The Quest for the Nature of the Dark Matter: The Need of a New Paradigm

Autor: Fabrizio Nesti, Paolo Salucci, Nicola Turini

Publikováno v: Astronomy; Volume 2; Issue 2; Pages: 90-104

The phenomenon of the Dark matter baffles the researchers: the underlying dark particle has escaped so far the detection and its astrophysical role appears complex and entangled with that of the standard luminous particles. We propose that, in order

Metastable cosmic strings

Autor: Buchmuller, Wilfried, Domcke, Valerie, Schmitz, Kai

Many symmetry breaking patterns in grand unified theories (GUTs) give rise to cosmic strings that eventually decay when pairs of GUT monopoles spontaneously nucleate along the string cores. These strings are known as metastable cosmic strings and hav

The future Euclid space satellite mission will offer an invaluable opportunity to constrain modifications to general relativity at cosmic scales. We focus on modified gravity models characterised, at linear scales, by a scale-independent growth of pe

Cosmic Superstrings Revisited in Light of NANOGrav 15-Year Data

Autor: Ellis, John, Lewicki, Marek, Lin, Chunshan, Vaskonen, Ville

We analyze cosmic superstring models in light of NANOGrav 15-year pulsar timing data. A good fit is found for a string tension $G \mu \sim 10^{-12} - 10^{-11}$ and a string intercommutation probability $p \sim 10^{-3} - 10^{-1}$. Extrapolation to hig

The gravitational eikonal: from particle, string and brane collisions to black-hole encounters

Autor: Di Vecchia, Paolo, Heissenberg, Carlo, Russo, Rodolfo, Veneziano, Gabriele

Motivated by conceptual problems in quantum theories of gravity, the gravitational eikonal approach, inspired by its electromagnetic predecessor, has been successfully applied to the transplanckian energy collisions of elementary particles and string
