Asymptotic behavior of the warm inflation scenario with viscous pressure
Jose P. Mimoso, Ana Nunes, Diego Pavon
We analyze the dynamics of models of warm inflation with general dissipative effects. We consider phenomenological terms both for the inflaton decay rate and for viscous effects wi…
Constraining dark energy interacting models with WMAP
German Olivares, Fernando Atrio-Barandela, Diego Pavon
We determine the range of parameter space of an interacting quintessence (IQ) model that best fits the luminosity distance of type Ia supernovae data and the recent WMAP measuremen…
Holographic Dark Energy and Present Cosmic Acceleration
Diego Pavon, Winfried Zimdahl
We review the notion of holographic dark energy and assess its significance in the light of the well documented cosmic acceleration at the present time. We next propose a model of…
Soft coincidence in late acceleration
Sergio del campo, Ramon Herrera, Diego Pavon
We study the coincidence problem of late cosmic acceleration by assuming that the present ratio between dark matter and dark energy is a slowly varying function of the scale factor…
Dual interacting cosmologies and late accelerated expansion
Luis P. Chimento, Diego Pavon
In this paper we show that by considering a universe dominated by two interacting components a superaccelerated expansion can be obtained from a decelerated one by applying a dual…
Holographic dark energy and cosmic coincidence
Diego Pavon, Winfried Zimdahl
In this Letter we demonstrate that any interaction of pressureless dark matter with holographic dark energy, whose infrared cutoff is set by the Hubble scale, implies a constant ra…
