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…
Testing the isothermal Jeans model for self-interacting dark matter halos in the collapse phase
Shubo Li, Moritz S. Fischer, Zixiang Jia +3
We benchmark the semi-analytical isothermal Jeans model against a high-resolution isolated N-body simulation that follows a self-interacting dark matter (SIDM) halo into deep core…
Not so dark, not so dense: an alternative explanation for the lensing subhalo in SDSSJ0946+1006
Qiuhan He, Andrew Robertson, James W. Nightingale +12
Previous studies of the strong lens system SDSSJ0946+1006 have reported a dark matter subhalo with an unusually high central density, potentially challenging the standard cold dark…
Probing Dark Matter Substructures with Free-Form Modelling: A Case Study of the `Jackpot' Strong Lens
Xiaoyue Cao, Ran Li, James W. Nightingale +12
Characterising the population and internal structure of sub-galactic halos is critical for constraining the nature of dark matter. These halos can be detected near galaxies that ac…
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…
CSST Strong Lensing Preparation: Fast Modeling of Galaxy-Galaxy Strong Lenses in the Big Data Era
Xiaoyue Cao, Ran Li, Nan Li +4
Galaxy-galaxy strong lensing provides a powerful probe of galaxy formation, evolution, and the properties of dark matter and dark energy. However, conventional lens-modeling approa…
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…
Galaxy Mass Modelling from Multi-Wavelength JWST Strong Lens Analysis: Dark Matter Substructure, Angular Mass Complexity, or Both?
Samuel C. Lange, Aristeidis Amvrosiadis, James W. Nightingale +8
We analyze two galaxy-scale strong gravitational lenses, SPT0418-47 and SPT2147-50, using JWST NIRCam imaging across multiple filters. To account for angular complexity in the lens…
CURLING - I. The Influence of Point-like Image Approximation on the Outcomes of Cluster Strong Lens Modeling
Yushan Xie, Huanyuan Shan, Nan Li +11
Cluster-scale strong lensing is a powerful tool for exploring the properties of dark matter and constraining cosmological models. However, due to the complex parameter space, pixel…
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…
CSST Strong Lensing Preparation: Forecasting the galaxy-galaxy strong lensing population for the China Space Station Telescope
Xiaoyue Cao, Ran Li, Nan Li +8
Galaxy-galaxy strong gravitational lensing (GGSL) is a powerful probe for the formation and evolution of galaxies and cosmology, while the sample size of GGSLs leads to considerabl…
