Non-relativistic Cosmological Collider Signals
Matheus C. Ferreira, Felipe T. Falciano, F. T. Falciano
We investigate a non-relativistic realization of the boostless cosmological collider in a scenario where inflationary interactions are mediated by a massive tilted-ghost spectator…
Amplifying the Cosmological Collider with Ghost Spectators
Matheus Curado Ferreira, F. T. Falciano, Guilherme L. Pimentel
Ghost inflation is a well-known framework in which cosmological fluctuations can generate enhanced primordial non-Gaussianity, typically of the equilateral type. In its original fo…
Exceeding the conformal limit inside rotating neutron stars: Implications to modified theories of gravity
Raissa F. P. Mendes, Caroline F. Sodré, Felipe T. Falciano
At the supranuclear densities achieved inside a neutron star, matter may exhibit extreme properties. In particular, it may be the case that a suitable average of the speed of sound…
