A lensed radio jet at milli-arcsecond resolution II: Constraints on fuzzy dark matter from an extended gravitational arc
Devon M. Powell, Simona Vegetti, J. P. McKean +4
Using a single gravitational lens system observed at milli-arcsecond resolution with very long baseline interferometry (VLBI), we place a lower bound on the mass of the…
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…
Dynamical properties of z dusty star-forming galaxies and their connection with local early type galaxies
Francesca Rizzo, Simona Vegetti, Filippo Fraternali +2
There is a large consensus that gas in high- galaxies is highly turbulent, because of a combination of stellar feedback processes and gravitational instabilities driven by merge…
A novel approach to visibility-space modelling of interferometric gravitational lens observations at high angular resolution
Devon Powell, Simona Vegetti, John P. McKean +3
We present a new gravitational lens modelling technique designed to model high-resolution interferometric observations with large numbers of visibilities without the need to pre-av…
Reducing Noise in Cosmological N-body Simulations with Neutrinos
Arka Banerjee, Devon Powell, Tom Abel +1
We present a new method for generating initial conditions for numerical cosmological simulations in which massive neutrinos are treated as an extra set of N-body (collisionless) pa…
The Doppler effect on indirect detection of dark matter using dark matter only simulations
Devon Powell, Ranjan Laha, Kenny C. Y. Ng +1
Indirect detection of dark matter is a major avenue for discovery. However, baryonic backgrounds are diverse enough to mimic many possible signatures of dark matter. In this work,…
Voids in cosmological simulations over cosmic time
Radosław Wojtak, Devon Powell, Tom Abel
We study evolution of voids in cosmological simulations using a new method for tracing voids over cosmic time. The method is based on tracking watershed basins (contiguous regions…
An exact general remeshing scheme applied to physically conservative voxelization
Devon Powell, Tom Abel
We present an exact general remeshing scheme to compute analytic integrals of polynomial functions over the intersections between convex polyhedral cells of old and new meshes. In…
