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…
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) I: Discovery of >100 high redshift strong lenses in contiguous JWST imaging
James Nightingale, Guillaume Mahler, Jacqueline McCleary +27
We present the COSMOS-Web Lens Survey (COWLS), a sample of over 100 strong lens candidates from the \,deg COSMOS-Web survey, discovered using exquisite James Webb Space T…
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…
The onset of bar formation in a massive galaxy at
Aristeidis Amvrosiadis, Samuel Lange, James Nightingale +13
We examine the morphological and kinematical properties of SPT-2147, a strongly lensed, massive, dusty, star-forming galaxy at . Combining data from JWST, HST, and ALMA,…
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…
Abell 1201: Detection of an Ultramassive Black Hole in a Strong Gravitational Lens
James. W. Nightingale, Russell J. Smith, Qiuhan He +9
Supermassive black holes (SMBHs) are a key catalyst of galaxy formation and evolution, leading to an observed correlation between SMBH mass and host galaxy velocity di…
COSMOS-Web: An Overview of the JWST Cosmic Origins Survey
Caitlin M. Casey, Jeyhan S. Kartaltepe, Nicole E. Drakos +82
We present the survey design, implementation, and outlook for COSMOS-Web, a 255 hour treasury program conducted by the James Webb Space Telescope in its first cycle of observations…
Beyond the bulge-halo conspiracy? Density profiles of Early-type galaxies from extended-source strong lensing
Amy Etherington, James W. Nightingale, Richard Massey +9
Observations suggest that the dark matter and stars in early-type galaxies `conspire' to produce a surprisingly simple distribution of total mass, , with $γ\appr…
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…
Globular clusters vs dark matter haloes in strong lensing observations
Qiuhan He, Ran Li, Sungsoon Lim +4
Small distortions in the images of Einstein rings or giant arcs offer the exciting prospect of detecting dark matter haloes or subhaloes of mass below M, most of wh…
