Constraining the mass density of free-floating black holes using razor-thin lensing arcs
Uddipan Banik, Frank C. van den Bosch, Michael Tremmel +5
Strong lensing of active galactic nuclei in the radio can result in razor-thin arcs, with a thickness of less than a milli-arcsecond, if observed at the resolution achievable with…
Low-mass halo perturbations in strong gravitational lenses at redshift z0.5 are consistent with CDM
E. Ritondale, S. Vegetti, G. Despali +3
We use a sample of 17 strong gravitational lens systems from the BELLS GALLERY survey to quantify the amount of low-mass dark matter haloes within the lensing galaxies and along th…
The interplay of Self-Interacting Dark Matter and baryons in shaping the halo evolution
Giulia Despali, Martin Sparre, Simona Vegetti +3
We use high-resolution hydrodynamical simulation to test the difference of halo properties in cold dark matter (CDM) and a self-interacting dark matter (SIDM) scenario with a const…
Time Delay Lens Modeling Challenge: I. Experimental Design
Xuheng Ding, Tommaso Treu, Anowar J. Shajib +11
Strong gravitational lenses with measured time delay are a powerful tool to measure cosmological parameters, especially the Hubble constant (). Recent studies show that by com…
Constraining sterile neutrino cosmologies with strong gravitational lensing observations at redshift z~0.2
S. Vegetti, G. Despali, M. R. Lovell +1
We use the observed amount of subhaloes and line-of-sight dark matter haloes in a sample of 11 gravitational lens systems from the Sloan Lens ACS Survey to constrain the free-strea…
