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…
