpc that are practically devoid of any galaxy, usually roundish in shape and occupying the major share of space in the Universe. Forming an essential and prominent aspect of the Cosmic Web, they are instrumental in the spatial organization of the Cosmic Web. Surrounded by elongated filaments, sheetlike walls and dense compact clusters, they weave the salient weblike pattern of galaxies and matter pervading the observable Universe. The shape and evolution of voids are highly sensitive to the nature of dark energy, while their substructure and galaxy population provides a direct key to the nature of dark matter. Moreover, the pristine environment of void interiors is an important testing ground for our understanding of
environmental influences on galaxy formation and evolution.

The CAVITY project is addressing the nature of galaxies in these cosmic voids. This conference will bring together the international team that forms CAVITY and all the work and science results obtained during the first successful year of the CAVITY project.

The meeting venue is located at the heart of the centric Realejo suburb where plenty of accommodation can be found.

The University owns in the area a really quaint residence for visitor: La corrala de Santiago. The Corrala has to be booked through us, and usually has limited space, so in case any of you is interested in staying at the Uni residence, please let us know well in advance so we can book it on your behalf.

If you need any extra help with the accommodation let us know.
