Effects of massive spin-2 fields on gravitational wave propagation
Jose A. R. Cembranos, Álvaro Cendal, Hector Villarrubia-Rojo
Massive spin-2 fields in addition to the standard massless graviton arise naturally in extensions of general relativity, such as massive bigravity or models with extra dimensions.…
LHC constraints on hidden gravitons
J. A. R. Cembranos, R. L. Delgado, H. Villarrubia-Rojo
We analyze LHC data in order to constrain the parameter space of new spin-2 particles universally coupled to the energy-momentum tensor. These new hypothetical particles are the so…
Magnetic fields from cosmological bulk flows
J. A. R. Cembranos, A. L. Maroto, H. Villarrubia-Rojo
We explore the possibility that matter bulk flows could generate the required vorticity in the electron-proton-photon plasma to source cosmic magnetic fields through the Harrison m…
Non-comoving Cosmology
J. A. R. Cembranos, A. L. Maroto, H. Villarrubia-Rojo
One of the fundamental assumptions of the standard CDM cosmology is that, on large scales, all the matter-energy components of the Universe share a common rest frame. This seems…
Constraints on anharmonic corrections of Fuzzy Dark Matter
J. A. R. Cembranos, A. L. Maroto, S. J. Núñez Jareño +1
The cold dark matter (CDM) scenario has proved successful in cosmology. However, we lack a fundamental understanding of its microscopic nature. Moreover, the apparent disagreement…
Constraints on hidden gravitons from fifth-force experiments and stellar energy loss
J. A. R. Cembranos, A. L. Maroto, H. Villarrubia-Rojo
We study different phenomenological signatures associated with new spin-2 particles. These new degrees of freedom, that we call hidden gravitons, arise in different high-energy the…
