The Magnificent Five Images of Supernova Refsdal: Time Delay and Magnification Measurements
Martin Raoul Robert Millon, Mathilde Jauzac, Vivien François Bonvin, Anja Von der Linden
In late 2014, four images of Supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster field. Following the images' discovery, the SN was predicted to reappear wi ...
IOP Publishing Ltd2023Next generation modeling techniques for strong gravitational lensing and measuring the Hubble constant
For many years, observations of the Universe suggest a series problems with our theoretical models, particularly its dark energy and dark matter components. Fortunately, the Universe also provides us with a tool to solve these problems, called strong gravi ...
EPFL2022Blue-shift ultrasensitivity using rhombus-shaped plasmonic crystal on Si3N4 membrane
Bahareh Ghadiani, Dordaneh Etezadi, Yasaman Jahani, Ershad Mohammadi, Foziyeh Sohrabi, Mahdi Tamizifar
Harnessing ultrasensitivity from optical structures to detect tiny changes in the targeted samples is the main goal of scientists in the field of sensor design. In this study, an uncommon rhombus-shape plasmonic structure is proposed for providing blue-shi ...
OPTICAL SOC AMER2020TDCOSMO. IV. Hierarchical time-delay cosmography - joint inference of the Hubble constant and galaxy density profiles
Frédéric Courbin, Martin Raoul Robert Millon, Aymeric Alexandre Galan, Adriano Agnello
The H0LiCOWcollaboration inferred via strong gravitational lensing time delays a Hubble constant value of H0 = 73 :3+1:7 1:8 km s 1 Mpc 1, describing deflector mass density profiles by either a power-law or stars (constant mass-to-light ratio) plus standar ...
