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…
SHARP - V. Modelling gravitationally-lensed radio arcs imaged with global VLBI observations
C. Spingola, J. P. McKean, M. W. Auger +4
We present milliarcsecond (mas) angular resolution observations of the gravitationally lensed radio source MG J0751+2716 (at z=3.2) obtained with global Very Long Baseline Interfer…
Testing Convolutional Neural Networks for finding strong gravitational lenses in KiDS
C. E. Petrillo, C. Tortora, S. Chatterjee +7
Convolutional Neural Networks (ConvNets) are one of the most promising methods for identifying strong gravitational lens candidates in survey data. We present two ConvNet lens-find…
KiDS-SQuaD: The KiDS Strongly lensed Quasar Detection project
C. Spiniello, A. Agnello, N. R. Napolitano +11
New methods have been recently developed to search for strong gravitational lenses, in particular lensed quasars, in wide-field imaging surveys. Here, we compare the performance of…
Robust Foregrounds Removal for 21-cm Experiments
F. Mertens, A. Ghosh, L. V. E. Koopmans
Direct detection of the Epoch of Reionization via the redshifted 21-cm line will have unprecedented implications on the study of structure formation in the early Universe. To fulfi…
