  • DEEP LEARNING UNRESOLVED LENSED LIGHT CURVES 
    Denissenya, Mikhail; Linder, Eric V (Monthly Notices of the Royal Astronomical Society, 2022)
    Gravitationally lensed sources may have unresolved or blended multiple images, and for time varying sources, the light curves from individual images can overlap. We use convolutional neural nets to both classify the light ...
  • OUT OF ONE, MANY: DISTINGUISHING TIME DELAYS FROM LENSED SUPERNOVAE 
    Denissenya, Mikhail; Bag, Satadru; Kim, Alex G; Linder, Eric V; Shafieloo, Arman (Monthly Notices of the Royal Astronomical Society, 2022)
    Gravitationally lensed Type Ia supernovae are an emerging probe with great potential for constraining dark energy, spatial curvature, and the Hubble constant. The multiple images and their time delayed and magnified fluxes ...
