The Standard Model is widely accepted as one of the most successful predictive theories of Physics, providing insight into the fundamental building blocks of the universe. Over the last few decades this model has shown signs of incompleteness, most of which are attributed to Neutrinos. Within the confines of the standard model a discrepancy exists related to vanishing Neutrino masses, which...

Gamma-Ray Bursts (GRBs) have been detected to very high redshift (z = 9.4) which make them interesting cosmological probes. In attempts to use GRBs as cosmological standard candles, like Type-Ia supernovae (SNe), many studies have been conducted throughout in recent decades. These studies explore different phenomenological relations, such as the Amati and Yonetoku correlations between the GRB...

The detection of Gravitational Waves (GWs) allows the study of massive binary systems that may or may not have any electromagnetic (EM) emission. The joint detection of GW~170817 and the Gamma Ray Burst (GRB) GRB~170817A, marked the beginning of GW multi-messenger astronomy. It presented the potential to reveal new insights into the emission mechanisms of GRBs as well as a more accurate...
