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 …

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 …

Employing the modified entropy–area relation suggested by Tsallis and Cirto [1], and the
holographic hypothesis, a new holographic dark energy (HDE) model is proposed …

The rapidly expanding field of galaxy formation lies at the interface between astronomy,
particle physics, and cosmology. Covering diverse topics from these disciplines, all of which …

We report measurements of the mass density, Ω $\mathstrut {_ {M}} $, and cosmological-
constant energy density, Ω $\mathstrut {_ {{\Lambda}}} $, of the universe based on the …

We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the
redshift range 0.16≤ z≤ 0.62. The luminosity distances of these objects are determined by …

Friedmann–Robertson–Walker universes with a presently large fraction of the energy
density stored in an X-component with wX<-1/3, are considered. We find all the critical points …

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 …

ABSTRACT The High-Z Supernova Search is an international collaboration to discover and
monitor Type Ia supernovae (SNe Ia) at z> 0.2 with the aim of measuring cosmic …

We present a new compilation of Type Ia supernovae (SNe Ia), a new data set of low-redshift
nearby-Hubble-flow SNe, and new analysis procedures to work with these heterogeneous …
