Laser-based manufacturing of freeform glass micro-optics through topological transformation
Glass has been the material of choice for making optical elements, in large part due to its intrinsic properties: a temperature-dependent viscosity, which enables shaping the material into a broad variety of functional and artistic glassware. Silica glass ...
EPFL2024Searching for Strong Gravitational Lenses
Frédéric Courbin, Cameron Alexander Campbell Lemon
Strong gravitational lenses provide unique laboratories for cosmological and astrophysical investigations, but they must first be discovered - a task that can be met with significant contamination by other astrophysical objects and asterisms. Here we revie ...
Dordrecht2024In situ detection of multitarget impurities on contact lens by electrochemical scanning probe
Fang Liu, Tzu-En Lin, Yingdi Zhu
Identifying multitarget impurities on contact lenses is challenging because traditional methods such as polymerase chain reaction cannot be used on the unknown target. Other sampling methods often require expensive antibodies or dyes. Therefore, this resea ...
ELSEVIER SCIENCE SA2023Repair! Reclaiming Berlin’s Workers’ Housing through Collaborative Transformation
The phase of economic and humanitarian emergencies after the Great War functioned as a laboratory for architects to develop quick, rational responses. But socialist visions became stuck in privatization, and values of a bygone society were maintained by pr ...
2023The impact of human expert visual inspection on the discovery of strong gravitational lenses
Frédéric Courbin, Benjamin Yvan Alexandre Clement, Martin Raoul Robert Millon, Eric Gérard Guy Paic, Hung-Hsu Chan, Karina Alexandra Rojas Olate, Rémy Elie Joseph, Elodie Marie Charlène Savary, Yue Pan
We investigate the ability of human 'expert' classifiers to identify strong gravitational lens candidates in Dark Energy Survey like imaging. We recruited a total of 55 people that completed more than 25 per cent of the project. During the classification t ...
OXFORD UNIV PRESS2023LensWatch. I. Resolved HST Observations and Constraints on the Strongly Lensed Type Ia Supernova 2022qmx ("SN Zwicky")
Frédéric Courbin, Adriano Agnello
Supernovae (SNe) that have been multiply imaged by gravitational lensing are rare and powerful probes for cosmology. Each detection is an opportunity to develop the critical tools and methodologies needed as the sample of lensed SNe increases by orders of ...
IOP Publishing Ltd2023The ellipticity parameterization for an NFW profile: An overlooked angular structure in strong lens modeling
Galaxy-scale gravitational lenses are often modeled with two-component mass profiles where one component represents the stellar mass and the second is a Navarro Frenk White (NFW) profile representing the dark matter. Outside of the spherical case, the NFW ...

The strong clinical demand for more accurate and personalized health monitoring technologies has called for the development of additively manufactured wearable devices. While the materials palette for additive manufacturing continues to expand, the integra ...
2023Gravitationally lensed quasars in Gaia - IV. 150 new lenses, quasar pairs, and projected quasars
Frédéric Courbin, Aymeric Alexandre Galan, Cameron Alexander Campbell Lemon, Adriano Agnello
We report the spectroscopic follow-up of 175 lensed quasar candidates selected using Gaia Data Release 2 observations following Paper III of this series. Systems include 86 confirmed lensed quasars and a further 17 likely lensed quasars based on imaging an ...
OXFORD UNIV PRESS2023Microwave Metalens Antennas
Recently, there has been growing interest in the use of metamaterial (MTM)-based lenses, also known as metalenses, as innovative antenna technology. Increasingly widespread applications of metalenses in modern microwave communication and sensing systems ha ...
