ACT stands for Awkward Cosmology Theories
Loris Del Grosso, Alfredo Urbano, Marcello Ziccolella
Recent Atacama Cosmology Telescope (ACT) observations, combined with Planck, favor a scalar spectral index in tension with Starobinsky inflation. Two main strategies have been prop…
Cosmological Consequences of Unconstrained Gravity and Electromagnetism
Loris Del Grosso, David E Kaplan, Tom Melia +3
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…
Compact objects in and beyond the Standard Model from non-perturbative vacuum scalarization
Loris Del Grosso, Paolo Pani, Alfredo Urbano
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 collec…
