SKAO scientific potential will revolutionize multiple fields in Astrophysics. In this seminar after introducing the role of the observatory in future Astronomy we will present its scientific potential in Gravitational Waves science.

I review the status of the experimental signs of new Higgs bosons at the electroweak scale in particular the excesses at 95 GeV and 152 GeV.

We show that nonsingular black holes (BHs) realized in nonlinear electrodynamics are always prone to Laplacian instability around the center because of a negative squared sound speed in the angular direction.

The semi-classical contribution of black holes to the grand-canonical partition function of gravity is obtained by evaluating their Euclidean on-shell action.

Everything in our universe is made of matter and not antimatter and we do not understand why. An exciting possibility is that this asymmetry between baryons and antibaryons was created during the electroweak phase transition.

Cosmological observations like BBN and CMB offer crucial insights into the Early Universe enabling us to trace its evolution back to lifetimes as short as 0.01 seconds and testing different extensions of the Standard model if they decay at such times.

Despite the remarkable success of the Standard Model in describing nature experimental evidence suggests the existence of new physics beyond its framework.

In this talk I will show how an infinite tower of higher-curvature corrections to Einstein gravity gives rise to the formation of regular black holes in space-time dimensions larger than four.

Generalised symmetries have expanded our insight into theory but their impact has not fully translated into phenomenology yet.

Dark photons arising at or below the GeV scale from a spontaneously broken gauge symmetry are one of the simplest and most exciting extensions of the Standard Model.
