H0LiCOW III. Quantifying the effect of mass along the line of sight to the gravitational lens HE 0435-1223 through weighted galaxy counts
Cristian E. Rusu, Christopher D. Fassnacht, Dominique Sluse +8
Based on spectroscopy and multiband wide-field observations of the gravitationally lensed quasar HE 0435-1223, we determine the probability distribution function of the external co…
The effects of velocities and lensing on moments of the Hubble diagram
Edward Macaulay, Tamara M. Davis, Dario Scovacricchi +3
We consider the dispersion on the supernova distance-redshift relation due to peculiar velocities and gravitational lensing, and the sensitivity of these effects to the amplitude o…
H0LiCOW V. New COSMOGRAIL time delays of HE0435-1223: to 3.8% precision from strong lensing in a flat CDM model
V. Bonvin, F. Courbin, S. H. Suyu +15
We present a new measurement of the Hubble Constant H0 and other cosmological parameters based on the joint analysis of three multiply-imaged quasar systems with measured gravitati…
H0LiCOW IV. Lens mass model of HE 0435-1223 and blind measurement of its time-delay distance for cosmology
Kenneth C. Wong, Sherry H. Suyu, Matthew W. Auger +13
Strong gravitational lenses with measured time delays between the multiple images allow a direct measurement of the time-delay distance to the lens, and thus a measure of cosmologi…
H0LiCOW II. Spectroscopic survey and galaxy-group identification of the strong gravitational lens system HE0435-1223
D. Sluse, A. Sonnenfeld, N. Rumbaugh +15
Galaxies located in the environment or on the line of sight towards gravitational lenses can significantly affect lensing observables, and can lead to systematic errors on the meas…
Observational selection biases in time-delay strong lensing and their impact on cosmography
Thomas E. Collett, Steven D. Cunnington
Inferring cosmological parameters from time-delay strong lenses requires a significant investment of telescope time; it is therefore tempting to focus on the systems with the brigh…
Testing the speed of gravitational waves over cosmological distances with strong gravitational lensing
Thomas E. Collett, David Bacon
Probing the relative speeds of gravitational waves and light acts as an important test of General Relativity and alternative theories of gravity. Measuring the arrival time of grav…
The Dark Energy Survey: more than dark energy - an overview
Dark Energy Survey Collaboration, T. Abbott, F. B. Abdalla +138
This overview article describes the legacy prospect and discovery potential of the Dark Energy Survey (DES) beyond cosmological studies, illustrating it with examples from the DES…
