Cosmology with Supernova Encore in the lensing cluster MACS J01382155 -- Spectroscopy with MUSE
G. Granata, G. B. Caminha, S. Ertl +9
We present a spectroscopic analysis of MACS J01382155, at , the first galaxy cluster hosting two strongly-lensed supernovae (SNe), Requiem and Encore, providing us with…
HOLISMOKES XV. Search for strong gravitational lenses combining ground-based and space-based imaging
A. Melo, R. Cañameras, S. Schuldt +4
In the past, researchers have mostly relied on single-resolution images from individual telescopes to detect gravitational lenses. We propose a search for galaxy-scale lenses that,…
Euclid: Searches for strong gravitational lenses using convolutional neural nets in Early Release Observations of the Perseus field
R. Pearce-Casey, B. C. Nagam, J. Wilde +204
The Euclid Wide Survey (EWS) is predicted to find approximately 170 000 galaxy-galaxy strong lenses from its lifetime observation of 14 000 deg^2 of the sky. Detecting this many le…
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…
Improved model of the Supernova Refsdal cluster MACS J1149.5+2223 thanks to VLT/MUSE
S. Schuldt, C. Grillo, G. B. Caminha +9
We present new VLT/MUSE observations of the Hubble Frontier Field (HFF) galaxy cluster MACS J1149.5+2223, lensing the well-known supernova "Refsdal" into multiple images, which ena…
Augmenting the power of time-delay cosmography in lens galaxy clusters by probing their member galaxies. II. Cosmic chronometers
P. Bergamini, S. Schuldt, A. Acebron +9
We present a novel approach to measuring the expansion rate and the geometry of the Universe, which combine time-delay cosmography in lens galaxy clusters with pure samples of 'cos…
