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…
