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…
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…
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…
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.…
