Euclid Quick Data Release (Q1). The Strong Lensing Discovery Engine F -- Bright and low-redshift strong lenses
Euclid Collaboration, L. R. Ecker, M. Fabricius +346
We present 72 additional galaxy-galaxy strong lenses that complement the sample discovered in the Euclid Quick Release 1 data (63.1 deg^2) of the Strong Lens Discovery Engine (SLDE…
The impact of human expert visual inspection on the discovery of strong gravitational lenses
Karina Rojas, Thomas E. Collett, Daniel Ballard +53
We investigate the ability of human 'expert' classifiers to identify strong gravitational lens candidates in Dark Energy Survey like imaging. We recruited a total of 55 people that…
Hubble Asteroid Hunter: II. Identifying strong gravitational lenses in HST images with crowdsourcing
Emily O. Garvin, Sandor Kruk, Claude Cornen +3
The Hubble Space Telescope (HST) archives constitute a rich dataset of high resolution images to mine for strong gravitational lenses. While many HST programs specifically target s…
The lens SW05 J143454.4+522850: a fossil group at redshift 0.6?
Philipp Denzel, Onur Çatmabacak, Jonathan P. Coles +8
Fossil groups are considered the end product of natural galaxy group evolution in which group members sink towards the centre of the gravitational potential due to dynamical fricti…
Survey of Gravitationally-lensed Objects in HSC Imaging (SuGOHI). VI. Crowdsourced lens finding with Space Warps
Alessandro Sonnenfeld, Aprajita Verma, Anupreeta More +19
Strong lenses are extremely useful probes of the distribution of matter on galaxy and cluster scales at cosmological distances, but are rare and difficult to find. The number of cu…
Models of gravitational lens candidates from Space Warps CFHTLS
Rafael Küng, Prasenjit Saha, Ignacio Ferreras +9
We report modelling follow-up of recently-discovered gravitational-lens candidates in the Canada France Hawaii Telescope Legacy Survey. Lens modelling was done by a small group of…
AGN photoionization of gas in companion galaxies as a probe of AGN radiation in time and direction
William C. Keel, Vardha N. Bennert, Anna Pancoast +9
We consider AGN photoionization of gas in companion galaxies (cross-ionization) as a way to sample the intensity of AGN radiation in both direction and time, independent of the gas…
Space Warps: I. Crowd-sourcing the Discovery of Gravitational Lenses
Philip J. Marshall, Aprajita Verma, Anupreeta More +20
We describe Space Warps, a novel gravitational lens discovery service that yields samples of high purity and completeness through crowd-sourced visual inspection. Carefully produce…
Space Warps II. New Gravitational Lens Candidates from the CFHTLS Discovered through Citizen Science
Anupreeta More, Aprajita Verma, Philip J. Marshall +18
We report the discovery of 29 promising (and 59 total) new lens candidates from the CFHT Legacy Survey (CFHTLS) based on about 11 million classifications performed by citizen scien…
Gravitational lens modelling in a citizen science context
Rafael Küng, Prasenjit Saha, Anupreeta More +9
We develop a method to enable collaborative modelling of gravitational lenses and lens candidates, that could be used by non-professional lens enthusiasts. It uses an existing free…
