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…

Resolving on 100 pc scales the UV-continuum in Lyman- emitters between redshift 2 to 3 with gravitational lensing

E. Ritondale, M. W. Auger, S. Vegetti +1

We present a study of seventeen LAEs at redshift 23 gravitationally lensed by massive early-type galaxies (ETGs) at a mean redshift of approximately 0.5. Using a fully Bayesia…

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…

A novel 3D technique to study the kinematics of lensed galaxies

Francesca Rizzo, Simona Vegetti, Filippo Fraternali +1

We present a 3D Bayesian method to model the kinematics of strongly lensed galaxies from spatially-resolved emission-line observations. This technique enables us to simultaneously…

Constraining the microlensing effect on time delays with new time-delay prediction model in measurements

Geoff C. -F. Chen, James H. H. Chan, Vivien Bonvin +14

Time-delay strong lensing provides a unique way to directly measure the Hubble constant (). The precision of the measurement depends on the uncertainties in the time…
