Towards a kinematic model of the Local Group
A. Brunthaler, M. J. Reid, H. Falcke +2
Measuring the proper motions and geometric distances of galaxies within the Local Group is very important for our understanding of the history, present state and future of the Loca…
The Proper Motion of the Local Group Galaxy IC 10
A. Brunthaler, M. J. Reid, H. Falcke +2
We have measured the proper motion of the Local Group galaxy IC 10 with the Very Long Baseline Array by measuring the position of an H2O maser relative to two background quasars ov…
Water masers in the Local Group of galaxies
A. Brunthaler, C. Henkel, W. J. G. de Blok +3
We compare the number of detected 22 GHz H2O masers in the Local Group galaxies M31, M33, NGC6822, IC10, IC1613, DDO187, GR8, NGC185, and the Magellanic Clouds with the water maser…
Radio Linear and Circular Polarization from M81*
Andreas Brunthaler, Geoffrey C. Bower, Heino Falcke
We present results from archival Very Large Array (VLA) data and new VLA observations to investigate the long term behavior of the circular polarization of M81*, the nuclear radio…
The extreme flare in III Zw 2: Evolution of a radio jet in a Seyfert galaxy
A. Brunthaler, H. Falcke, G. C. Bower +3
A very detailed monitoring of a radio flare in the Seyfert I galaxy III Zw 2 with the VLA and the VLBA is presented. The relative astrometry in the VLBA observations was precise on…
