The gravitational wave landscape of cosmic string networks with varying tension
Luca Brunelli, Filippo Revello, Gonzalo Villa
We fully classify the phenomenology of gravitational wave emission from scaling cosmic string networks with varying tension and compute the spectral indices of the resulting stocha…
Cosmic superstrings in large volume compactifications: PTAs, LISA and time-varying tension
Anish Ghoshal, Filippo Revello, Gonzalo Villa
The Stochastic Gravitational Wave Background (SGWB) from cosmic superstrings offers one of the few known possibilities to test String Theory within current experimental reach. Howe…
Cosmic (super)strings with a time-varying tension
Filippo Revello, Gonzalo Villa
Cosmic (super)strings offer promising ways to test ideas about the early universe and physics at high energies. While in field theory constructions their tension is usually assumed…
Remarks on brane-antibrane inflation
Gonzalo Villa
We provide an accessible review to the eta problem in brane-antibrane inflation and a recently proposed solution. The description of the antibrane by means of nonlinearly realized…
