Executive Summary : | Dark Matter (DM) is a mysterious and active field of research, with almost 26 of our universe consisting of it. The Weakly Interacting Massive Particle (WIMP) was once considered the best candidate, but its undetectability has led to a new candidate, the Primordial Black Hole (PBH). The new late-formation mechanism involves an interacting fluid consisting of scalar field and beyond-standard model fermions. The researchers plan to use the modified Boltzmann Code CLASS to analyze the effect of late-forming PBHs on the cosmic microwave background and the latest epoch of PBH formation.
The detection of gravitational waves (GW) by LIGO has led to the discovery of primordial black holes (PBHs), which could be a potential candidate for dark matter (DM). The project aims to investigate the production of GWs and the stochastic gravitational wave background (SGWB) in the PBH formation mechanism scenario, allowing for a more sensitive detector. The study also aims to compare the GW and SGWB production between PBH merging and second-order perturbation, using Luca Amendola's experience with second-order perturbation theory and gravitational waves. |
