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…
Evidence of a pure starburst nature of the nuclear region of NGC 253
A. Brunthaler, P. Castangia, A. Tarchi +4
We present high-resolution spectral line and continuum VLBI and VLA observations of the nuclear region of NGC 253 at 22 GHz. While the water vapor masers in this region were detect…
Distances to Galactic methanol masers
K. L. J. Rygl, A. Brunthaler, K. M. Menten +2
We present the first EVN parallax measurements of 6.7 GHz methanol masers in star forming regions of the Galaxy. The 6.7 GHz methanol maser transition is a very valuable astrometri…
J1128+592: a highly variable IDV source
K. E. Gabanyi, N. Marchili, T. P. Krichbaum +9
Short time-scale radio variations of compact extragalactic radio quasars and blazars known as IntraDay Variability (IDV) can be explained in at least some sources as a propagation…
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…
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…
