Disentangling the dark and stellar mass through precise lens modelling of the JWST observation of lensed quasar WFI2033--4723
Tian Li, Thomas E. Collett, Coleman M. Krawczyk +2
We use high-resolution JWST/NIRCam imaging and measured time delays to model the quadruply imaged quasar WFI2033--4723 with a composite stellar plus dark-matter mass model. We firs…
A Salpeter IMF and an NFW halo: Disentangling the dark and stellar mass of an elliptical galaxy through precise lens modelling of a double-source-plane system
Tian Li, Thomas E. Collett, Coleman M. Krawczyk +7
We present a strong lensing analysis of the double source plane lens J0946+1006 (colloquially "Jackpot" lens) to measure the inner dark matter density profile, the stellar-to-halo…
Stars as cosmic scales: measuring stellar mass with microlensed supernovae
Luke Weisenbach, Thomas Collett, Wolfgang Enzi +2
Gravitational microlensing is a unique probe of the stellar content in strong lens galaxies. Flux ratio anomalies from gravitationally lensed supernovae (glSNe), just like lensed q…
Unveiling a 36 Billion Solar Mass Black Hole at the Centre of the Cosmic Horseshoe Gravitational Lens
Carlos R. Melo-Carneiro, Thomas E. Collett, Lindsay J. Oldham +4
Supermassive black holes (SMBHs) are found at the centre of every massive galaxy, with their masses tightly connected to their host galaxies through a co-evolution over cosmic time…
How to Break the Mass Sheet Degeneracy with the Lightcurves of Microlensed Type Ia Supernovae
Luke Weisenbach, Thomas Collett, Ana Sainz de Murieta +4
The standardizable nature of gravitationally lensed Type Ia supernovae (glSNe Ia) makes them an attractive target for time delay cosmography, since a source with known luminosity b…
Detecting low-mass haloes with strong gravitational lensing I: the effect of data quality and lensing configuration
Giulia Despali, Simona Vegetti, Simon D. M. White +5
This paper aims to quantify how the lowest halo mass that can be detected with galaxy-galaxy strong gravitational lensing depends on the quality of the observations and the charact…
Systematic errors in strong gravitational lensing reconstructions, a numerical simulation perspective
W. Enzi, S. Vegetti, G. Despali +2
We present the analysis of a sample of twenty-four SLACS-like galaxy-galaxy strong gravitational lens systems with a background source and deflectors from the Illustris-1 simulatio…
