H0LiCOW VI. Testing the fidelity of lensed quasar host galaxy reconstruction
Xuheng Ding, Kai Liao, Tommaso Treu +11
The empirical correlation between the mass of a super-massive black hole (MBH) and its host galaxy properties is widely considered to be evidence of their co-evolution. A powerful…
The inner structure of early-type galaxies in the Illustris simulation
Dandan Xu, Volker Springel, Dominique Sluse +5
Early-type galaxies provide unique tests for the predictions of the cold dark matter cosmology and the baryonic physics assumptions entering models for galaxy formation. In this wo…
Merger-driven evolution of the effective stellar initial mass function of massive early-type galaxies
Alessandro Sonnenfeld, Carlo Nipoti, Tommaso Treu
The stellar initial mass function (IMF) of early-type galaxies is the combination of the IMF of the stellar population formed in-situ and that of accreted stellar populations. Usin…
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…
