COSMOLOGY WITH STRONG-LENSING SYSTEMS

In this paper, we assemble a catalog of 118 strong gravitational lensing systems from the Sloan Lens ACS Survey, BOSS emission-line lens survey, Lens Structure and Dynamics, and Strong Lensing Legacy…

Ultra-compact structure in intermediate-luminosity radio quasars: building a sample of standard cosmological rulers and improving the dark energy constraints up to z ~ 3

Context. Ultra-compact structure in radio sources (especially in quasars that can be observed up to very high redshifts), with milliarcsecond angular sizes measured by very-long-baseline…

A new white dwarf constraint on the rate of change of the gravitational constant

In this paper we derive a bound on the rate of change of the gravitational constant G based on observations of the pulsating white dwarf G117-B15A. This star is a ZZ Ceti pulsator which has been…

Exploring cosmic origins with CORE: Survey requirements and mission design

The requirements for a future CMB polarisation survey addressing these scientific objectives are listed, and the design drivers of the COREmfive space mission proposed to ESA in answer to the "M5" call for a medium-sized mission are discussed.

Precision cosmology from future lensed gravitational wave and electromagnetic signals

It is demonstrated that the time delay between lensed gravitational wave signals and their electromagnetic counterparts can reduce the uncertainty in the Hubble constant.

Constraints on cosmological models from strong gravitational lensing systems

Strong lensing has developed into an important astrophysical tool for probing both cosmology and galaxies (their structure, formation, and evolution). Using the gravitational lensing theory and…

Measuring the speed of light with ultra-compact radio quasars

In this paper, based on a 2.29 GHz VLBI all-sky survey of 613 milliarcsecond ultra-compact radio sources with 0.0035<z<3.787, we describe a method of identifying the sub-sample which can serve as…

IS THERE EVIDENCE FOR DARK ENERGY EVOLUTION?

Recently, Sahni et al. combined two independent measurements of H(z) from BAO data with the value of the Hubble constant H 0 = H ( z = 0 ) ?> in order to test the cosmological constant hypothesis by…

Strong gravitational lensing of gravitational waves from double compact binaries—perspectives for the Einstein Telescope

Gravitational wave (GW) experiments are entering their advanced stage which should soon open a new observational window on the Universe. Looking into this future, the Einstein Telescope (ET) was…
