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

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 ...

H0LiCOW-I. H-0 Lenses in COSMOGRAIL's Wellspring: program overview

Frédéric Courbin, Georges Meylan, Malte Tewes, Vivien François Bonvin, Olga Tihhonova, Adriano Agnello

Strong gravitational lens systems with time delays between the multiple images allow measurements of time-delay distances, which are primarily sensitive to the Hubble constant that is key to probing dark energy, neutrino physics and the spatial curvature o ...

H0LiCOW. VI. Testing the fidelity of lensed quasar host galaxy reconstruction

Frédéric Courbin, Adriano Agnello

The empirical correlation between the mass of a supermassive black hole (M-BH) and its host galaxy properties is widely considered to be an evidence of their co-evolution. A powerful way to test the co-evolution scenario and learn about the feedback proces ...

Models of the strongly lensed quasar DES J0408-5354

Eduardo Sanchez, Frédéric Courbin, Georges Meylan, 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 ...

Discovery of the Lensed Quasar System DES J0408-5354

Eduardo Sanchez, Frédéric Courbin, Georges Meylan, Hung-Hsu Chan, Adriano Agnello

We report the discovery and spectroscopic confirmation of the quad-like lensed quasar system DES J0408-5354 found in the Dark Energy Survey (DES) Year 1 (Y1) data. This system was discovered during a search for DES Y1 strong lensing systems using a method ...

Discovery of two gravitationally lensed quasars in the Dark Energy Survey

Eduardo Sanchez, Frédéric Courbin, Georges Meylan, Yi Zhang, Adriano Agnello

We present spectroscopic confirmation of two new gravitationally lensed quasars, discovered in the Dark Energy Survey (DES) and Wide-field Infrared Survey Explorer (WISE) based on their multiband photometry and extended morphology in DES images. Images of ...
