The necessity of dark matter in MOND within galactic scales
Ignacio Ferreras, Mairi Sakellariadou, Muhammad Furqaan Yusaf
To further test MOdified Newtonian Dynamics (MOND) on galactic scales -- originally proposed to explain the rotation curves of disk galaxies without dark matter -- we study a sampl…
Non-vacuum initial states for the cosmological perturbations and the back-reaction problem of inflation
Alejandro Gangui, Jerome Martin, Mairi Sakellariadou
In the framework of Inflationary theory, the assumption that the quantum state of the perturbations is a non-vacuum state leads to a difficulty: non-vacuum initial states imply, in…
CMB: The ultimate test for theoretical models aiming at describing the very early universe
Mairi Sakellariadou
In this talk, I will illustrate how one can use the cosmic microwave background anisotropy measurements, in order to test theoretical models aiming at describing the early universe…
Cosmic Microwave Background Anisotropies: Inflation versus Topological Defects
Mairi Sakellariadou
I present a briefly summary of the current status of inflationary models versus topological defects scenarios, as the mechanisms which could have induced the initial density pertur…
The Nexus between Cosmology and Elementary Particle Physics: Testing Theoretical Speculations through Observations of the Cosmic Microwave Background Anisotropies
Mairi Sakellariadou
The origin of the large scale structure in the universe - galaxies, quasars, clusters, voids, sheets - is one of the most important questions in cosmology. One can show that some n…
Cosmic Strings and Coherence
Mark Hindmarsh, Mairi Sakellariadou, Graham R. Vincent
Cosmic strings provide a radically different paradigm for the formation of structure to the prevailing inflationary one. They afford some extra technical complications: for example…
