Distance of W3(OH) by VLBI annual parallax measurement
K. Hachisuka, A. Brunthaler, Y. Hagiwara +4
The most powerful tool for measuring distances within our Galaxy is the annual parallax. We carried out phase-referencing VLBI observations of HO masers in the star forming r…
Extragalactic water masers in bright IRAS sources
A. Tarchi, C. Henkel, A. B. Peck +3
We report the results of a search for 22 GHz water maser emission in IRAS-bright galaxies, using the 100-m Effelsberg telescope. In particular, we present the details of four new m…
Observations of extragalactic masers in bright IRAS sources
A. Tarchi, C. Henkel, A. B. Peck +2
We report the first results of an ongoing survey at 22 GHz with the 100-m Effelsberg telescope to search for water maser emission in bright IRAS sources. We have detected water vap…
VLBA Observations and Effelsberg Monitoring of a Flaring Water Maser in Mrk 348
A. B. Peck, H. Falcke, C. Henkel +1
We report on single-dish monitoring as well as extremely high angular resolution observations of the flaring H2O maser in the Seyfert 2 galaxy Mrk 348. The H2O line is redshifted b…
A Flaring Megamaser in Mrk 348
A. B. Peck, H. Falcke, C. Henkel +4
We report new observations of the H2O megamaser in the Seyfert 2 galaxy Mrk 348. Following our initial detection in 2000 March using the Effelsberg 100 m telescope, re-analysis of…
The Dawn of Galaxies: Deep MAMBO Imaging Surveys
F. Bertoldi, K. M. Menten, E. Kreysa +2
We discuss results from sensitive, wide-field imaging of the millimeter extragalactic background using the Max-Planck Millimeter Bolometer array (MAMBO) at the IRAM 30m telescope.
