Can third- and fourth-order multipoles plus radial variation of iso-density ellipses explain the observed flux ratios in B1422231? YES, and a lesson learned from a TNG100 lensing galaxy sample
Ruizhe Feng, Dandan Xu, Dominique Sluse +3
Flux ratio anomalies in multiply-imaged quasar lenses are a long-standing issue. Using a classical system B1422+231 as a case study, we investigate how typical non-clumpy perturbat…
A deep learning model for the density profiles of subhaloes in IllustrisTNG
Luisa Lucie-Smith, Giulia Despali, Volker Springel
We present a machine-learning-based model for the total density profiles of subhaloes with masses in the IllustrisTNG100 simulation. T…
Not All Subhaloes Are Created Equal: Modelling the Diversity of Subhalo Density Profiles in TNG50
Felix M. Heinze, Giulia Despali, Ralf S. Klessen
In this work, we analyse the density profiles of subhaloes with masses M in the TNG50 simulation, with the aim of including baryonic ef…
The Three Hundred: relation
Atulit Srivastava, Weiguang Cui, Massimo Meneghetti +8
In this study, we investigate a recent finding based on strong lensing observations, which suggests that the sub-halos observed in clusters exhibit greater compactness compared to…
Detecting low-mass haloes with strong gravitational lensing I: the effect of data quality and lensing configuration
Giulia Despali, Simona Vegetti, Simon D. M. White +5
This paper aims to quantify how the lowest halo mass that can be detected with galaxy-galaxy strong gravitational lensing depends on the quality of the observations and the charact…
The inner density profile of an elliptical galaxy at z=1.15 from gravitational lensing
H. R. Stacey, C. M. O'Riordan, S. Vegetti +3
The density profiles of lensing galaxies are typically parameterised by singular power-law models with a logarithmic slope close to isothermal (). This is sufficient to fit th…
