An extended and extremely thin gravitational arc from a lensed compact symmetric object at redshift 2.059

J. P. McKean, C. Spingola, D. M. Powell +1

Compact symmetric objects (CSOs) are thought to be short-lived radio sources with two lobes of emission that are separated by less than a kpc in projection. However, studies of suc…

Investigation of mass substructure in gravitational lens system SDP.81 with ALMA long-baseline observations

H. R. Stacey, D. M. Powell, S. Vegetti +2

The prevalence and properties of low-mass dark matter haloes serve as a crucial test for understanding the nature of dark matter, and may be constrained through the gravitational d…

Euclid: A complete Einstein ring in NGC 6505

C. M. O'Riordan, L. J. Oldham, A. Nersesian +195

We report the discovery of a complete Einstein ring around the elliptical galaxy NGC 6505, at . This is the first strong gravitational lens discovered in Euclid and the fi…

A grand-design spiral galaxy with an ordered magnetic field at redshift 2.6 as resolved with ALMA and gravitational lensing

W. de Roo, S. Vegetti, D. M. Powell +3

Magnetic fields play an important role in the evolution of galaxies and in shaping the dynamics of their inter-stellar medium. However, the formation history of magnetic fields fro…

A self-consistent framework to study magnetic fields with strong gravitational lensing and polarised radio sources

S. Ndiritu, S. Vegetti, D. M. Powell +1

We introduce a unified approach that, given a strong gravitationally lensed polarised source, self-consistently infers its complex surface brightness distribution and the lens gala…

A Multiwavelength Portrait of the 3C 220.3 Lensed System

Sóley Ó. Hyman, Belinda J. Wilkes, S. P. Willner +10

The 3C 220.3 system is a rare case of a foreground narrow-line radio galaxy ("galaxy A," ) lensing a background submillimeter galaxy (). New spe…
