A million-solar-mass object detected at cosmological distance using gravitational imaging
D. M. Powell, J. P. McKean, S. Vegetti +3
Structure on sub-galactic scales provides important tests of galaxy formation models and the nature of dark matter. However, such objects are typically too faint to provide robust…
SHARP -- IX. The dense, low-mass perturbers in B1938+666 and J0946+1006: implications for cold and self-interacting dark matter
Maryam Tajalli, Simona Vegetti, Conor M. O'Riordan +5
We present an extended analysis of the gravitational lens systems SDSS J0946+1006 and JVAS B1938+666. We focus on the properties of two low-mass dark matter haloes previously detec…
The preferentially magnified active nucleus in IRAS F10214+4724 - III. VLBI observations of the radio core
R. P. Deane, S. Rawlings, M. A. Garrett +5
We report 1.7 GHz Very Long Baseline Interferometry (VLBI) observations of IRAS F10214+4724, a lensed z=2.3 obscured quasar with prodigious star formation. We detect what we argue…
SHARP - I. A high-resolution multi-band view of the infra-red Einstein ring of JVAS B1938+666
D. J. Lagattuta, S. Vegetti, C. D. Fassnacht +3
We present new mass models for the gravitational lens system B1938+666, using multi-wavelength data acquired from Keck adaptive optics (AO) and Hubble Space Telescope (HST) observa…
