The Suyama-Yamaguchi consistency relation in the presence of vector fields
Juan P. Beltran Almeida, Yeinzon Rodriguez, Cesar A. Valenzuela-Toledo
We consider inflationary models in which vector fields are responsible for part or eventually all of the primordial curvature perturbation ζ. Such models are phenomenologically int…
Analytical Potentials for Flat Galaxies with Spheroidal Halos
G. A. González, J. I. Reina
A family of analytical potential-density pairs for flat galaxies with spheroidal halos is presented. The potential are obtained by means of the sum of two independent terms: a pote…
Feynman-like Rules for Calculating n-Point Correlators of the Primordial Curvature Perturbation
Cesar A. Valenzuela-Toledo, Yeinzon Rodriguez, Juan P. Beltran Almeida
A diagrammatic approach to calculate n-point correlators of the primordial curvature perturbation ζwas developed a few years ago following the spirit of the Feynman rules in Quantu…
Stability of equatorial circular geodesics in static axially symmetric spacetimes
Guillermo A. González, Framsol López-Suspes
A general study of the stability of equatorial circular orbits in static axially symmetric gravitating systems is presented. Important circular geodesics as the marginally stable o…
