Insights into the highest natural scale: Finite naturalness challenges inflationary dynamics Open
We apply the criterion of finite naturalness to the limiting case of a generic heavy sector decoupled from the Standard Model. The sole and unavoidable exception to this decoupling arises from gravitational interactions. We demonstrate tha…

Systematic biases from ignoring environmental tidal effects in gravitational wave observations Open
Binary black hole systems are typically assumed to evolve in vacuum. However, the environment surrounding the binary components can influence their properties, such as their tidal deformability, affecting the gravitational waveform produce…

Is the formation of primordial black holes from single-field inflation compatible with standard cosmology? Open
In this work, we investigate the generation of primordial black holes (PBHs) within the framework of single-field inflationary models and their compatibility with the cosmological history of the Universe. Our results suggest that, dependin…

Tidal Love numbers and approximate universal relations for fermion soliton stars Open
Fermion soliton stars are a consistent model of exotic compact objects which involve a nonlinear interaction between a real scalar field and fermions through a Yukawa term. This interaction results in an effective fermion mass that depends…

Cosmological Consequences of Unconstrained Gravity and Electromagnetism Open
Motivated by the quantum description of gauge theories, we study the cosmological effects of relaxing the Hamiltonian and momentum constraints in general relativity and Gauss' law in electromagnetism. We show that the unconstrained theorie…

Compact objects in and beyond the standard model from nonperturbative vacuum scalarization Open
We consider a theory in which a real scalar field is Yukawa coupled to a fermion and has a potential with two nondegenerate vacua. If the coupling is sufficiently strong, a collection of N fermions deforms the true vacuum state, creating e…

Compact objects in and beyond the Standard Model from non-perturbative vacuum scalarization Open
We consider a theory in which a real scalar field is Yukawa-coupled to a fermion and has a potential with two non-degenerate vacua. If the coupling is sufficiently strong, a collection of N fermions deforms the true vacuum state, creating …

Fermion Soliton Stars with Asymmetric Vacua Open
Fermion soliton stars are a motivated model of exotic compact objects in which a nonlinear self-interacting real scalar field couples to a fermion via a Yukawa term, giving rise to an effective fermion mass that depends on the fluid proper…

A real scalar field coupled to a fermion via a Yukawa term can evade no-go theorems preventing solitonic solutions. For the first time, we study this model within general relativity without approximations, finding static and spherically sy…
