The COST Action CA-15117 (CANTATA) is a research program that considers, in a coordinated and multidisciplinary way, the possibility to go beyond General Relativity (GR) at ultraviolet (quantum gravity) and infrared (cosmology) scales, scenarios on which Einstein’s theory fails. This is done by combining complementary aspects of theoretical physics, cosmology and astrophysics.

The main goal of this initiative is to construct an effective theory of gravity capable of encompassing both the phenomenology related to the lack of a quantum field theory of gravity, and the phenomenology related to the various astrophysical scales (e.g self-gravitating systems, galaxies, large scale structure) that cannot be explained within the framework of GR without including dark matter and dark energy.

The CANTATA collaboration involves researchers from 26 different countries. An efficient way to find out who and where does what is by locating them on a map with basic information about the group name and a link to their website. If you are a member of CANTATA and want to advertise your group here, please send us an email at with the subject CANTATA map. Following the examples below, you should send us the following information:
  • Coordinates (or google maps link) of your institution.
  • Name of your institution and research group.
  • Link to your group website.

Video: Cantata In G Major

In a complex society like ours, effective scientific communication cannot limit itself to the mere transmission of information. New and more sofisticated strategies must be explored in order to reach the potentially interested target audience. It is with this phylosophy in mind that we have produced a short promotional video with fancy 3D animations and dynamical effects that illustrate who we are, what we do, and where we want to reach.
