McKean, J. P., Auger, M. W., Koopmans, L. V. E., Vegetti, S., Czoske, O., Fassnacht, C. D., ...
The gravitational lens system CLASS B2108+213 has two radio-loud lensed images separated by 4.56 arcsec. The relatively large image separation implies that the lensing is caused by a group of...
Tracing the merger rate of the Universe with APERTIF and ASKAP (2009)
OH maser emission at 1.67 GHz is known to be associated with regions of intense star formation within ULIRGs. As these galaxies are formed through violent mergers, studying the co-moving density of...
A gravitationally lensed water maser in the early Universe (2009)
Impellizzeri, C. M. V., McKean, J. P., Castangia, P., Roy, A. L., Henkel, C., Brunthaler, A., ...
Water masers are found in dense molecular clouds closely associated with supermassive black holes in the centres of active galaxies. Based upon the understanding of the local water maser luminosity...
The role of luminous substructure in the gravitational lens system MG 2016+112 (2008)
More, A., McKean, J. P., More, S., Porcas, R. W., Koopmans, L. V. E., Garrett, M. A.
MG 2016+112 is a quadruply imaged lens system with two complete images A and B and a pair of merging partial images in region C as seen in the radio. The merging images are found to violate the...
