Detection of a dark matter subhalo in the strongly lensed system PJ011646

Aristeidis Amvrosiadis, James W. Nightingale, Qiuhan He +12

We present a strong lensing analysis of the system PJ011646 using high-resolution (0.1 arcsec) Atacama Large Millimeter/submillimeter Array (ALMA) dust-continuum observations…

Milky-Way-like stars in a galaxy core 8 billion years ago revealed by gravitational lensing

Quirino D'Amato, Filippo Mannucci, Alessandro Sonnenfeld +40

The assembly of stellar-dominated cores in elliptical galaxies is key to understanding how cosmic structures evolved. Gravitational lensing offers unique insights into the nature o…

The "Little Dark Dot": Evidence for Self-interacting Dark Matter in the Strong Lens SDSS J0946+1006?

Shubo Li, Ran Li, Kaihao Wang +13

Previous studies, based on precise modeling of a gravitationally lensing image, have identified what may be an extremely compact, dark perturber in the well-known lensing system SD…

Pixel-level modelling of group-scale strong lens CASSOWARY 19

Hengkai Ding, Yiping Shu, Yun Chen +6

We present the first high-precision model for the group-scale strong lensing system CASSOWARY 19 (CSWA19), utilising images from the Hubble Space Telescope (HST). Sixteen member ga…

The COSMOS-Web Lens Survey (COWLS) II: depth, resolution, and NIR coverage from JWST reveal 17 spectacular lenses

Guillaume Mahler, James W. Nightingale, Natalie B. Hogg +27

The COSMOS-Web Lens Survey (COWLS) presents the first systematic search for strong gravitational lenses in the COSMOS-Web field using data from the \textit{James Webb} Space Telesc…

The COSMOS-Web Lens Survey (COWLS) III: forecasts versus data

Natalie B. Hogg, James W. Nightingale, Quihan He +25

We compare forecasts for the abundance and properties of strong gravitational lenses in the COSMOS-Web survey, a deg survey of the COSMOS field using the NIRCam and MIRI…

The COSMOS-Web ring: Spectroscopic confirmation of the background source at z = 5.1

Marko Shuntov, Shuowen Jin, Wilfried Mercier +22

We report the spectroscopic confirmation of the background source of the most distant Einstein ring known to date, the COSMOS-Web ring. This system consists of a complete Einstein…

Measuring the Stellar-to-Halo Mass Relation at Solar masses, using forthcoming space-based imaging of galaxy-galaxy strong lenses

Kaihao Wang, Xiaoyue Cao, Ran Li +11

The stellar-to-halo mass relation (SHMR) is central to understanding the co-evolution of galaxies and their host dark matter haloes, yet it remains weakly constrained for dwarf gal…

Lopsidedness in Early-Type Galaxies: the role of the multipole in Isophote Fitting and Strong Lens Modelling

Aristeidis Amvrosiadis, James W. Nightingale, Qiuhan He +6

The surface brightness distribution of massive early-type galaxies (ETGs) often deviates from a perfectly elliptical shape. To capture these deviations in their isophotes during an…

Unveiling Lens Light Complexity with A Novel Multi-Gaussian Expansion Approach for Strong Gravitational Lensing

Qiuhan He, James W. Nightingale, Aris Amvrosiadis +8

In a strong gravitational lensing system, the distorted light from a source is analysed to infer the properties of the lens. However, light emitted by the lens itself can contamina…

Systematic errors induced by the elliptical power-law model in galaxy-galaxy strong lens modeling

Xiaoyue Cao, Ran Li, J. W. Nightingale +9

The elliptical power-law (EPL) model of the mass in a galaxy is widely used in strong gravitational lensing analyses. However, the distribution of mass in real galaxies is more com…
