Multi-epoch VLBI of a double maser super burst
Ross A. Burns, Olga Bayandina, Gabor Orosz +20
In a rare and spectacular display, two well-known massive star forming regions, W49N and G25.65+1.05, recently underwent maser 'super burst' - their fluxes suddenly increasing abov…
Rapidly-evolving episodic outflow in IRAS 18113-2503: clues to the ejection mechanism of the fastest water fountain
Gabor Orosz, Jose F. Gomez, Hiroshi Imai +11
Water fountains are evolved stars showing early stages of collimated mass loss during transition from the asymptotic giant branch, providing valuable insight into the formation of…
VERA monitoring of the radio jet 3C 84 during 2007--2013: detection of non-linear motion
Koichiro Hiura, Hiroshi Nagai, Motoki Kino +13
We present a kinematic study of the subparsec-scale radio jet of the radio galaxy 3C 84/NGC 1275 with the VLBI Exploration of Radio Astrometry (VERA) array at 22 GHz for 80 epochs…
MultiView phase corrections at low frequencies for precise astrometry
Gabor Orosz, Maria J. Rioja, Richard Dodson +2
We present a multi-calibrator solution, i.e. MultiView, to achieve accurate astrometry on the level of the thermal noise at low VLBI frequencies dominated by ionospheric residuals.…
Bow shocks in water fountain jets
Gabor Orosz, José F. Gómez, Daniel Tafoya +4
We briefly introduce the VLBI maser astrometric analysis of IRAS 18043-2116 and IRAS 18113-2503, two remarkable and unusual water fountains with spectacular bipolar bow shocks in t…
