This paper presents a systematic treatment of the linear theory of scalar gravitational perturbations in the synchronous gauge and the conformal Newtonian (or longitudinal) gauge. It differs from others in the literature in that we give, in both gauges, a complete discussion of all particle species that are relevant to any flat cold dark matter (CDM), hot dark matter (HDM), or CDM+HDM models (including a possible cosmological constant). The particles considered include CDM, baryons, photons…

Cosmic Microwave Background Anisotropies in the Cold Dark Matter Model: A Covariant and Gauge-invariant Approach
We present a fully covariant and gauge-invariant calculation of the evolution of anisotropies in the cosmic microwave background radiation. We use the physically appealing covariant approach to
General primordial cosmic perturbation
We consider the most general primordial cosmological perturbation in a universe filled with photons, baryons, neutrinos, and a hypothetical cold dark matter (CDM) component within the framework of
Initial conditions for cold dark matter particles and General Relativity
We describe the irrotational dust component of the universe in terms of a relativistic gradient expansion and transform the resulting synchronous metric to a Newtonian coordinate system. The two
Signatures of relativistic neutrinos in CMB anisotropy and matter clustering
We present a detailed analytical study of ultrarelativistic neutrinos in cosmological perturbation theory and of the observable signatures of inhomogeneities in the cosmic neutrino background. We
Cosmological Perturbation Theory for streams of relativistic particles
Motion equations describing streams of relativistic particles and their properties are explored in detail in the framework of Cosmological Perturbation Theory. Those equations, derived in any metric
Cosmological evolution of warm dark matter fluctuations I: Efficient computational framework with Volterra integral equations
We study the complete cosmological evolution of dark matter (DM) density fluctuations for DM particles that decoupled being ultrarelativistic during the radiation dominated era which is the case of
Gravity of Cosmological Perturbations in the CMB
We, first, attempt to single out the measures of cosmological perturbations that are least afflicted by gauge artifacts and directly connect inhomogeneous large-scale evolution with microscopic
Describing massive neutrinos in cosmology as a collection of independent flows
A new analytical approach allowing to account for massive neutrinos in the non-linear description of the growth of the large-scale structure of the universe is proposed. Unlike the standard approach
Cosmological perturbations in elastic dark energy models
We discuss the general framework for a perfect continuum medium in cosmology and show that an interesting generalization of the fluids normally used is for the medium to have rigidity and, hence, be
Theoretical foundations of the reduced relativistic gas in the cosmological perturbed context
The Reduced Relativistic Gas (RRG) is a simplified version of the ideal relativistic gas, which assumes that all particles have the same momentum magnitude. Although this is a very idealized
