Induced gravitational waves, metastable cosmic strings and primordial black holes in GUTs

Rinku Maji, Ahmad Moursy, Qaisar Shafi

We explore the cosmological and astrophysical implications of a realistic hybrid inflation model based on flipped . The model contains superheavy metastable cosmic strings a…

Primordial monopoles, black holes and gravitational waves

Ahmad Moursy, Qaisar Shafi

We show how topologically stable superheavy magnetic monopoles and primordial black holes can be generated at observable levels by the waterfall field in hybrid inflation models ba…
