TDCOSMO XXV: A "soup-to-nuts" 6.5% measurement strong lensing and dynamics with a maximally flexible mass sheet
William Sheu, Tommaso Treu, Martin Millon +16
We present a blind time-delay cosmography measurement of the Hubble constant based on the quadruply imaged quasar SDSSJ1433+6007. Our analysis combines deep Hubble Space Tele…

Time-delay and lens galaxy redshift in the doubly imaged quasar PS J2305+3714
O. A. Burkhonov, V. N. Shalyapin, A. V. Sergeyev +6
We present results from a seven-season (2018-2024) monitoring campaign of the gravitationally lensed quasar system PS J2305+3714 using the 1.5-m Maidanak Telescope in the optical R…

HOLISMOKES XIX: SN 2025wny at , the first strongly lensed superluminous supernova
Stefan Taubenberger, Ana Acebron, Raoul Cañameras +45
We present imaging and spectroscopic observations of supernova SN 2025wny, associated with the lens candidate PS1 J0716+3821. Photometric monitoring from the Lulin and Maidanak obs…
