The detection of gravitational waves (GWs) originating from a black hole (BH) binary merger in 2015 by LIGO marked the beginning of the age of GW astronomy. Another defining moment came in 2017 with the joint detection of GWs and their electromagnetic (EM) counterpart, beginning…

Gravitational waves were first predicted by Albert Einstein in 1916, a year after the development of his new theory of gravitation known as the general theory of relativity. This theory established gravitation as the curvature of space-time produced by matter and energy. To be d…

The existence of cosmic strings was proposed in the mid-seventies as a by-product of the various phase transitions that occured in the early Universe. Cosmic strings are one-dimensional topological defects; structures of extremely high energy density with infinitesimal widths an…
With the recent discovery of gravitational waves and high-energy cosmic neutrinos, we are witnessing the beginning of a new era in multimessenger astronomy. The exploration of the Universe through these new messengers, along with electromagnetic radiation and cosmic rays, gives …
While Big Bang cosmology successfully explains much of the history of our Universe, there are certain features it does not explain, for example the spatial flatness and uniformity of our Universe. One widely studied explanation for these features is cosmological inflation. The o…
