New Global VLBI observations of the gravitational lensing system MG J0414+0534
F. Volino, O. Wucknitz, R. W. Porcas +9
The gravitational lens system MG J0414+0534 is formed by an elliptical galaxy at redshift ~0.96 and a quasar at z~2.64. The system geometry is typical of lensing by an elliptical g…
The expansion of SN 2008iz in M82
A. Brunthaler, I. Marti-Vidal, K. M. Menten +7
We present first results from the ongoing radio monitoring of SN 2008iz in M82. The VLBI images reveal a shell-like structure with circular symmetry, which expands in a self-simila…
Discovery of a bright radio transient in M82: a new radio supernova?
A. Brunthaler, K. M. Menten, M. J. Reid +3
In this Letter, we report the discovery of a new bright radio transient in M82. Using the Very Large Array, we observed the nuclear region of M82 at several epochs at 22 GHz and de…
A gravitationally lensed water maser in the early Universe
C. M. V. Impellizzeri, J. P. McKean, P. Castangia +4
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…
