Neutral hydrogen absorption at milliarcsecond resolutions: The radio galaxy 3C293
R. J. Beswick, A. B. Peck, G. B. Taylor +2
We present new milliarcsecond resolution observations of the H1 absorption against the kiloparsec scale inner jet of the radio galaxy 3C293. Using a combination of observations obt…
Submillimeter Array observations of ISM in starburst galaxies
Kazushi Sakamoto, Satoki Matsushita, Alison B. Peck +5
The Submillimeter Array (SMA) has been under construction at the 4100 m summit of Mauna Kea, Hawaii. The array is going to allow imaging of lines and continuum at sub-arcsecond res…
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…
