The gravitational wave (GW) event GW170817 from a binary neutron star merger together
with the electromagnetic counterpart showed that the speed of GWs ct is very close to that of …

Recent observations of Type 1a supernovae indicating an accelerating universe have once
more drawn attention to the possible existence, at the present epoch, of a small positive Λ …

We derive constraints on cosmological parameters and tests of dark energy models from the
combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave …

Quintessence is a canonical scalar field introduced to explain the late-time cosmic
acceleration. The cosmological dynamics of quintessence is reviewed, paying particular …

Recent cosmological observations suggest the existence of a positive cosmological constant
Λ with the magnitude Λ (Gℏ/c3)≈ 10− 123. This review discusses several aspects of the …

This is a review of the physics and cosmology of the cosmological constant. Focusing on
recent developments, I present a pedagogical overview of cosmology in the presence of a …

We consider the scenario emerging from the dynamics of a generalized Born-Infeld theory.
The equation of state describing this system is given in terms of the energy density ρ and …

The cosmological constant ADS Classic is now deprecated. It will be completely retired in
October 2019. This page will automatically redirect to the new ADS interface at that point …

We introduce a new cosmological diagnostic pair {r, s} called the Statefinder. The Statefinder
is a geometrical diagnostic and allows us to characterize the properties of dark energy in a …

Recently, a novel class of models for inflation has been found in which the inflationary
dynamics is driven solely by (noncanonical) kinetic terms rather than by potential terms. As …
