Abstract: In this paper, we use the latest observations of quasars covering the redshift range of $$0.04<z<5.1$$ 0.04 < z < 5.1 to investigate a series of Chaplygin gas models as candidates for unified dark matter and dark energy. Based on different combinations of available standard candle and standard ruler data, we put constraints on the generalized Cha… Show more

“…In future studies we will thereby take further steps in that direction, focusing on the different types of generalized Chaplygin gas models as discussed in Ref. [11]. In addition, as carried out in the case of boson stars [101], it would be interesting to employ a Fisher matrix analysis in order to distinguish dark energy stars from black holes and neutron stars from tidal interactions in inspiraling binary systems.…”

“…As it is well known, a possible alternative to the Phantom and Quintessence fields is the Chaplygin gas, where the EoS assumes the form p r = −B/ρ, with B being a positive constant (given in m −4 units). In fact, it was argued that such gas could provide a solution to unify the effects of dark matter in the early times and dark energy in late times [4,11]. Although the literature provides a more generalized version for such EoS in the context of the Friedmann-Lemaître-Robertson-Walker Universe [5][6][7][73][74][75][76][77], here we will use the simplest form plus a linear term corresponding to a barotropic fluid, namely…”
