TDCOSMO. XXIII. Measurement of the Hubble constant from the doubly lensed quasar HE1104-1805
Eric Paic, Frédéric Courbin, Christopher D. Fassnacht +18
Time-delay cosmography leverages strongly lensed quasars to measure the Universe's current expansion rate, H_0, independently from other methods. While the latest TDCOSMO results 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…
Early galaxy evolution: The complex interstellar medium distribution of the z~7 galaxy A1689-zD1
Kirsten K. Knudsen, Darach Watson, Johan Richard +12
We observed the gravitationally lensed () galaxy A1689-zD1 at in bands 3, 6, and 8 of the Atacama Large Millimeter/submillimeter Array. These high-resoluti…
Cosmography from accurate mass modeling of the lens group SDSS J0100+1818: five sources at three different redshifts
A. Bolamperti, C. Grillo, G. B. Caminha +6
Systems where multiple sources at different redshifts are strongly lensed by the same deflector allow one to directly investigate the evolution of the angular diameter distances wi…
Origin of the strong sodium absorption of the lensed supernova 2016geu at z=0.4
Christa Gall, Jens Hjorth, Lise Christensen +7
The origin of strong sodium absorption, which has been observed for a few nearby Type Ia supernovae (SNe Ia), remains elusive. Here we analyse two high-signal-to-noise, intermediat…
Strong-lensing and kinematic analysis of CASSOWARY 31: can strong lensing constrain the masses of multi-plane lenses?
H. Wang, R. Canameras, S. H. Suyu +4
We present a mass measurement for the secondary lens along the line of sight (LoS) in the multi-plane strong lens modeling of the group-scale lens CASSOWARY 31 (CSWA 31). The secon…
TDCOSMO IV: Hierarchical time-delay cosmography -- joint inference of the Hubble constant and galaxy density profiles
S. Birrer, A. J. Shajib, A. Galan +24
The H0LiCOW collaboration inferred via gravitational lensing time delays a Hubble constant km s, describing deflector mass density pro…
Extreme magnification of a star at redshift 1.5 by a galaxy-cluster lens
Patrick L. Kelly, Jose M. Diego, Steven Rodney +42
Galaxy-cluster gravitational lenses can magnify background galaxies by a total factor of up to ~50. Here we report an image of an individual star at redshift z=1.49 (dubbed "MACS J…
Dark matter fraction of low-mass cluster members probed by galaxy-scale strong lensing
W. G. Parry, C. Grillo, A. Mercurio +8
We present a strong lensing system, composed of 4 multiple images of a source at z = 2.387, created by two lens galaxies, G1 and G2, belonging to the galaxy cluster MACS J1115.9+01…
MUSE integral-field spectroscopy towards the Frontier Fields Cluster Abell S1063: I. Data products and redshift identifications
W. Karman, K. I. Caputi, C. Grillo +11
We present the first observations of the Frontier Fields Cluster Abell S1063 taken with the newly commissioned Multi Unit Spectroscopic Explorer (MUSE) integral field spectrograph.…
Dark matter-rich early-type galaxies in the CASSOWARY 5 strong lensing system
C. Grillo, L. Christensen
We study the strong gravitational lensing system number 5 identified by the CASSOWARY survey. In this system, a source at redshift 1.069 is lensed into four detected images by two…
