TDCOSMO XXVIII. The Hubble constant from the quadruply lensed quasar J1537 $-$ 3010 with precise time delays

A. Galan, A. G. Schweinfurth, S. H. Suyu +21

We present the first measurement of the Hubble constant ( $H_{0}$ ) from the quadruply-lensed quasar J1537 $-$ 3010, which has optically-measured time delays at $\sim 2%$ precision. We…

HOLISMOKES XIX: SN 2025wny at $z = 2$ , 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…

J1721+8842: The first Einstein zig-zag lens

F. Dux, M. Millon, C. Lemon +16

We report the discovery of the first example of an Einstein zig-zag lens, an extremely rare lensing configuration. In this system, J1721+8842, six images of the same background qua…
