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…
H0LiCOW I. Lenses in COSMOGRAIL's Wellspring: Program Overview
S. H. Suyu, V. Bonvin, F. Courbin +21
Strong gravitational lens systems with time delays between the multiple images allow measurements of time-delay distances, which are primarily sensitive to the Hubble constant that…
Computational issues in chemo-dynamical modelling of the formation and evolution of galaxies
Yves Revaz, Alexis Arnaudon, Matthew Nichols +2
Chemo-dynamical N-body simulations are an essential tool for understanding the formation and evolution of galaxies. As the number of observationally determined stellar abundances c…
