A lensed radio jet at milli-arcsecond resolution I: Bayesian comparison of parametric lens models
Devon M. Powell, Simona Vegetti, J. P. McKean +3
We investigate the mass structure of a strong gravitational lens galaxy at , taking advantage of the milli-arcsecond (mas) angular resolution of very long baseline interfe…
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…
Red nuggets grow inside-out: evidence from gravitational lensing
Lindsay Oldham, Matt Auger, Chris Fassnacht +7
We present a new sample of strong gravitational lens systems where both the foreground lenses and background sources are early-type galaxies. Using imaging from HST/ACS and Keck/NI…
Gaps in globular cluster streams: giant molecular clouds can cause them too
Nicola C. Amorisco, Facundo A. Gòmez, Simona Vegetti +1
As a result of their internal dynamical coherence, thin stellar streams formed by disrupting globular clusters (GCs) can act as detectors of dark matter (DM) substructure in the Ga…
On the density profile of dark matter substructure in gravitational lens galaxies
Simona Vegetti, Mark Vogelsberger
We consider three extensions of the Navarro, Frenk and White (NFW) profile and investigate the intrinsic degeneracies among the density profile parameters on the gravitational lens…
Parametrizing the Stellar Haloes of Galaxies
R. D'Souza, G. Kauffmann, J. Wang +1
We study the stellar haloes of galaxies out to 70-100 kpc as a function of stellar mass and galaxy type by stacking aligned and band images from a sample of 45508 galaxies…
