Galaxies and evolution of the Universe

  • Galaxy Formation and Evolution
    • The very high redshift Universe

Detection and characterization of Active Galaxies in the Primordial Universe, through the use of the most advanced observatories (HST, VLT, GMRT, ALMA) and/or by conducting very wide surveys (e.g. CFHT, VISTA, UKIRT). Here, we aim to map the evolution of star-forming galaxies and the AGN phenomenon throughout the Universe History.

    • Star-forming galaxies over the last 13 Billion years

We are conducting and exploring by far the largest Ha and Lya surveys (using custom made narrow-band filters) ever conducted all the way from z~0 to the highest redshifts, in order to unveil how galaxies like our own Milky Way formed and evolved. This includes investigating the roles of mass and environment in galaxy formation and evolution, and conducting a variety of follow-up observations with state-of-the-art instruments and telescopes (e.g. ALMA, KMOS, SINFONI, Suprime-cam/Subaru).

    • The Bulgeless Galaxy population out to z~1

We aim to characterize these "problematic" galaxy population, quantifying its AGN and Star Formation activity, in order to constrain current state-of-the-art models of galaxy formation and evolution.
    • The next-generation of radio telescopes

CAAUL participates in the definition and planning of the up-coming generation of radio-telescopes and their astronomical surveys:
        1. Atacama Large Millimetre Array
        2. Australia Square Kilometre Array Pathfinder - Evolutionary Map of the Universe survey
        3. Westerbork Radio Telescope and the new APERTIF detector - Westerbork Observations of the Deep Apertif Northern-sky survey
        4. MeerKAT - MeerKAT International GigaHertz Tiered Extragalactic Exploration survey
  • Weak gravitational lensing and large-scale structure of the Universe

  • Cosmological models: isotropic and anisotropicspatially homogeneous solutions to the Einstein Equations

  • Exact Solutions to the Einstein Field Equations: Black Holes, Lorentzian Wormholes and the Causal Structure of Spacetime
We aim to investigate issues on Black Hole physics, such as gravitational collapse; and on traversable wormholes, namely, minimizing the usage of exotic matter in modified theories of gravity and the respective stability issues.
    • Modified theories of gravity, Dark energy models, Averaged cosmologies
A central theme in Cosmology is the perplexing fact that the Universe is undergoing an accelerating expansion. The cause of this acceleration still remains an open and tantalizing question, and represents an imbalance in the governing gravitational equations. Our research aims to address the issue of the accelerated expansion of the Universe, whose resolution is so important for theoretical cosmology, looking beyond the standard theory of gravity.
