HOLISMOKES: II. Identifying galaxy-scale strong gravitational lenses in Pan-STARRS using convolutional neural networks

Elodie Marie Charlène Savary, Karina Alexandra Rojas Olate, Cameron Alexander Campbell Lemon

We present a systematic search for wide-separation (with Einstein radius theta(E)greater than or similar to 1.5 ''), galaxy-scale strong lenses in the 30 000 deg(2) of the Pan-STARRS 3 pi survey on the Northern sky. With long time delays of a few days to w ...

STRIDES: a 3.9 per cent measurement of the Hubble constant from the strong lens system DES J0408-5354

Georges Meylan, Frédéric Courbin, Vivien François Bonvin, Martin Raoul Robert Millon, Aymeric Alexandre Galan, Cameron Alexander Campbell Lemon

We present a blind time-delay cosmographic analysis for the lens system DES J0408-5354. This system is extraordinary for the presence of two sets of multiple images at different redshifts, which provide the opportunity to obtain more information at the cos ...

The STRong lensing Insights into the Dark Energy Survey (STRIDES) 2016 follow-up campaign - I. Overview and classification of candidates selected by two techniques

Eduardo Sanchez, Georges Meylan, Frédéric Courbin, Joo Yeon Kim, Craig Matthew Smith, Riccardo Agnello, Augusto Martins Lima, Hung-Hsu Chan, Karina Alexandra Rojas Olate, Cameron Alexander Campbell Lemon, Adriano Agnello

The primary goals of the STRong lensing Insights into the Dark Energy Survey (STRIDES) collaboration are to measure the dark energy equation of state parameter and the free streaming length of dark matter. To this aim, STRIDES is discovering strongly lense ...

Models of the strongly lensed quasar DES J0408-5354

Eduardo Sanchez, Georges Meylan, Frédéric Courbin, Vivien François Bonvin, Hung-Hsu Chan, Cameron Alexander Campbell Lemon, Adriano Agnello

We present detailed modelling of the recently discovered, quadruply lensed quasar J0408-5354, with the aim of interpreting its remarkable configuration: besides three quasar images (A, B, D) around the main deflector (G1), a fourth image (C) is significant ...
