Strongly lensed candidates from the HSC transient survey
Dani C. -Y. Chao, James H. -H. Chan, Sherry H. Suyu +5
We present a lensed quasar search based on the variability of lens systems in the HSC transient survey. Starting from 101,353 variable objects with i-band photometry in the HSC tra…
HOLISMOKES -- III. Achromatic Phase of Strongly Lensed Type Ia Supernovae
S. Huber, S. H. Suyu, U. M. Noebauer +5
To use strongly lensed Type Ia supernovae (LSNe Ia) for cosmology, a time-delay measurement between the multiple supernova (SN) images is necessary. The sharp rise and decline of S…
Survey of Gravitationally lensed Objects in HSC Imaging (SuGOHI) -- VII. Discovery and Confirmation of Three Strongly Lensed Quasars
Anton T. Jaelani, Cristian E. Rusu, Issha Kayo +13
We present spectroscopic confirmation of three new two-image gravitationally lensed quasars, compiled from existing strong lens and X-ray catalogs. Images of HSC J091843.2702200…
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…
Multiple Images and Flux Ratio Anomaly of Fuzzy Gravitational Lenses
James H. H. Chan, Hsi-Yu Schive, Shing-Kwong Wong +2
Extremely light bosonic wave dark matter (DM) is an emerging dark matter candidate contesting the conventional cold dark matter paradigm and a model subject to intense scrutiny…
HOLISMOKES -- I. Highly Optimised Lensing Investigations of Supernovae, Microlensing Objects, and Kinematics of Ellipticals and Spirals
S. H. Suyu, S. Huber, R. Cañameras +10
We present the HOLISMOKES programme on strong gravitational lensing of supernovae as a probe of supernova (SN) physics and cosmology. We investigate the effects of microlensing on…
