Emission of gravitational waves by superconducting cosmic strings

I. Yu. Rybak, L. Sousa

We study the gravitational radiation emission efficiency of superconducting cosmic strings. We demonstrate, by using a solvable model of transonic strings, that the presence of…

Primordial magnetic fields in theories of gravity with non-minimal coupling between curvature and matter

Orfeu Bertolami, Maria Margarida Lima, Filipe C. Mena

The existence of magnetic fields in the universe is unmistakable. They are observed at all scales from stars to galaxy clusters. However, the origin of these fields remains enigmat…

Multi-field cold and warm inflation and the de Sitter swampland conjectures

Orfeu Bertolami, Paulo M. Sá

We discuss under which conditions multi-field cold and warm inflationary models with canonical kinetic energy terms are compatible with the swampland conjectures about the emergenc…

Observational signatures of hot spots orbiting horizonless objects

João Luís Rosa, Paulo Garcia, Frédéric H. Vincent +1

Pushed by a number of advances, electromagnetic observatories have now reached the horizon scale of supermassive black holes. The existence and properties of horizons in our univer…

Quantum kinetic theory of Jeans instability in non-minimal matter-curvature coupling gravity

Cláudio Gomes, Kamel Ourabah

We present a quantum treatment of the Jeans gravitational instability in the Newtonian limit of the non-minimal matter-curvature coupling gravity model. By relying on Wigner functi…

On-shell Lagrangian of an ideal gas

P. P. Avelino, R. P. L. Azevedo

In the context of general relativity, both energy and linear momentum constraints lead to the same equation for the evolution of the speed of free localized particles with fixed pr…
