STRIDES: a 3.9 per cent measurement of the Hubble constant from the strong lens system DES J0408-5354
A. J. Shajib, S. Birrer, T. Treu +88
We present a blind time-delay cosmographic analysis for the lens system DES J04085354. This system is extraordinary for the presence of two sets of multiple images at different…
Constraints on the mass-concentration relation of cold dark matter halos with 11 strong gravitational lenses
Daniel Gilman, Xiaolong Du, Andrew Benson +3
The mass-concentration relation of dark matter halos reflects the assembly history of objects in hierarchical structure formation scenarios, and depends on fundamental quantities i…
Warm dark matter chills out: constraints on the halo mass function and the free-streaming length of dark matter with 8 quadruple-image strong gravitational lenses
Daniel Gilman, Simon Birrer, Anna Nierenberg +3
The free-streaming length of dark matter depends on fundamental dark matter physics, and determines the abundance and concentration of dark matter halos on sub-galactic scales. Usi…
Double dark matter vision: twice the number of compact-source lenses with narrow-line lensing and the WFC3 grism
A. M. Nierenberg, D. Gilman, T. Treu +9
The magnifications of compact-source lenses are extremely sensitive to the presence of low mass dark matter halos along the entire sight line from the source to the observer. Tradi…
COSMOGRAIL XVIII: time delays of the quadruply lensed quasar WFI2033-4723
V. Bonvin, M. Millon, J. H. H. Chan +26
We present new measurements of the time delays of WFI2033-4723. The data sets used in this work include 14 years of data taken at the 1.2m Leonhard Euler Swiss telescope, 13 years…
Testing the Nature of Dark Matter with Extremely Large Telescopes
Joshua D. Simon, Simon Birrer, Keith Bechtol +12
For nearly 40 years, dark matter has been widely assumed to be cold and collisionless. Cold dark matter models make fundamental predictions for the behavior of dark matter on small…
