Hydrodynamical Misner-Sharp Formulation for Gravitational Collapse in Scalar-Tensor Theories
Jose A. R. Cembranos, Luis Diaz-Gimenez
We study the problem of gravitational collapse in the context of scalar-tensor theories of Gravity. We introduce a new hydrodynamical formulation in the Einstein frame, inspired by…
A Consistent Path Integral Approach to Higher Derivative Oscillators
Jose A. R. Cembranos, Eric G. Hemon, Juan J. Sanz-Cillero
In this work, we study the Quantum Field Theory version of the higher derivative Pais-Uhlenbeck oscillator. We quantize canonically this system and construct its Fock space, as wel…
Sensitivity forecasts for gravitational-wave detectors to dark matter decaying into gravitons
Jose A. R. Cembranos, Álvaro Cendal
Dark matter may not be perfectly stable, and its decay could generate distinctive gravitational-wave signatures. In this work, we present model-independent predictions for the stoc…
Estimation of gravitational production uncertainties
Jose A. R. Cembranos, Luis J. Garay, Álvaro Parra-López +1
Cosmological production of scalar, non-minimally coupled dark matter depends on the specifics of the inflationary model under consideration. We analyze both Starobinsky inflation a…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
