Global properties of the growth index: mathematical aspects and physical relevance
R. Calderon, D. Felbacq, R. Gannouji +2
We analyze the global behaviour of the growth index of cosmic inhomogeneities in an isotropic homogeneous universe filled by cold non-relativistic matter and dark energy (DE) with…
Deflection of Light by a Rotating Black Hole Surrounded by "Quintessence"
Prateek Sharma, Hemwati Nandan, Radouane Gannouji +2
We present a detailed analysis of a rotating black hole surrounded by "quintessence". This solution represents a fluid with a constant equation of state, , which can for example…
Large scale structures: from inflation to today: a brief report
Lina Castiblanco, Radouane Gannouji, Clément Stahl
We briefly review some selected topics gravitating around large scale structures. We derive from inflation the evolution of dark matter perturbations. The stress is put on the non-…
Global properties of the growth index of matter inhomogeneities in the universe
R. Calderon, D. Felbacq, R. Gannouji +2
We perform here a global analysis of the growth index behaviour from deep in the matter era till the far future. For a given cosmological model in GR or in modified gravity, th…
Pure Lovelock black hole in the dimension, , is stable
Radouane Gannouji, Yolbeiker Rodríguez Baez, Naresh Dadhich
In this paper we show that pure Lovelock static Schwarzschild's analogue black hole in dimensions , where is the degree of Lovelock polynomial action, is stable even th…
Energy extraction and particle acceleration around a rotating dyonic black hole in , gauged supergravity
Anik Rudra, Hemwati Nandan, Radouane Gannouji +2
In the present paper, we explore various gravitational aspects such as energy extraction (via the Penrose process and Superradiance), particle collisions around a ,…
