TDCOSMO XXVIII. The Hubble constant from the quadruply lensed quasar J15373010 with precise time delays
A. Galan, A. G. Schweinfurth, S. H. Suyu +21
We present the first measurement of the Hubble constant () from the quadruply-lensed quasar J15373010, which has optically-measured time delays at precision. We…
HOLISMOKES XX. Lens models of binary lens galaxies with five images of Supernova Winny
L. R. Ecker, A. G. Schweinfurth, R. Saglia +13
Strongly lensed supernovae (SNe) provide a powerful way to study cosmology, SNe and galaxies. Modelling the lens system is key to extracting astrophysical and cosmological informat…
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…
A long-lasting eruption heralds SN 2023ldh, a clone of SN 2009ip
A. Pastorello, A. Reguitti, L. Tartaglia +46
We discuss the results of the spectroscopic and photometric monitoring of the type IIn supernova (SN) 2023ldh. Survey archive data show that the SN progenitor experienced some erra…
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…
