Division Web Page


Division J covers all thematics dealing with the physics of the Universe, and the physics of galaxies composing it, but not in particular the Milky Way, which is relevant to Div.H ("Interstellar Matter and Local Universe"). Also, some of the topics will be shared with Div.D ("High Energy Phenomena and Fundamental Physics").

The main topics can be listed in four categories:

  1. Physics and content of the Universe
    The early Universe, cosmological models;
    Baryonic and non-baryonic matter, dark matter and dark energy.
  2. Evolution of structures
    Cosmic backgrounds (CMB, and all backgrounds from radio to gamma-rays);
    Populations of galaxies, galaxy clusters and groups, intergalactic medium.
  3. Formation and evolution of galaxies
    Reionization, first objects (AGN, Starbursts), history of star formation;
    Physics of galaxies at all redshifts, role of the environment.
  4. Spatially resolved galaxies
    Star formation laws in galaxies, resolved stellar population;
    Dynamics of sub-structures (bulges, disks, spiral structure...).
