Entropy perturbations in quartessence Chaplygin models
R. R. R. Reis, I. Waga, M. O. Calvao +1
We show that entropy perturbations can eliminate instabilities and oscillations, in the mass power spectrum of the quartessence Chaplygin models. Our results enlarge the current pa…

Observational Constraints on Chaplygin Quartessence: Background Results
Martin Makler, Sergio Quinet de Oliveira, Ioav Waga
We derive the constraints set by several experiments on the quartessence Chaplygin model (QCM). In this scenario, a single fluid component drives the Universe from a nonrelativisti…
